I have a data bound RadGrid that will bring up the first page, but when I try to move forward a page, I get the following error:

Error: Sys.WebForms.PageRequestManagerParserErrorException: The message recived from the server could not be parsed. Common causes for this error are when the response is modified by calls to Response.Write(), response fileters, HttpModules, or server trace is enabled.
Details: Error parsing near '><td>$0.00</td><td>'.

I have a RadAjaxManager on the page also, and based on a different post I found when looking up this error, I have the RadGrid calling itself. The above error is on different data each time. I am not using response.write in my code, but when I search for it in my project, it is in this file: Telerik.Web.UI.xml

Any idea on how to fix this?
Thanks, Amy

I had already tried the 2 things mentioned in the first article link, but they didn't help.

The problem seems to be with the response.write being using the file Telerik.Web.UI.xml:

(The below is from the second article link you gave me)

It seems the newer versions of AJAX.NET really hates having “Response.Write” being called while doing an Async postback. It changes the response a bit causing it a hard time extracting the changed values and updating the changes using JavaScript on the client side.

If you get this error go through your page and all the controls in it (including controls within controls) and make sure you don’t have a “Response.Write” in the markup page.

I don't want to take the response.write out of the Telerik.Web.UI.xml file, because what will happen when I go to upgrade the Telerik controls?
