Property Value
Type | Description |
---|---|
String | The data source field name. |
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.
Example
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.
