I have a listbox with a popup menu when user clicks a canvas item (drawn button icon) in column 4. Prior to the user 'clicking', I'd like the canvas item to do 'something' visually on hover - similar to how a weblink auto-underlines on mouse over. Is there a simple way to do this with an event handler? I have been experimenting with MouseMove (and MouseEnter / MouseExit) to no avail. Was just going for simple text underline to start with (maybe utilizing ListBox.CellUnderline?) . Sorry if this has been answered a billion times, just haven't been able to find the answer in the forum.
