I am having an issue and am on the very latest version of the controls where CommandBarTextBox elements placed in CommandBars do not fire the LostFocus events.
The following used to work, but since the last upgrade does not fire.
I have also tried the code below, but again nothing happens.
I could use the TextChanged event, but for filtering large datasets I do not want to filter for every keystroke, only when focus is changed.
These are being hooked in the constructor so the events should be firing.
