Gets or sets the path of the property to use as the actual value for the items in the control. This is a bindable property.
Namespace: DevExpress.Maui.Editors
Assembly: DevExpress.Maui.Editors.dll
NuGet Package: DevExpress.Maui.Editors
Declaration
public string ValueMember { get; set; }
Property Value
Type | Description |
---|---|
String | The single property name of the bound data source, or a hierarchy of period-delimited property names that resolves to a property name of the final data-bound object. |
Remarks
You can bind the ItemsSource property to a collection of custom objects. Use the DisplayMember and ValueMember properties to specify the names of data source fields that contain captions for items in the drop-down list and their values. To obtain the selected item’s value, you can use the SelectedValue property.
Example
The code below shows how to bind a ComboBoxEdit to a list of business objects. A Person
object exposes the Name
, Age
, and Location
data fields. The DisplayMember property is set to Name
, and the ValueMember
is set to Age
. As a result, the editor shows persons’ names in the drop-down list but the SelectedValue property returns the selected person’s age.
