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.

Upgrade to Beta 1 = New Rating control error

I installed the latest framework and toolkit.

My project was working fine with a wizard control that contained rating controls. I've taken the rating controls out of the wizard template and put them in their own update panel and still receive the error. It's a very strange behavior. If I make a new page and do everything, the rating control works fine. I'm using the latest control and did all the changes required to use the new Beta. After the install, I keep receiving this error when loading the page:

System.InvalidOperationException was unhandled by user code

Thanks

Anyone ? Can you please take a look? I believe others are experiencing something similar with the mentioned TargetControlID.

Thanks

When the project breaks, it breaks at the bold:

/// <summary>
/// On Init we load target properties values and process databinding handlers.
/// </summary>
/// <param name="e"></param>
protected override void OnInit(EventArgs e)
{
if (EnableClientState)
{
CreateClientStateField();
}
// EnsureProfileScriptService(ScriptManager.GetCurrent(Page), true);
Page.PreLoad += new EventHandler(Page_PreLoad);
base.OnInit(e);
}

Please reply with acomplete, self-contained sample page that demonstrates the problem. Thank you!

In my case the problem occures when I specify the rating control in the skin file.

Skinfile:

<

ajaxToolkit:Ratingrunat="server"StarCssClass="ratingStar"WaitingStarCssClass="savedRatingStar"FilledStarCssClass="filledRatingStar"EmptyStarCssClass="emptyRatingStar"/>
Good to know! Do you have a complete, self-contained sample we can play with?

Just add the following 2 lines in the Default.skin file of the Ajax Control Toolkit SampleWebSite:

<%@.RegisterAssembly="AjaxControlToolkit"Namespace="AjaxControlToolkit"TagPrefix="ajaxToolkit" %>
<ajaxToolkit:Ratingrunat="server"StarCssClass="ratingStar"WaitingStarCssClass="savedRatingStar"FilledStarCssClass="filledRatingStar"EmptyStarCssClass="emptyRatingStar"/>

Then try to open the Rating sample of the SampleWebSite.

The SampleWebSite doesn't have a Default.skin file - might there be something else going on here that's causing issues?
