    The RadDatePicker has default validation for any invalid date. It is working fine. But ,this does not work for me. For a invalid date , current as is implementation keeps the focus on the RadDatePicker control with a Warning image (like a triangle).

    My requirement is to put the error message just below the RadDatePicker control, Not inside the control. I want to get rid of the image. Is there way I can disable the default behaviour and implement the custom behaviour using a javascript ?

    Hello Deba,

    You can attach the client event OnError and handle the error there. Here is a sample code to achieve the same.

    <telerik:RadDatePicker ID="RadDatePicker1" runat="server" Width="150px" AutoPostBack="false">
        <DateInput DateFormat="dd MMM yyyy" ClientEvents-OnError="ShowMessage">
    <asp:Label ID="Label1" runat="server" Text=""></asp:Label>

    function ShowMessage()
        document.getElementById("Label1").innerText="InvalidDate!!";//setting label text

    You can hide the default alert icon by overriding the default CSS like below.
               background-image:none !important;
