    If a user deletes (either with the delete key or backspacing) the custom text, the event "onclienttextchange" does not fire.  Is this by design?

    Hi Jason Parrish,

    Yes. You are right that backspacing does not fire OnClientTextChange event. To catch when backspace is pressed you may use OnClientKeyPressing event for example:

    <telerik:RadComboBox ID="RadComboBox1" runat="server" OnClientTextChange="OnClientTextChange"
                OnClientKeyPressing="HandleKeyPress" AllowCustomText="true">

    In the Javascript function below 8 is the ASCII code of the Backspace button.

    1.function HandleKeyPress(sender, eventArgs) {
    2.           if (eventArgs.get_domEvent().keyCode == 8) {
    3.               alert("Backspace is pressed");
    4.           }
    5.       }

    I've attached the full code as a .zip file.

    If you have more questions, please let me know.
