Custom Control Update Error

[Liza]

Hi! Maybe you can help me! I'm building a custom control for a radgrid and when I'm trying to perform and update it keeps showing me this error: "Sys.WebForms.PageRequestManagerServerErrorException: An unknown error ocurred while processing the request on the server. The status code returned from the server was: 500."

I tried to debug the code, but the error its generated when I just simply click the button.

Thanks

Hi again!! I Found the answer, all i had to do was to add 

<%@ Page Language="VB" ValidateRequest="false" %>

into the page header.

Thanks,

Liza
