RadAjaxPanel Error

[Frank]

I am having trouble with a RadTreeView on a RadAjaxPanel. When any events are fired (say, NodeEdit) and handled on the server, I get a PageRequestManagerParserErrorException. I have read the posts related to this but none seem to apply. I am getting the following 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 'ipConfigure ESM 4.53'.

When I look at the response from the server it starts with:

ipConfigure ESM 4.53918|updatePanel|RadAjaxPanel1Panel|<div id="RadAjaxPanel1" style="height:200px;width:300px;">

I can only assume that this is the source of the problem, but I am not sure how to correct it. Any help would be appreciated.

Well, I though I didn't have any of the listed causes...but turns out there was a response.write hidden in the aspx page which was causing the problem. I removed it and problem went away. Thanks.
