I get this error, Sys.WebForms.PageRequestManagerServerErrorException: An unknown erro occured while processing the request on the server. The status code returned from the server was: 500, when I click a command button on a grid row.
I can not reproduce the error in VS with IE 7, but the client gets it in IE 6 and IE 7. I am debugging with the same database as the client and entering the same values in the form. I do not get the error.
Is this a data validation issue? Should I implement RequestValidation=False?
Why can't I reproduce it?
