UpdateProgress not showing.

I have an update panel that has 4 triggers to update it, and then I have an UpdateProgress that shows for that panel.

However the progress doesn't show unless a button in the panel is clicked, can it be made to show whenever the panel updates?

Thanks.

The UpdateProgress will not show automatically for any asyncpostback trigger. you have to manually show it. Check out this urlhttp://www.asp.net/AJAX/Documentation/Live/tutorials/ProgrammingUpdateProgress.aspx -Displaying Update Progress Using Client Script section.

Thanks! Will check into this.

Yes you have to see the online documentation

UpdateProgress panel positioning

I have a page that has a datagrid that can be quite long. I don't want to page it so a user sometimes scrolls down and then clicks a button in the grid.

The issue is that the updateprogress image is up at the top of the page and if a user scrolls and then clicks in the grid they don't see the progress image because it is up top.

Is there a way to put the updateprogress panel where the user clicked instead of up top in a set position all the time?

Hi,

You can set the position of the updateprogress image via javascript according to the button's position.

Thanks

UpdateProgress panel in a Gridview Row

Hi,

I have a linkbutton on gridview row that performs a function related to the row when it is clicked. I am trying to add an updateprogress Panel to each row to allow the user to know somethign is happening when button is clicked. I can not get this to work. in the row template I have the updateprogress panel and tied the event to the buton click on the row and basically all update panels in the rows show up and nothing happens when I click on a button. Does anybody have any ideas how to go about updateprogress in GridView Row?

Thanks,

Mo

Hi ,

From what I understand.

Why do you want dedicated UpdateProgress Panels for each row ? Cant just one Progress panel suffice?

If its a question of letting the user know which row is being updated, go with CSS / setLocation() to set the location of the Updateprogress Panel on the Page upon clicking the button

Thanks,

Phanatic

Hi,

The reason is wht you suggested. I have a progresspanel on top of the page but when a row is updated it may not be visible. I am not familia with CSS/SetLocation. Could you tell me more?

Thanks,

Mo

updateprogress panel for onLoad Event

I am creating a dashboard where I have four quadrants on the page. Each quadrant show data for a sql query. When the page loads I fire off all four queries to retrieve the data. I want to be able to show a progress indicator graphic inside of each quad as the data is retrieved and then rendered. How do I get the graphic to display in each quad as the page is loading?

Hi Joee,

UpdateProgress only shows during an asynchronous postback. In your situation, it won't be shown because it is a synchronous post back only. So we should add four UpdatePanel and its associated UpdateProcess to the page. When the page is shown, we force the four UpdatePanels be refreshed with the datas obtained from Database. To refresh the UpdatePanel, we should use __doPostBack("UpdatePanel's ClientID",""); or fire its trigger.

Hope this helps.

Best regards,

Jonathan

Jonathan, do I use JavaScript for the __doPostBack() and do I just put that in the head of the page?

Hi Joee,

joee:

do I use JavaScript for the __doPostBack()

Yes, but not the only way. You can put a hidden button which is the trigger of the four UpdatePanels and use Javascript to fire its click event. Also , we have other similar ways.

I hope this help.

Best regards,

Jonathan

Updateprogress panel does not disappearing

Hello:

I have a web page with updatepanel and updateprogress. In each callback, updateprogress is showed with a panel "loading".

My problem is that, if I call other web page that opens one PDF in other window, updateprogress does not disappear from the screen:

In button click I have:

Response.Redirect(

"getDocument.aspx",false); //This page does not load on same explorer. It is opened in other window

I have tried adding code at bottom of this sentence, like "UpdatePanel1.Update();" or updateprogress1.visible=false, but no way.

Any ideas?

Thanks and regards

How you are loading the response in another explorer using Response.Redirect or are you opening the window from the client side?

refer this tutorial also:

http://ajax.asp.net/docs/tutorials/ProgrammingUpdateProgress.aspx

referDisplaying Update Progress Using Client Script in the above page.This describes how to intercepte page request manager lifecycle.

Hello and thanks by responding:

I am calling a web page called Getdocument.aspx from code behind (on rowcommand of datagrid). Not from client-side.

This web page "GetDocument.aspx", generates a PDF file with Response.binaryWrite and open it in a new browser. But caller page remains or must remain active.

