How to stop the Calendar after clicking button if it doesn't match the condition

[Blind]

Hi,
We use the RadDatePicker in our project. When the user click the RadDatePicker button to select the date, we will check if the condition is not matched, we need to cancel the action. And I have tried several ways, but they don't work.

 

function dateSelected(datepickerInstance, args) {

                args.CancelOpen = true;

                return false;

            }

<telerik:RadDatePicker runat="server" ID="rdp1">

    <DateInput ID="DateInput2" CausesValidation="True" runat="server"></DateInput>

    <Calendar ID="Calendar2" UseColumnHeadersAsSelectors="False" UseRowHeadersAsSelectors="False"   ViewSelectorText="x" runat="server"></Calendar>

    <DatePopupButton HoverImageUrl="" ImageUrl=""/>

    <ClientEvents OnPopupOpening="dateSelected" />

</telerik:RadDatePicker>

Please help me.

Thanks a lot!

Hello Blind,

You can achieve this in OnPopupOpening client-side event handler.

Javascript:

<script type="text/javascript">
  function dateSelected(datepickerInstance, args)
 {
 args.set_cancel(true);
 }
</script>

Also check the following documentation.
OnPopupOpening.

Thanks,
Shinu.
