I have a requirement to be able to select multiple values. I have filtering enabled, but I only want the user to be able to select valid values and not enter custom data. My approach would be to clear any invalid data when the control loses focus. The documentation says the OnBlur event should be available but I only have OnChange and OnRead. I believe the functionality I want to mimic is similar to the ComboBox control AllowCustom="false" option. I'm using the latest version of the controls.
