这是我按lnkExportCSVWO时发生的错误。 This is in inspect element in browser:
Here is the error that happens when I press lnkExportCSVWO. This is in inspect element in browser:
Uncaught Error: Sys.WebForms.PageRequestManagerParserErrorException: The message received from the server could not be parsed.

For try-catch in the program:
For try-catch in the program:
ex = {Unable to evaluate expression because the code is optimized or a native frame is on top of the call stack.}
lnkExportCSVWO is not working but lnkExportCSV is working and they both have the same codes. Both link buttons should export a CSV from a Gridview.
What I have tried:
Haven’t found a solution yet in google that is the same as mine.
