I've got a "simple" app (Windows Forms) in which I'd like to have a ComboBox (takes up one line) with a dropdown list (display multiple lines), but I'd like to be able to select multiple items (like a ListBox).
I've tried to "fake it" by designing a control with a ComboBox (with no entries) and an invisible ListBox with multiple lines that becomes visible when the ComboBox is clicked. This _almost_ works but other items on the form (Labels, RadioBoxes, etc.) show through the ListBox when it is made visible.
Any help would be appreciated.
