RadDockLayer error when using ajaxControlToolkit PopupControlExtender

[Ajit]

I am trying to use ajaxToolKit's PopupControlExtender control inside of the TitleBarTemplate inside a RadDock inside of an ASCX file. This works fine when viewed in a browser, but Visual Studio's design view gives this error:

Error Creating Control - RadDockLayout
Unable to create type 'ajaxToolkit"PopupControlExtender'. Could not load assembly 'System.Web.Extensions....' or one of its dependecies. Tye system cannot find the file specified. What am I doing wrong?

is it a problem with the web.config file?

Thanks,

Ajit

Hi Ajit,

I tested the code you sent and everything seems to be fine under VS2005. It seems that you don't have a System.Web.Extensions.Design.dll added to the GAC.

P.S. Keep in mind that there is a problem with the ContentTemplate tag when a control is added inside the RadDock at design time. The ContentTemplate tag disappears and should be added manually.
