Use the control's Footer property to specify content that should appear in the Footer area of the dropdown.
Control how the dropdown list is filtered as the user types text into the control's text area.
Text, Checkbox, Image, and Date column support.
Use the Multi-Column Combo as a cell type in a grid.
