    Trying to Copy Paste date format(01/01/2013) is accepting in numeric text box. after moving out of that control it is displaying (01012013). But when i moving out of the control, i need to display a warning message, please enter valid numeric values instead of removing special character.

    Hi Pathrudu,

    Please check the following code snippet which  restrict user from entering special character in the  RadNumericTextBox.

    <telerik:RadNumericTextBox ID="RadNumericTextBox1" runat="server" ClientEvents-OnValueChanging="OnValueChanging">

    <script type="text/javascript">
        function OnValueChanging(sender, args) {
            var numerictxtbox = document.getElementById('<%=RadNumericTextBox1.ClientID %>');
            var txtboxvalue = numerictxtbox.value;
            if (!txtboxvalue.match("^[0-9]+$")) {
                alert("Please enter valid input!");
