I have the same problem on one of my pages. I am using Beta 1. I am working around this by setting one of the UpdatePanel's UpdateMode to "Always". I am not sure if this would help on your page. Does anybody know how to correctly reference a control in a different content area, or if this is a limitation for UpdatePanels?

I think I have found a solution:

1.    Put your ScriptManager Control on your master page.

2.    Do not register your triggers in the <Triggers> section of your update panel, but instead add the following code to your Page.Init event:

        If Not Page.IsPostBack Then
            Dim trigger As New Microsoft.Web.UI.AsyncPostBackTrigger
            trigger.EventName = "Click"
            trigger.ControlID = btnSubmit.ClientID.ToString
            up1.Triggers.Add(trigger)
        End If

btnSubmit is my trigger, but you can substitute whatever trigger you have on your page for this.  Also, if you need to add more than one trigger, simply repeat the process in the Page.Init Event.

Please let me know if this works for you.  So far, it appears to be working for me...

One more thing.  I think it is clear from the above example, but "up1" is my UpdatePanel.

After some more testing, btnSubmit.UniqueID.ToString appears to work more consistently.

I tried this, but it does not work. I have a content area with three buttons and another content area with a multiview. Based on the button clicks, I want to show a specific view pane of the multiview. So the code behind each button is just - multiview.setactiveview - 0 or 1 or 2...

 The three buttons are not in update panel, but the multiview is. When I click on the buttons, the page refreshes. Using your method, I don't get the error anymore about "could not be found for the trigger in UpdatePanel", but the page refreshes on every click. However, if I move the buttons to the multiview content area, then the page does not refresh. I

 I would appreciate any help at all.

Thanks
 

Hi,

I think we can no more registering triggers like this in RC :

        If Not Page.IsPostBack Then
            Dim trigger As New Microsoft.Web.UI.AsyncPostBackTrigger
            trigger.EventName = "Click"
            trigger.ControlID = btnSubmit.ClientID.ToString
            up1.Triggers.Add(trigger)
        End If

Can anyone confirm ?

Try this one instead :

ScriptManager1.RegisterAsyncPostBackControl(yourControl);

How do you do that if the scrip manager is on the master page and the controls are in a content in a page that comes from master page?

Thanks 

Hi,

You have to expose your ScriptManager in a public property into your MasterPage codebehind.

Then you can do :

(MainMasterPage)Page.Master).YourProperty.... in your content page.

[But it's better if you have a Base Page as you do not have to cast]

Thanks,

I have solved my problem by doing the following..Please let me know if there are any negative issues with doing this.

I wrapped my 2 content areas in the master page in a update panel. Basicalle I put the content panes inside an update panel in the master page. Now on my other page, if I click on a button in one content area, both the contents get updated without the page being refreshed.

Thanks again. 

Hi,

I think it's ok for MultiView, anyway if you put the ContentTemplate inside an UP in MasterPage, you should read this :
