问题 I've looked at the answers to various questions, but haven't managed to map the content in the answers to the problem I'm attempting to solve. I've reduced it down to the following code (representative of the outcome I'm trying to achieve), and basically want to be able to render the Person.TitleId as its corresponding Title.TitleText when the row isn't being edited, and have the drop-down bound correctly so that it displays the TitleText s in the drop-down and writes the associated TitleId

问题 We have a Custom ComboBox working on a form that displays some shapes instead of text. To do that all I had to do was to override the OnDrawItem function and it displays what we want.
