I am getting the following error using an update panel with a gridview.
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.
I have looked at all the "fixes" for this and none of them seem to be working. It works just fine on page load but when I click my async button, One row of the grid processes (I can look in the javascript debug) but after the firstrow is processed, I get the above error at this line.
try { _this._webRequest.completed(Sys.EventArgs.Empty); } finally { if (_this._xmlHttpRequest != null) { _this._xmlHttpRequest.onreadystatechange = Function.emptyMethod; _this._xmlHttpRequest = null; } }
Here is my gridview

What I do in this code is convert a BLOB value from a database and store it in a string in a custom object. What seems to be happening is that there are odd characters being put at the end of the string. Here is what I am doing to convert the data
byteBLOBData = (Byte[])(row[3]);
row["data"] = System.Text.Encoding.UTF8.GetString(byteBLOBData);
One of the best ways to debug these issues is to inspect the AJAX response in Firebug and look for stray markup that doesn't belong. If you update your question with a copy/paste of that AJAX response, I can tell you which part shouldn't be there. Then, you know what to look for in your server-side code.
