My grid is on ajax binding. And there are certain business rules when updating/deleting rows, so my GridAction method will throw an exception, a prompt stating "Error! The requested URL returned 500 - Internal Server Error" shows. Is there a way to show the actual error message from the exception, instead of always the standard general message. I can see the error in XMLHttpRequest of OnError event.

Or should I actually do the validation in OnSave client event, then cancel it in case of not valid.

Any suggestions? Thanks

Kan

Hello Kan,

 Using the OnError event is the recommended implementation. You can prevent the default error message dialog by cancelling the event and show the detailed info. Use the xhr (XMLHttpRequest) and its responseText property to get the server response.
