Why not just use the maxLength attribute?

thanks buddy.
but the masLength attribute is present with TextBox,not with TextArea.
so i 'll have to fix that problem using javascript only.

the problem still persist.

In your very first post you told that you needed for Textbox and now you are asking for TextArea.
Just clarify it whether you are using textbox or textarea.

oh sorry buddy.
i'm using TextArea.

now can you help me please.....

Here is the code , in this code if you give more than 10 characters it will just erase them automatically.

Thanks alot.
