Multi Column ComboBox Control

ComboBoxEx control included with DotNetBar is drop-in replacement for standard ComboBox control. It adds Office like styling, additional item display options and most importantly multi-column display on its drop-down. Following image shows ComboBoxEx control with Office like styling:

Multi-column drop-down is built into the control and its activated when you set DataSource and DropDownColumns properties. Control will switch to multi-column display mode and it will display specified fields on drop-down:

Multi-column drop-down by default can be resized and also the close button for drop-down is displayed. Control will automatically create column header text based on field names, but they can be easily changed by setting DropDownColumnsHeaders property.
