    I have set our ComboBoxes to ReadOnly as we don't want users entering foreign values. We also need the ability to clear a selected value with the Delete key. I have seen other threads on this, with the response saying to use the "Clear Selection" button.

    As our forms are mainly used by Data Entry clerks, they are keyboard driven users. What they need is to be able to tab from field to field and quickly delete existing values. This should be achieved with the Del or Backspace key. Having to switch to a mouse or arrow down to a Clear Selection button adds too many actions to what should be a simple work flow.

    Is there a possibility to attach the "Clear Selection" function to the users Del key?

    Hello Murray,

    Thank you for contacting us.

    You can handle the KeyDown event of the ComboBox and clear the value if it is a Delete key, for example:

    private void radComboBox_KeyDown(object sender, KeyEventArgs e) 
               if(e.Key == Key.Delete) 
                   (sender as RadComboBox).SelectedItem = null

    Hope this helps. If you have any other questions please let us know.
