Before updating a datarow, its quite oftern for a data-bind form to check
each control's data is valid first, before commit the changes on the
datatable.

I want to validate the current data row before it is updated to the
datatable on a data-bind form. Is there any event for triggering such update
action or whats the usual practice for implementing such checking? So that I
can ensure each control user input is valid and instruct user to correct any
error beforehand.

Thanks in advance!
 
thanks again! this is the event I'm looking for, I will implement the logic
on Rowchanging event then!
