TextBox - MaxLength property

[Guest]

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?

only the TextBox.TextMode = "singleLine" or "password" , the
TextBox.MaxLength property is valid
so when you set TextBox.TextMode=MutilLine, the MaxLength property not valid
