ERROR - BulletedList and AJAX Toolkit

Error : Generation of designer file failed: The server tag 'asp:BulletedList' is ambiguous....
(if an Ajax Toolkit Manager and a BulletedList placed in same page(.aspx))

Reason: Same "TagPrefix"  'asp' to AJAX toolkit controls and ASP.NET controls

Solution:

<%@ Register Assembly="AjaxControlToolkit" Namespace="AjaxControlToolkit"
 TagPrefix="asp" %>

<asp:ToolkitScriptManager ID="ToolkitScriptManager1" runat="server">  
    </asp:ToolkitScriptManager> 

//Modify like this.

<%@ Register Assembly="AjaxControlToolkit" Namespace="AjaxControlToolkit"
TagPrefix="ajx" %>

 

<ajx:ToolkitScriptManager ID="ToolkitScriptManager1" runat="server">  
    </ajx:ToolkitScriptManager>
