Hello Carl,

I am attaching a simple example which works on my end with the suggested workaround. Give it a try and let me know if it works for you as well. Can you also let us know what is the exact error you are receiving and does the page work as expected if you replace our Ajax with MS UpdatePanel?

Kind regards,
Pavel

Here's the error that shows up in the Script debugger:

Object doesn't support this property or method Telerik.Web.UI.WebResource.axd?_TSM_HiddenField_=ctl00_RadScriptManager1_HiddenField&compress=1&_TSM_CombinedScripts_=%3b%3bSystem.Web.Extensions%2c+Version%3d4.0.0.0%2c+Culture%3dneutral%2c+PublicKeyToken%3d31bf3856ad364e35%3aen%3a363aef93-d081-4288-a122-fdd681803f66%3aea597d4b%3ab25378d2%3bTelerik.Web.UI%2c+Version%3d2009.3.1112.35%2c+Culture%3dneutral%2c+PublicKeyToken%3d121fae78165ba3d4%3aen%3afb9a8636-d7ff-417b-964e-98f159081a99%3a16e4e7cd%3aed16cbdc%3af7645509%3a24ee1bba%3ae330518b%3a1e771326%3ac8618e41%3a58366029%3aaa288e2d%3ae4f8f289, line 10611 character 67

The corresponding line in the script is:

if(this._disposeChildElements&&typeof(Sys.WebForms)!="undefined"){Sys.WebForms.PageRequestManager.getInstance()

Again, as reported in previous posts, everything worked fine in previous VS2008 with ASP.NET 3.5 sp1 and also everything continues to work in VS2010beta2 ASP.NET 4.0 as long as EnableAjax="false" but not when EnableAjax="true". I will try moving things out of the Master page and into the Content page.

Well thank you but I'm not sure that you have proven that it does work "on your end" because your test example does NOT include a Telerik RadGrid.

Further, following the example of what you did put in your test example, I could NOT get it to work. Now your test example had nothing but an <asp:ScriptManager> in the Master page and the <telerik:RadAjaxManager> in the content page, and I could not get that to work with a <telerik:RadGrid> also in the content page. Nor could I get the RadGrid to work with an <asp:UpdatePanel> in the content page.

In order for my application to work in a meaningful way in the environment which I have build up my code, there should be at least a ScriptManager and a RadMenu in the Master page and then a RadGrid in the content page. Where the RadGridManager is placed is up to you at Telerik, although it would be nice if it is possible to put a RadStyleSheetManager in the Master page. Whether you can prove that it also works with a RadGridManager and RadLoadingPanel or not is up to you at Telerik.

At this point, I have spent total of a day messing around with this, and I cannot get it to work. So I will not do any more testing unless I am "awarded Telerik points" for reporting and continuing to test the problems. Meanwhile, I am going to avoid wasting any more time by just reverting my project back to VS 2008 and Asp.Net 3.5 SP1 where it worked just fine!!!!!
