TextArea TextBox Maxlength doest not work when TextMode is set to Multiline

Hi,

This is known issue in ASP.NET Standard Text box control when set its TextMode="MultiLine" the MaxLength property does not work.

There is a workaround to accomplish this using RegularExpressionValidator. Following is the markup that will restrict the text box to maximum of 500 characters.

<asp:TextBox ID="txtComments" runat="server" TextMode="MultiLine" Height="100px"

Width="320px" MaxLength="10">asp:TextBox> <asp:RegularExpressionValidator

ID="regComments" runat="server" ControlToValidate="txtComments"

ValidationExpression="^[\s\S]{0,500}$" ErrorMessage="Maximum 500 characters are allowed in comments box." Text="Maximum 500 characters are allowed in comments

box." > asp:RegularExpressionValidator
