    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?




    @ Control Language="VB" AutoEventWireup="false" CodeFile="Test.ascx.vb" Inherits="Apps_MapViewer_Test" %>




    @ Register Assembly = "AjaxControlToolkit" namespace="AjaxControlToolkit" tagprefix="ajaxToolkit"%>

    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.
