Hi:

I was using Vs2005, and the next escenario is working OK, but last night I need to move into VS2008 and the escenario doesnt work.
I have in the master page a RadAjaxPanel with the contentplaceholder insidde it, so in the contentpages I have alll the logic, when I made a Postback in the content pages, it is converted into a callback, but since I move to VS2008 and framework 3.5 it doesnt work anymore. The loading image is not showing, and the postbacks are not converted.
Here it is:

MasterPage

I found the next issue, when the content page doesnt have a Telerik webcontrol, it stops working in this line of the file with this header:

/* START MicrosoftAjax.js */
//----------------------------------------------------------
// Copyright (C) Microsoft Corporation. All rights reserved.
//----------------------------------------------------------
// MicrosoftAjax.js

    
            if(b.skin!=""){if($telerik.isIE){if($telerik.$(f).css("filter").indexOf("opacity")!=-1||$telerik.$(f.firstChild.nextSibling).css("filter").indexOf("opacity")!=-1){g=false

The error it throws is: Microsoft JScript runtime error: Object doesn't support this property or method.

But if I put a Telerik webcontrol, specifically a RadCombobox in the content page it works.

Hey iomega 55,

If you are using AJAX.NET (i.e. .NET Framework 3.5 or later), then you need to use the latest version of controls dated May 2009 or later. Also, you can't use the telerik:RadScriptManager and telerik:RadAjaxPanels anymore, you need to replace them with AJAX.NET's asp:ScriptManager and asp:UpdatePanels. You can also replace telerik:RadAjaxPanels with asp:Panels and ajaxify them with a telerik:RadAjaxManager. If you must use the telerik:RadAjaxPanels, it might be possible, but it would mean that you can't use any of the features of AJAX.NET as they are not compatible.

Take it easy,
Bill
