hi

I have a problem with C# when I use dropdown and customvalidation, with a textbos I can do it but not a dropdownlist

I want a error message when send "Select", if I use a textbox, my C# code is okay, but not with a dropdroplist, but I
find a solution for this problem.

I get this error with a dropdownlist:
Index and length must refer to a location within the string.
Parameter name: length

MY CODE:

<%@ Page Language="c#" %>
Go to the complete details ...
