Monika,

The property is ValidationExpression. It is used by setting it equal to a regular expression, which in your case will stop the user from entering zero and any other character. Your regular expression will allow only positive integers. You can scour the Internet for regular expressions to stick into the ValidateExpression property.

Example:

Code:

<asp:RegularExpressionValidator id="RegularExpressionValidator1" runat="server"
            ControlToValidate="TextBox1"
            ValidationExpression="^\d{5}$"
            Display="Static"
            Font-Name="verdana" 
            Font-Size="10pt">
               Zip code must be 5 numeric digits
        </asp:RegularExpressionValidator>
