Validate month

[Ivy]

Hi,

How to check and validate that the month selected from the second radmonthyear picker comes after the month selected from first radmonthyearpicker?

Thanks

Hi,

You can use ASP RequiredFieldValidator to ensure that both the fields are not left blank and an ASP CompareValidator to make sure that the second date selection comes after the first. Please have a look at the below mark up.

ASPX:

<asp:CompareValidator ID="dateCompareValidator" runat="server" ControlToValidate="RadMonthYearPicker2"
    ControlToCompare="RadMonthYearPicker1" Operator="GreaterThan" Type="Date" ErrorMessage="The second date must be after the first one.<br /><br />">
</asp:CompareValidator>

Thanks,
Princy.

Hi princy Is it possible to display an alert?

Hi,

If you want to display an alert, you can attach the OnDateSelected client event to the second RadMonthYearPicker and try the following JavaScript.

JavaScript:

<script type="text/javascript">
    function OnDateSelected(sender, args) {
        var Month1 = $find('<%=RadMonthYearPicker1.ClientID %>');
        var date1 = Month1.get_dateInput().get_selectedDate().getMonth();
        var date2 = sender.get_dateInput().get_selectedDate().getMonth();
        if (date2 < date1) {
            alert("The second date must be after the first one");
            sender.clear();
        }
    }
</script>

Thanks,
Princy.
