ASPNET Custom Validtor Error Message is not displaying

I have aspnet application with custom validator using java script. I have to compare 2 dates in textboxes (txtbeginDate ,txtEndDate). I wrote my java script as

Java Script:
function DateCompareClient(oSrc, args)
 {
    var begindt = new Date(document.getElementById('txtBeginDate').value);
    var endDt = new Date(document.getElementById('txtEndDate').value);
    if (begindt < endDt) {
        args.valid = true;
        return;
    }
    args.valid = false;
    return;
}


                                           <asp:CustomValidator
                                                    ID="Customvalidator3" runat="server"
                                                    ControlToValidate="txtEndDate" ErrorMessage="End Date must be later than Begin Date"
                                                    EnableClientScript="true" ClientValidationFunction="DateCompareClient" 
                                                    >*</asp:CustomValidator></td>

Now , script is runing fine, but its not displaying error message. if condition is false , it should display error , which is not happening?

What you are trying to do can be accomplished without any javascript, called the Compare Validator 

 <asp:CompareValidator id="compareStartAndEndDates" 
                ControlToValidate="txtEndDate" 
                ControlToCompare="txtBeginDate" 
                Operator="LessThan"
                Text="End Date must be after Begin Date" 
                Type="Date"
                runat="server"/>

I suspect that your validator is never actually firing. Stick an alert() in your javascript to test that.

On your textboxes, you want to make sure they are set to AutoPostBack="true" so that when the user moves away from that field, the validator kicks in. You might also need CausesValidation="true"
