Hi sudheer,

You can use the DateInput's KeyPress client-side event handler:

ASPX

<telerik:RadDatePicker ID="RadDatePicker1" runat="server">
    <DateInput runat="server" ClientEvents-OnKeyPress="KeyPress" />
</telerik:RadDatePicker>

Javascrript

function KeyPress(sender, args)
{
    var re = /^[0-9\-\:\/]$/;
    args.set_cancel(!re.test(args.get_keyCharacter()));
}

The above code will allow numbers, dashes, colons and slashes. You can remove the unnecessary symbols, according to your requirements.
