I know this is a newbie issue so I’m hoping that somebody already has a work around beside. Response.redirect. So here is my situation. I have webfrom1.aspx with a button on it and in the click of the button on the server side I do a server.transfer to webform2.aspx. WebForm2.aspx contains a ToolkitScriptManager, a textbox and a CalendarExtender that points to the textbox. When webform2 loads I get an AjaxControlToolkit undefined error but if I do a Response.redirect everything works. So I assume webfor2 is fine and I need to do something with my web.config or webform1. Does anyone now how to get the ToolkitScriptManager to work when the page is called from server.transfer?

I don't know the exact cause of your error or how to fix it , but it may have to do with the differences between Response.Redirect and Server.Transfer.  Response.Redirect creates a new web request; it behaves similar to requesting a page through a browser.  Server.Transfer doesn't leave and "come back," it transfers processing to the specified page.  I think this difference could be the reason why your webform2.aspx doesn't like the Server.Transfer, it could be missing info from the web request.
