LookUpEditSettingsBase.ValueMember Property

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

Namespace: DevExpress.Xpf.Editors.Settings

Assembly: DevExpress.Xpf.Core.v24.2.dll

NuGet Package: DevExpress.Wpf.Core

Declaration

C#

public string ValueMember { get; set; }

VB.NET

Public Property ValueMember As String

Property Value

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

Remarks

To bind the editor to a data source, use its LookUpEditSettingsBase.ItemsSource property. The LookUpEditSettingsBase.DisplayMember and LookUpEditSettingsBase.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.
