Hi 1.CustomValidator Performs user-defined validation on an input control. The control allows you to validate both clientside and serverside where the serverside approach is probably the most powerful. 2.Example : Check the length of the string in the TextBox using CustomValidator. Custom text: protected void cusCustom_ServerValidate(object sender ServerValidateEventArgs e) { if(e.Value.Length == 8) e.IsValid = true; else e.IsValid = false; } Hope this will help you. Thanks.
