Hi,

We've a perfectly working code migrated (from .Net 3.5 Teleri 2009 Q2) to .Net 4.0 and Telerik 2011.

Almost all functionalites works fine except all the RadWindowManager $create(Telerik.Web.UI.RadWindowManager ..) calls fails
The call fails at a.beginUpdate() in the MicrosoftAjax.js  script line... it says "obeject property or method not supported"

All the RadWindow $create calls are working fine.

Urgent issue, Please help.

Thanks,

Gopi

Hi Gopinath,

We are aware of some problems that come from the fact that the js script file you have referenced (MicrosoftAjax.js) replaces some of the built - in js functions with others and in the case of RadWindowManager and RadToolTipManager in particular it introduces the observer context which is new in ASP.NET 4.0. We already found and fixed another problem related to this but as to the problem you currently report - we have not encountered it yet.

This being said, we will really need to examine a sample, fully runnable reproduction demo - please prepare such (include all the dlls you use as well, use a fake programmatic datasource if needed and make the demo as simple as possible), open a new support ticket and send it to us along with detailed reproduction steps. once we receive this, we will debug it on our side and we will do our best to help.

Regards,
Svetlina
