try this the following, this will prevent user from entering more
characters than maxLen specified; it works in all the situations,
including:
1) copy and paste;
2) insert key on;

Hi Guys..
its me again.. ;o))
now i have a TextBox with properties Textmode = singleline and MaxLength =
100. So this works fine and i cannot enter more then 100 Chars. But as soon
as i change the TextMode to MultiLIne the MaxLength gets ignore as it is
painted as TEXTAREA. so how do i add a validator control to make sure that
user is not entering more than 100 Characters..
Thank you for the help in advance.
RSB.
