I am not sure how I can exactly display the database error message without it interfering with the Requiredfieldvalidator I know that I can turn off the requiredfieldvalidator, but I want them both to be able to work within my application. It's useless to have created a database error event handler if it will never be able to display the message in lblError inside of the GridView control just because the RequiredFieldValidator conflict with it. Can someone please help me? Here is my code below:
