how to limit input with textbox multiline?

[Terry]

Hi,

i want to limit input in this textbox up to 2O characters, but i can input a
unlimited amount of characters. How to limit that?

<asp:TextBox ID="txtStreet" runat="server" Width="200px" MaxLength="20"
rows="2" TextMode="MultiLine"/>


Thanks
Terry

You can't do it using standard properties, for example, there is the
MaxLength property, which has no effect in a multi-line textbox.

Possible workarounds:

1. JavaScript
2. Codebehind
3. CustomValidator
