TextBox - MaxLength property

[mg]

I have a MultiLine TextBox (WebForm - C#) with the MaxLength property = 1000 but am able to type in an unlimited number of characters. Is there a way to limit the number of characters that can be typed into this TextBox?

MaxLength property works only with single-line TextBox (its not about
ASP.NET but HTML and how TEXTAREA vs INPUT behaves). You'd need to write
custom validation to check the length when typing.

As Teemu pointed out, this is a limitation of the multi-line TextBox,
and you need to use a custom validator and (ideally) client-side
JavaScript to limit this. See
http://forums.aspfree.com/showthread.php?t=18846 for a discussion of how
to write some client-side JavaScript to not permit the user to enter
more than a specified number of characters...

Hope this helps...
