I want to set a Range Validator on a TextBox to prevent someone from entering max and min value greater than is available in DB table.
Both min and max Value saved in DB has datatype Double.
<asp:TextBox ID="WaterLvl" runat="server" MaxLength="10"></asp:TextBox>
<asp:RangeValidator ID="RangeValidator1" runat="server" MaximumValue=" " MinimumValue=" " Type="Double" Text="Value out of range" ErrorMessage="Value out of range" ControlToValidate="WaterLvl" ForeColor="Red"></asp:RangeValidator>
Please reply how to achieve that.
