Question

I am using a custom validator to compare value in two text box. This is comparing the values fine. But it says ‘025’ and ’25’ are different.. can this do a float comparision.

the custom validator i am using is

<asp:CompareValidator id='compval' runat='server' ControlToValidate='txtBox1'                     ErrorMessage='There values are not equal.'                     Enabled='False' ControlToCompare='txtBox2'>*</asp:CompareValidator></TD> 

Please let me know if this is possible.

Answer 1

Use System.Double.Parse(value) to convert both to a floating point number, and compare those numbers.

You can also use TryParse if you don’t want to handle exceptions if the value is not a valid floating point number.
