Sys.InvalidOperationException after F5 refresh

Hi
I've found a problem while using RadAjaxManager, a RadButton registered in its ajax setting to update an always visible asp.net panel containing an asp.net placeholder aimed to dinamically load an.ascx control (pnlItemDetails):

This is in a Content page:

<telerik:AjaxSetting AjaxControlID="BtnSelectItem">

<UpdatedControls>

<telerik:AjaxUpdatedControl ControlID="pnlProjectDetails" />

<telerik:AjaxUpdatedControl ControlID="PnlLocalMenu" />

<telerik:AjaxUpdatedControl ControlID="pnlItemDetails" />

<telerik:AjaxUpdatedControl ControlID="navBarFader" />

</UpdatedControls>

</telerik:AjaxSetting>

the panel with the place holder

<asp:Panel ID="pnlSelectedItem" runat="server">

<asp:Panel ID="pnlItemDetails" CssClass="ProjectDetails" runat="server">

<asp:PlaceHolder ID="phItemDetails" runat="server"></asp:PlaceHolder>

</asp:Panel>

All things works as expected until a browser refresh is invoked (by F5 or the 'File Download warning' bar of Internet Explorer).
After the page refresh, if the button is clicked, all server events are executed but at the client side, after the rendering phase, the following javascript error is triggered:

Sys.InvalidOperationException: Sys.InvalidOperationException: Could not find UpdatePanel with ID 'ctl00_ctl00_MainContent_pnlItemDetailsPanel'. If it is being updated dynamically then it must be inside another UpdatePanel.

Now, I know that this problem is often related to the update of conditionally visible controls, but I have a container asp.net Panel that is always visible and this behaviour is only present after F5 refresh triggering.

It'seems that the F5 refresh fail somehow to get the full DOM and update panels to refresh

Please, I need some help in finding the source of this issue.

Thank You in advance,
Federico

RadComboBox SelectedIndexChanged only fires when running in Asp.net Development Server

Hi,

We're having issues with a ComboBox that won't fire its SelectedIndexChanged event.

So I started doing some tests by first creating a new dummy page with nothing on it and confirming that the ComboBox does in fact fire it's SelectedIndexChanged event, which it does. This is a page with a RadComboBox, RadGrid, both of which make use of ObjectDataSources to populate their data. The RadGrid relies on a selection in the RadComboBox to populate.

My project page on the other makes use of nested master pages, with a script manager located in the Base.master.
The page itself has a number of controls including the RadComboBox and RadGrid.

Here are the results, which are disturbing to say the least:
1. Running my test page directly using IIS 7 works fine
2. Running my test page in the Asp.net Development Server (in VS2010) works fine.
3. Running my project page in the Asp.net Development server works fine.
4. Running my project page in IIS7 fails. No event firing for SelectedIndexChanged event.

How on earth is this even remotely possible?

Regards,
Jacques
