LookUpEditBase.ValueMember Property

Gets or sets a field name in the bound data source, whose values are assigned to item values. This is a dependency property.

Namespace: DevExpress.Xpf.Editors

Assembly: DevExpress.Xpf.Core.v22.2.dll

NuGet Package: DevExpress.Wpf.Core

Declaration

[DefaultValue("")]
public string ValueMember { get; set; }

Property Value

Type Default Description
String String.Empty

A String value that specifies the field name in a bound data source.

Remarks

To bind the editor to a data source, use its LookUpEditBase.ItemsSource property. The LookUpEditBase.DisplayMember and LookUpEditBase.ValueMember properties specify the field names in a data source that supply display strings and item values, respectively.

Note

The ValueMember property should refer to a data property that contains unique values.

If the ValueMember property is not specified, the editor’s BaseEdit.EditValue property returns the entire data object that corresponds to the selected item.

Note

When the DisplayMember and ValueMember properties are specified, the ComboBoxEdit allows users to enter only the values from its ItemsSource.

The following code snippets (auto-collected from DevExpress Examples) contain references to the ValueMember property.
