Try this.. in general regex format is "\w{min,max}" <form ID="Form1" name="Form1" runat=server><asp:ValidationSummary ShowSummary=True DisplayMode=SingleParagraph Enabled=True ID="vs" Runat=server /><asp:TextBox ID="txt" Runat=server Width="100"></asp:TextBox><asp:RegularExpressionValidator Runat=server Display=Dynamic ValidationExpression="\w{8,20}" ErrorMessage="invalid input" ControlToValidate="txt">*</asp:RegularExpressionValidator><br /><asp:button text="Submit" runat="server" ID="Button1"/></form>
