  • Blank Page after removing Required Field Validator

    04-24-2008, 5:04 AM

    Hi,

    I'm using ASP.Net 2.0 with C#.

     I'm facing a unique problem.

     
    I had placed a validation summary and a required field validator.

    Now I removed the validation summary control.

    The page still works fine.

    But If I'm removing the required field validator then the page just display a white blank screen.

    I viewed the source and in that all the control and the html markup is proper and in place.

    What could be problem here?

     
    Thanks in advance.

    Maybe you did something in codebehind and forgot about it.
