UpdateProgress not showing up

I have a page which has a FormView control and when I click one of the rows I get an ModalPopup for editing the detailed information. This works, however it takes too long for ModalPopup to open. Since I haven't found any solution for speeding up the ModalPopup, I thought I might as well inform the user that the data is loading on the background. I also thought that I might give UpdateProgress-control a try. I know that this is not the best solution for this (performance) issue but so far is the best I can figure out.

My page looks like this:

<Button> (hidden)
<ModalPopupExtender>
<Panel>
<UpdatePanel>
<FormView>
</UpdatePanel>
<UpdateProgress>
</Panel>

So what I would like is that before ModalPopup is visible, user gets an message presented by UpdateProgress, that something is going on. However with this current setup, nothing happens, UpdateProgress is not activated. Any ideas why ?

The ModalPopupExtender and the popup control have to be inside the UpdatePanel for UpdateProgress to be activated.

Hi,

Here an example of how to procede with.

<asp:UpdatePanelID="UpdatePanel1"runat="server"UpdateMode="Conditional">

<ContentTemplate>

<!-- Place here your ModalPopupExtender and the popup control -->

</ContentTemplate>

</asp:UpdatePanel>

<asp:UpdateProgressID="UpdateProgress1"DynamicLayout="false"runat="server"DisplayAfter="50">

<ProgressTemplate>

<spanstyle="font-family: Trebuchet MS; color: #ffffff;">Chargement...</span</ProgressTemplate>

</asp:UpdateProgress>

<ajaxToolkit:AlwaysVisibleControlExtenderID="AlwaysVisibleControlExtender1"runat="server"TargetControlID="UpdateProgress1"HorizontalSide="Center"VerticalSide="Middle"HorizontalOffset="0" />

Kind regards,

Ok,

Thanks both, I try to take look at this bit more today.

I tried this and it works, thanks !

One question though, why is AlwaysVisibleControlExtender needed, because the examples I have seen are done without this ? I always thought that UpdateProgress would be the only control needed here.

Happy to see that it works.

This extender is just here for managing the UpdateProgressExtender position. As you can seeHorizontalSide="Center"VerticalSide="Middle"

are for specifying the position in the screen where you would like to have the loading displayed, and even if you are scrolling up and down inside the page, you'll see that the position will always stay where you define it.

Kind regards,

Ok, now I see why it's needed. Thanks again.

UpdateProgress not reacting to LinkButtons in MultiView and FormView

I have a Content Page with two UpdatePanels. The first one has a FormView inside it and second one has MultiView with several Views. In each of this views I have a GridView in it. I change the views by LinkButtons that are also in the same UpdatePanel.

My problem is that none of the PostBack events in the UpdatePanels seem to fire the UpdateProgress. However, if I add a third UpdatePanel with a Label and a Button whith the following code, it does react to the Button click.

ProtectedSub btnTest_Click(ByVal senderAsObject,ByVal eAs System.EventArgs)

System.Threading.Thread.Sleep(3000)

lblTest.Text = DateTime.Now.ToString()

EndSub

But it still won't react to the events in the other two panles. Am I doing something wrong? All help would be greatly appriciated.

Thank you.

One more thing:

I can also move the Label and the Button to one of the exisiting UpdatePanels and the Button Click event does fire the UpdateProgress correcctly.

I also have two DropDownLists in the FromView (located inside a UpdatePanel) with PostBack events. Shouldn't that trigger the UpdateProgess?

Anyone?

Thank you.

I did some futher testing and noticed if I copy the following in the LinkButton Click Sub, the UpdateProgress shows for that 3 seconds:

System.Threading.Thread.Sleep(3000)

So basically it seems only to work when sleeping but not when doing actually something, like sorting data in the GridView.

Is there anyway to fire the UpdateProgress manually?

Found an interesting link that almost (but not quite) handels my problem:

http://smarx.com/posts/why-the-updateprogress-wont-display.aspx

I tryed to use UpdatePanelAnimationExtender instead and found out a strage thing. When using the following code clicking the button that does that sleep thing, everything works fine. But when I do any other action on the that UpdatePanel (click a LinkButton that chages the active View, sort data in the GridView) the OnUpdating animation (FadeOut) only begins and then stops for several seconds until the data is rendered and then the OnUpdated animation (FadeIn) runs entirely. Strange!

<cc1:UpdatePanelAnimationExtenderID="UpdatePanelAnimationExtender1"runat="server"TargetControlID="upnDataTabs">

<Animations>

<OnUpdating>

<FadeOutDuration="1"Fps="40"/>

</OnUpdating>

<OnUpdated>

<FadeInDuration=".5"Fps="20"/>

</OnUpdated>

</Animations>

</cc1:UpdatePanelAnimationExtender>

I seem to be talking to myself here... MUST TAKE MY MEDICAION