UpdateProgress panel

I'm using the updateprogress panel on my pages and when its "running" it moves my grid down on the page, is it possible to show it in a pop up window or show it overlaying my grid?

In essence, when I'm showing my "Processing" I want it either in a pop window or overlaying my grid view some how. can this be done?

Hi IGotYourDotNet,

You can take a look at theModalPopup orAlwaysVisibileControl because I think these have both been used by people on this forum for showing update progress.

Thanks,
Ted

ok thanks, I'll take a look at them.

also I currently have it on the page running and when the page errors out it shows a javascript alert box and doesn't take the user tomy error page. Is there a way to not show the javascript alert box and take them to my error page with using the updateProgress?

If I'm understanding correctly, I think you can just put the contents of your updateprogress info inside of a div and set the z-index. Like this:

1<atlas:UpdateProgress ID="UpdateProgress1" runat="server">2 <ProgressTemplate>3 <div style="z-index:100;position:absolute;left:10px;top:0px;">4 Loading...5 </div>6 </ProgressTemplate>7</atlas:UpdateProgress>

This will also position the progress at the very top left of the browser

I want it centered on the page, not in the corners of the browsers

IGotYourDotNet:

I want it centered on the page, not in the corners of the browsers

Just change the div style to this:

<div style="z-index:100;position:absolute;left:50%;top:50%;">

yeah i got it to work but I don't like how it looks. I'm going to look at the modal/popup to see if I can get that to work.

Also in using this, how can I still take my users to the error page (if it happens) and not show the javascript alert window like it currently does?

Hi,

I'm not very familiar withUpdateProgress, but if you ask this in the"Atlas" UI forum you should be able to find out.

Thanks,

UpdateProgress Problem

I'd like to show the update progress template in the center of div, which content is updated with update panel. I tried to do it with z-index.. but it works only with absolute positioning so it can be centered only in the whole browser window. What should i do to make it work in the right way? =)

Here is a simple illustration of the feature i need

*****************Update Panel*************
* *

* *

* Loading... *

* *

* *

**********************************************

I have anarticle on creating a modal UpdateProgress. It uses absolute positioning, but you can use relative positioning to position the message within your container. There is ademo available as well... you can use Firebug to mess around a bit with the styles in real-time (just disable the visible=hidden style on the UpdateProgress' main DIV).

Hope this helps.

-Damien

Everything work nice when we use absolute positioning.. but with realtive positioning z-index doesn't work so i failed to put it to foreground.

According tohttp://msdn2.microsoft.com/en-us/library/ms533005.aspx

It is quite possible that relatively positioned elements will overlap with other objects and elements on the page. As with absolute positioning, you can use the z-index attribute to set thez-index of the positioned element relative to other elements that might occupy the same area. By default, a positioned element always has a higher z-coordinate than its parent element so that it will always be on top of its parent element.

I also messed around with the styles on the sample I sent you using FireBug and verified that I was able to set the z-index on a relative positioned element. For example:

#processMessage {

background-color:#FFFFFF;

border:1px solid #000000;

left:43%;

padding:10px;

position:relative;

top:-300px;

width:14%;

z-index:1001;

}

UpdateProgress stops working

Hello everybody,

my problem: I have a gridview in an update panel, and the gridviews header contains some DropDownLists for filtering data. Also the Gridview is enabled for Sorting

and Paging. All works fine. But to inform the user that the action he started is on the way, i included a UpdateProgress with a gif animation. So when the user starts filtering

or sorting the gif animation is shown and animated. But after a short time, it stands still. A second or two later, the GridView is bound completely and the gif disappears.

So something seems to block the UpdateProgress. What am i doing wrong ? the gif animation is on top of the gridview.

any hint is aprreciated, thanks a lot !

This happens when the browser is rendering the response... Haven't found really anything to do about it :(

-Damien

UpdateProgress throws javascript error when contained in a Panel with visible = false

If you put a UpdateProgress control inside a Panel control with visible=false, you will get a javascript error that is cannot find the elements used for the update progress functionality.

Anyone, seen this before and know of a workaround?

I get the same result in a MultiView when the UpdateProgress control is contained in a view that is not the current view.

