    Okay, this is a strange one, but the boss is asking for it....

    He doesn't want to display decimals in a RadNumericTextBox if the decimal portion equals .00.

    For example, if the value is 123.44, the texbox should display


    However, if the number is 123.00 then the textbox should display


    Does that make any sense? Does anyone have any idea how this could be done without a TON of "if" coding?

    Hello Ken,

    You can achieve the described behavior by setting  NumberFormat.AllowRounding  to "false". If you don't want to disable rounding, then you will have to use some custom Javascript. Subscribe to the ValueChanged and Blur client events. In the event handler, you can access the formatted value inside the textbox with sender._textBoxElement.value.

    <telerik:RadNumericTextBox ID="RNTB1" runat="server">
        <ClientEvents OnBlur="RemoveZeros" OnValueChanged="RemoveZeros" />
    <script type="text/javascript">
    function RemoveZeros(sender, args)
        var tbValue = sender._textBoxElement.value;
        if (tbValue.indexOf(".00") != -1)
            sender._textBoxElement.value = tbValue.substr(0, tbValue.indexOf(".00"));
