Currency Format Lost after Cancel Event

[License]

I have some Numeric Textboxes where I am using the OnValueChanging client event to do some validation and when I utilize the eventArgs.set_cancel(true) function, the value is reverted back to the old value, however the currency format is lost when I exit the field. If I reenter the field and exit again, the dollar sign will display properly.

 

Here is a sample of the script: 

function onValueChanging(sender, eventArgs) {
    var value = eventArgs.get_newValue();

    var txtTest = $find("<%= txtTest.ClientID %>");

    if ((value < sender.get_minValue()) || (value > txtTest.get_value())) {
        alert('Value must be a non-negative number and cannot exceed txtTest');
        eventArgs.set_cancel(true);
    }
}

Hello Robert,

Thank you for reporting this issue with the RadNumericTextBox.

I will forward the problem to our developers team, so they could further investigate it. As a temporary workaround you can use the following code that forces the control to format the value:

<telerik:RadCodeBlock ID="RadCodeBlock1" runat="server">
    <script type="text/javascript">
        function onValueChanging(sender, eventArgs) {
            var value = eventArgs.get_newValue();

            var txtTest = $find("<%= txtTest.ClientID %>");

            if ((value < sender.get_minValue()) || (value > txtTest.get_value())) {
                alert('Value must be a non-negative number and cannot exceed txtTest');
                eventArgs.set_cancel(true);
                setTimeout(function () {
                    sender.focus();
                    sender.blur();
                })
            }
        }
    </script>
</telerik:RadCodeBlock>

<telerik:RadNumericTextBox runat="server" ID="txtTest" Value="5"></telerik:RadNumericTextBox>

<telerik:RadNumericTextBox runat="server" Type="Currency" MinValue="0" ClientEvents-OnValueChanging="onValueChanging"></telerik:RadNumericTextBox>

For bringing the issue to our attention you will find your Telerik Points updated.
