Hello,
today, I spent hours trying to solve a
"Sys.WebForms.PageRequestManagerParserErrorException"
on the radgrid.
It happened only for some records. After some time, I narrowed it down to one single record.
Then I noticed, even in SQL Server, the record was truncated. Impossible to read beyond a certain point.
The radgrid was still able to show the whole record, but only on the page load: any async request would cause a:
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 ' to move '.
After a few more hours of digging, I noticed firefox had no problems at all displaying the record, even in async postbacks...
And finally, I noticed the cause: in the middle of the record.
(Not even sure this will display for IE users)
A little ascii square!
So much pain, for one ascii square...
So many articles, so many forum threads... None ever mentionned this.. So I thought there should be at least one forum thread about this...
Good luck to anyone stumbling on this while searching for a mystical "Sys.WebForms.PageRequestManagerParserErrorException".
Those are hard...