Thanks,

Ryan

When you set Visible equal to false the HTML contained therein does not get rendered at all. You shouldn't need to explicitly hide the UpdatePanel as it should hide itself unless an Atlas postback is in progress.

If you do need to hid it, set the style of the panel to "display: none" and leave it visible. That way the HTML will be rendered but not shown on screen.

Thanks for the suggestion on display: none. This will work for Panel controls, but it won't work for pages using the MultiView control. I guess I'll have to get rid of MultiView and create several separate panels wnd manually control which one is shown and which ones are diplay: none.

Updating an Update Panel on a page from Javascript

Hi All,

I am trying to update an update panel in a webform from Javascript. Form the documentation I think this might be possible using the Sys.Webforms.PageRequestManager but I have not been able to achieve this so far.

Any help would be greatful.

Hamlet

Hi Hamlet !

I been having the same wish ! After a lot of googeling the only way I found is to put an invisible button in a updatepanel and then raise it's postbackevent by registrering it's postbackevent in the scripthandler. Using the

$get('<%= YourControl.ClientID %>').click();

didn't work in FireFox and I supspect - but don't know for sure - not in ie7 ! One thing I wasted alot of time on was that the ValidateEventError but that was because I supplied an argument when registrering the clientscript in the scripthandler !

This feels like an uggly hack to accomplish what we want - but I didn't find any other way !

/MC24

I have been using

javascript:__doPostBack('__Page', 'some data' ) from the client.

This worked fine in the earlier release, but Beta 2.0 broke it because it started doing full postbacks instead of partial ones.

You can use the extender control I build.

updating an updatepanel...

Hi.

I'm sure the update panel is not just a clever name, but, it isn't doing what it ways on the tin!!

UpdatePanel1: Houses a databound GridView
UpdatePanel2: TextBox1 and ListBox1.

I have a page with a search form on. The user submits search criteria which fire a conditional update of UpdatePanel1. The GridView re-binds itself perfectly! Now, I used to have some javascript which picked up the selected value of Listbox1 and dumped it out to TextBox1, it worked fine, until, I installed the latest release of the toolkit and now the javascript cannot find the form object.

No matter, I thought, I'll use an update panel and set it to conditional update and uses ListBox1.SelectedIndexChanged to fire the update, dumping the selected value into TextBox1. So I wrapped TextBox1 in UpdatePanel2 and run the code... nothing happened, until, I hit the search button which fires the update of UpdatePanel1. When I click this button both panels update?

So I thought I'd try putting ListBox1 outside of the UpdatePanel2... still no joy, exactly the same thing happened when the search button is clicked.

I then tried forcing the UpdatePanel2 to update in the code behind using, amazingly, UpdatePanel2.Update()... Guess what... nothing, until I hit the search button again.

I have double checked and both panels are setup as follows: UpdateMode="Conditional" ChildrenAsTriggers="False". My Script manager has Partial Rendering set to true. Both Update Panels have the correct triggers i.e UpdatePanel1 = Button1.click and UpdatePanel2 = ListBox1.SelectedIndexChanged

Anybody have any ideas? I can post the code up if required.

Thanks in advance.

I was able to recreate your example, with a listbox and textbox, populating the textbox on the listbox_SelectedIndexChanged event. At first, it would fire and fire and fire, but the textbox wouldn't update.

The kicker was changing ChildrenAsTriggers="True". See if that doesn't help.

Thanks Dugald.

I tried this but still no luck. Is your ListBox inside or outside the update panel?

I'm not convinced that the event is firing or not in al hoensty! I've tried adding an UpdateProgress template and adding sleep to the thread of 2 seconds but I still see nohting.

Just to confirm your setup.

ScriptManager: PartialRendering="True"
UpdatePanel: UpdateMode="Conditional" ChildrenAsTriggers="true "
ListBox: OnSelectedIndexChanged="ListBox1_SelectedIndexChanged"

?

Have you tried setting a breakpoint in the event code to verify the event is firing?

