Weird ?: MultiPage Disappearing When Added to RadAjax

[James]

Hi,

Weird problem.  Here is what I am trying to do:  On the drop of a node, change my tab by setting the SelectedIndex of my TabStrip and Multipage to a selected value.  Specifically, I expect the code to work as follows:

1. The node is dropped.
2. I run the following code on the server:

3. RadTabStrip1.SelectedIndex = 3
   RadMultiPage1.SelectedIndex = 3

4. The Ajax Manager catches the change of the TabStrip and MultiPage.
5. And then moves to the correct tab.

However, when just the TabStrip is added to the Ajax manager, the tab changes but the MultiPage does not (See screen shot one.).  When the MultiPage is added to the Ajax manager, the PageView disappears entirely (See screen shot two.).  Crazy.  I've also tried this version of the server side code:

RadTabStrip1.Tabs.Item(CInt(myTab)).Selected = True
RadMultiPage1.SelectedIndex = CInt(myTab)

I'm pretty sure my server side code is correct, as I've tested it every which way but loose.  Any ideas?

For reference, here is the .aspx of my TabStrip, etc. (Sorry it is so long.  Big app.):

Thanks so much for any help you can give.

I figured it out.  It is that mystical RadAjaxManager.  It didn't want the Grid referenced directly.  It only wanted the pages referenced within the MultiPage control.  Like this:

<telerik:RadAjaxManager runat="server" ID="RadAjaxManager1">
            <AjaxSettings>
                <telerik:AjaxSetting AjaxControlID="RadTreeView1">
                    <UpdatedControls>
                        <telerik:AjaxUpdatedControl ControlID="RadTreeView1" />
                        <telerik:AjaxUpdatedControl ControlID="RadTabStrip1" />
                        <telerik:AjaxUpdatedControl ControlID="RadMultiPage1" />
                    </UpdatedControls>
                </telerik:AjaxSetting>
            </AjaxSettings>
        </telerik:RadAjaxManager>
