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.
