Hi,

Change your code to as follows.

XML

<asp:RangeValidator runat="server" ID="RangeValidator6" ForeColor="Red" ControlToValidate="txt_TotalArea" Type="Double" MinimumValue="0" MaximumValue="40" ErrorMessage="Please enter the Gunta value between 0 and 40!" />

<asp:RegularExpressionValidator id="RegularExpressionValidator8" runat="server" ControlToValidate="txt_TotalArea" ForeColor="Red" ValidationExpression="(^[0-9]\d{0,9}(\.\d{1,5})?%?$)" ErrorMessage=" Allowed only 5 Decimal Places." />

Thanks,