Here is the code for my simple test:

<%@. Page Language="C#" EnableViewState="true" AutoEventWireup="true" CodeFile="Default.aspx.cs" Inherits="_Default" %><!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.1//EN" "http://www.w3.org/TR/xhtml11/DTD/xhtml11.dtd"><html xmlns="http://www.w3.org/1999/xhtml"><head runat="server"> <title>Untitled Page</title></head><body> <form id="form1" runat="server"> <asp:ScriptManager ID="ScriptManager1" EnablePartialRendering="true" runat="server"> </asp:ScriptManager> <asp:UpdatePanel ID="UpdatePanel1" runat="server" ChildrenAsTriggers="True" UpdateMode="Conditional"> <ContentTemplate> <asp:ListBox ID="ListBox1" runat="server" AutoPostBack="True" OnSelectedIndexChanged="ListBox1_SelectedIndexChanged"> <asp:ListItem>Alpha</asp:ListItem> <asp:ListItem>Bravo</asp:ListItem> </asp:ListBox> <asp:Button ID="Button2" runat="server" OnClick="Button2_Click" Text="Button" /><br /> <br /> <asp:TextBox ID="TxtTarget" runat="server" ForeColor="Black"></asp:TextBox> </ContentTemplate> </asp:UpdatePanel> <asp:Button ID="Button1" runat="server" Text="Full Postback" OnClick="Button1_Click2" /> <asp:TextBox ID="TextBox1" runat="server"></asp:TextBox> </form></body></html>

using System;using System.Data;using System.Configuration;using System.Web;using System.Web.Security;using System.Web.UI;using System.Web.UI.WebControls;using System.Web.UI.WebControls.WebParts;using System.Web.UI.HtmlControls;public partialclass _Default : System.Web.UI.Page {protected void Page_Load(object sender, EventArgs e) { }protected void Button1_Click1(object sender, EventArgs e) { }protected void ListBox1_SelectedIndexChanged(object sender, EventArgs e) { TxtTarget.Text ="Changed";// ListBox1.SelectedValue; }protected void Button2_Click(object sender, EventArgs e) { TxtTarget.Text ="Pushed"; }protected void Button1_Click2(object sender, EventArgs e) { TxtTarget.Text ="Posted"; TextBox1.Text ="Posted"; }}

Ok, after adding a breakpoint on the ListBox1_SelectedIndexChanged event. I can see that the event is not even firing?
Try deleting the event and recreating it.

AHHHHHHHHH!!!!!!!!!!!!!!

Amazing what AutoPostBack="True" does!

Thanks for your help Dugald! Sorry for the Noob error...

Updating an UpdatePanel through a LinkButton command generated by a repeater

Hi everybody,

I would like to refresh an update panel when I click on a Linkbutton generated by a repeater that looks like this:

<asp:Repeater ID="Repeater1" runat="server" DataSourceID="SqlDataSource1">
 <ItemTemplate>
 <li>
 <asp:LinkButton ID="LinkButton1" runat="server" OnCommand="FilterByPrize" CommandName="filter" CommandArgument='<%# DataBinder.Eval(Container.DataItem, "NameID")%>'>
<%# DataBinder.Eval(Container.DataItem, "Name")%> </asp:LinkButton>
 </li>
 </ItemTemplate>
</asp:Repeater>

The command called is the following:   

 protected void FilterByPrize(object sender, CommandEventArgs E){string connString ="connstring"; SqlConnection IVR =new SqlConnection(connString);string finalquery ="sqlquery " + E.CommandArgument.ToString() +" order by TimeStamp desc"; SqlDataSource2.SelectCommand = finalquery; SqlDataSource2.DataBind(); userData.DataBind();} 

The problem with this is that it reloads the whole page instead of only the update panel. Is there a way to refresh the updatepanel from a function in the c# code called from a linkbutton?

Thanks

MrClash,

The update panel has an Update() method that will do this. But I'm afraid that you are going to have register the linkbutton with the update panel. Take a look at this thread.

Good luck! And feel free to provide some more details if this doesn't work.

updating form updatepanel to updatepanel or one to many updatepanel

Hi all,

i have two updatepanels.

<updA>

<uc1 ..ascx> [...Reload this control or updating this panel ]

</updA>

<updB>

<uc2 ..ascx> [...onclick event ]

</updB>

i hope you anyone can solve this..

thanks

pkay

I am not sure what is your question. Can you please clarify? Thanks

When an updatePanel is updated, all the other updatePanels on the page also are updated.

