Toolkit, ScriptManager and Master Page

Question

User1510859543 posted

Our asp.net site uses master pages on most all pages in the website.  I want to make ajaxtoolkit available on all pages that use the master page and only use UpdatePanel on some of those pages.  Which control do I use and where should they be placed?  On some pages I am getting "Unknown server tag 'asp:CalendarExtender'" message.  Thanks.

add toolkitscriptmanager in master page

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

add updatepanel only on those content pages where u want to use it

also, make sure to make changes in web.config after adding reference to ajaxcontroltoolkit assembly

Can it go anywhere in master page body?  Also, does the below need to only be on the master page or on all pages?

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

When I take the register line out of the content page that is when I get the Unknown server tag 'asp:CalendarExtender' error.

The reason why you are getting the warning is that you have given the same "TagPrefix", asp, to AJAX toolkit controls. The "asp" TagPrefix is used for ASP.NET controls by default.  Just give a different TagPrefix to the AJAX controls and that should solve your problem.
