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>
