OK, we're almost there. I updated VS2008 to SP1. That solved the problem with the configuration dialog to display the controls.
Second, I added a RadAjaxPanel to my Master Page and configured it. This does "ajaxify" all of my pages. I also changed the existing web forms that had AjaxManagers on them to be RadAjaxManagerProxy controls and this is working.
The final issues is with all of my pages that have a Response.Redirect() command. Anytime issuing this causes an error. Here is the error:
Microsoft JScript runtime error: Sys.WebForms.PageRequestManagerParserErrorException: The message received from the server could not be parsed. Common causes for this error are when the response is modified by calls to Response.Write(), response filters, HttpModules, or server trace is enabled.
Details: Error parsing near '
<!DOCTYPE html PUB'.
I followed the directions for issuing the following command to replace the Response.Redirect command:
This causes an error as the object has not been initialized. Please advise as to what I am missing here.
