I think you should use Regular Expression,
i.e

XML

<asp:TextBox ID="TextBox1" runat="server"></asp:TextBox>
<asp:RegularExpressionValidator
        id="RegularExpressionValidator1"
        runat="server"
        ControlToValidate="TextBox1"
        ValidationExpression="^[0-9]{1,6}(\.[0-9]{0,2})?$"
        ErrorMessage="Invalid Number" />Invalid number</asp:RegularExpressionValidator>
