Things you can do with a multicolumn ListBox or ComboBox

To control the column widths of a multicolumn ListBox or ComboBox, you can specify the width, in points, for all the columns in the ColumnWidths property. Specifying zero for a specific column hides that column of information.

If you want to hide all but one column of a ListBox or ComboBox from the user, you can identify the column of information to appear by using the TextColumn property.

Similarly, you can control which column of values is used for the control when the user makes a selection by specifying the column number in the BoundColumn property.
