Hello Eva,

Here is how to do it:

<telerik:RadNumericTextBox ID="RadNumericTextBox1" runat="server" > 
    <ClientEvents OnKeyPress="RadNumericTextBox_KeyPress" /> 
</telerik:RadNumericTextBox> 
 
<script type="text/javascript"
 
function RadNumericTextBox_KeyPress(sender, args) 
    if (args.get_keyCharacter() == ".") 
    { 
        args.set_cancel(true); 
        var eventArgs = new Telerik.Web.UI.InputErrorEventArgs( 
            Telerik.Web.UI.InputErrorReason.ParseError, 
            sender.get_textBoxValue(), 
            args.get_keyCode(), 
            args.get_keyCharacter() 
        ); 
        sender.raise_error(eventArgs); 
    } 
 
</script> 


The Javascript code, which comes after "args.set_cancel(true);" makes the numeric textbox flash for a moment, indicating that you are trying to enter an invalid character.


All the best,
