Question

I want to use RangeValidator to validate percentage value. For that I set minimum value as 0.0 and maximum value to 100.00, but its not working. I tried using minimum value as 0% and maximum values as 100% but still not working.

Here is some code:

<asp:RangeValidator ID="percentageRangeValidator" runat="server"
   ControlToValidate="percentageBox" Display="Dynamic" 
   ErrorMessage="Invalid Percentage" 
   MaximumValue="100.00" MinimumValue="0.00">*</asp:RangeValidator> 

What’s wrong in my method.

Answer 1

You need to specify the type of the value Type="Double":

<asp:RangeValidator ID="percentageRangeValidator" runat="server"
    ControlToValidate="percentageBox" Display="Dynamic" 
    ErrorMessage="Invalid Percentage" MaximumValue="100.00" MinimumValue="0.00" 
    Type="Double">*</asp:RangeValidator>
