Object | An object that specifies a collection of values displayed in the drop-down list. |
Remarks
The ItemsSource
collection contains values that users can select in the drop-down list. If this collection contains business objects, use the following properties to describe the business object’s data fields:
- DisplayMember — specifies the data field that contains values that are displayed in the drop-down list.
- ValueMember — specifies the data field that contains values that are actually assigned to cells.
Examples
The example below uses the ComboBoxColumn to display available values in the drop-down list when a user types in a cell.

In the example below, the ComboBoxColumn is bound to a data field that contains integer values. To display strings instead of integers in the drop-down list, the example uses a business object that combines strings with integers. The DisplayMember and ValueMember properties specify data fields that contain displayed strings and actual integer values.
