RadCalendar : Accept only numerals in the editing box

[Udaya Kumar]

Dear Telerik Team,

I just wonder ,is there any way to make the users to enter only the numeric values in the edit box of the calendar ? currently it accepts the alphabets as well.

Hi Udaya,

I tried following approach in order to prevent alphabets in input of RadDatePicker.

ASPX:

<telerik:RadDatePicker ID="datepicker2" runat="server" Culture="English (United States)">
    <DateInput ID="DateInputSentQcDate" DateFormat="MM/dd/yyyy" Style="color: Navy" runat="server">
        <ClientEvents OnKeyPress="OnKeyPress" />
    </DateInput>
</telerik:RadDatePicker>

JavaScript:

<script type="text/javascript">
    function OnKeyPress(sender, eventArgs) {
        var c = eventArgs.get_keyCode();
        if (!((c < 65) || (c > 90 && c < 97) || (c > 122)))
            eventArgs.set_cancel(true);
    }
</script>
