    Hi shsu ,

    You can try :

     <asp:RegularExpressionValidator ID="regularExpressionValidator1"
     ControlToValidate="YourTextBoxID" runat="server" 
     ValidationExpression="^[\s\S]{0,200}$" Text="200 characters max" />

    Or directly force max length of a text box field :

    <asp:TextBox MaxLength="200" id="textbox1" runat=server> </asp:TextBox> 

    Best Regards,

    Nan Yu
