Copy Paste a special character is accepting in Numeric Textbox

[Pathrudu]

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.

ASPX:

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

JavaScript:

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

Thanks,
Shinu.
