>Moving or resizing a column does fire the Move or Resize Event of the column, but that's really all I can locate. In my situation some other objects on the form need a refresh in both cases, but their Refresh() is not triggered. I could add some code ( e.g. thisform.refresh() ) in the Move() and Resize() method of each column, but that can hardly be called a fundamental solution.