This means that both <updA> and <updB> will be updated if you update one of them.

To avoid this, you can play with the "updateMode" updatePanel's property. This property is set to "always" by default but you can change it to "conditionnal" and then choose by yourself when your update panel has to be updated.

Hope it helps

Updating MasterPage panel from content page

Hello,

I have created a shopping cart which users can add products to within an update panel in a content page. However in the masterpage there is a 'basket' that displays how many products are currently in the basket. I need to find a way of updating this basket whenever the updatepanel in the content page is reloaded. Is this possible.

Thanks,

Curt.

Yes, create a Public Property on your Master Page and set the baskek based on this value. The value can then be updated from your content page (you can get access to the Master Page via Page.Master).

Thank you for your reply.

Could you give me some more help on how to do this as I don't have much experience with Public Properties just yet?

Thanks.

Here's a sample Public Property with a type of String:

Public Property Name()As String Get Return _NameEnd Get Set(ByVal valueAs String) _Name = valueEnd Set End Property

Updating one Ajax Panel from another

I have two pannels one is a grid and the other is the details pannel. Once you click on the grid the details panel is updated (the grid is a trigger to the detials). What i need is once the user update the details panel, the original grid needs to be update with the new information. If i set a button on the details panel as the trigger for the grid panel, it does not work (recursive triggers?).

How do i do it?

Hi,

if your panels UpdateMode is conditional, you can always rely on Update method to force updatePanel refresh from your server code.

-yuriy

You have to set UpdateMode="Conditional" & have to be use UpdatePanel.Update() method.

updating only portion of a User control

Hi,

I Have an application Where I am dyanmically Loading User controls in a Main Page Content area(in an Update Panel)

And Each user control has its own update panel. for Example I have a List box and a text box and the Text box is in an update panel

And when the user select an item in the list box i need to update the text box upadate panel.

But the problem is since all these controls are in a user control and the user control loads in a place holder in an update panel in my main page.

To get the events of the user control child controls i need to load it again while asynchrounous post back

ie When user selects a menu item i am loading my user control into a place holder in an update panel in the main page.

and when the user clicks on the list box in my user control to get the selected index changed event i need to load the user control again

in my cs code. to the place holder . but i am only updating the text box in my user control. and so i placed that in an update panel.

but the problem is since my user control is inside an update panel in my main page the whole user control get refreshed.

I put the update mode of my main page update panel as conditional and when the user double clicks on the list box i load the user control in the palce holder so that i will get the events but i didn't update the main update panel. I did call only update for the update panel for the text box(which is in my user control)

but still my whole user controls get refeshed . Is there any solution for this

Thanks and regards

Where the control that make posteback is located , is it inside your main update panel ?

if yes so you have to set "ChildrenAsTriggers" of your main update panel to false.

please let us know about your aspx code

HiI have a Main page where there is an update panel( where a place holder exists )which is made as conditionalAnd I have user controls(ascx) which are dynamically loaded into this update panel-into the place holder-(when user clicks on different menu items in main page. And inside each user Control there is an update panel where all child controls are placedand I may have update panels for individual controls in user controlfor example in one of my user control I have a list box and a text box and when i double click on the list box i need to change the text box value so i kept the text box inside an update Panel. but the problem is when i click on the list box in a user control if i need to get the event(selected indexchnaged) for that user control i need to load it again to the place holder in the cs file(Main.aspx.cs), ie if may user control name is search.ascxi am usong LoadControl method and adding it to the placeholder in my main page(this should happen each time when any postback occurs because of an event for a child control in the user control- then only i will get its events).I kept all update panel's update mode as conditional. and I will call only update for the update panelwhre my text box exists ( ie the update panel inside my user control). I only call Update for my main update panelonly when I need to load another user control ie when the user selects another menu item from the main page. mainupdatepanel -- Upadated only when new user control is to be loade usercontrolupdatepanel - Updated conditionally usercontrolchildcontrolUpdatepanel-- updates conditionallyThanks and Regards

Or add a button beside file upload control with name "Upload file" and add postback trigger to update pannel for that button click event. File will be uploaded when this button is pressed but page then will do normal postback
