// This sample implements two different custom cell controls. // // The first is a DropDownForm cell. This cell control drops // a Windows Forms Form holding a CheckedListBox and two buttons. // It behaves in a modal way, meaning the form captures the input // focus until the user explicitly closes it. This cell derives from // GridDtaticCellRenderer and GridStaticCellModel. // // The second custom cell control is a DropDownUserControl cell. // This cell drops a UserControl holding a CheckedListBox and two // buttons. This cell ties into the grid''s popup architecture to allow // the usercontrol to behave like a combobox in a modaless way. It does so // by being derived from GridDropDownCellRenderer and GridDropDownCellModel.
