LookUpEditBase.DisplayMember Property

Gets or sets a field name in the bound data source whose values are displayed by the editor. This is a dependency property.

Namespace: DevExpress.Xpf.Editors

Assembly: DevExpress.Xpf.Core.v23.2.dll

NuGet Package: DevExpress.Wpf.Core

Declaration

C#

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

VB.NET

<DefaultValue("")>
Public Property DisplayMember As String

Property Value

Type	Default	Description
String	String.Empty	A String value that specifies the data source field whose values are displayed by the editor.

Remarks

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

You can use the SubstituteDisplayFilter event to customize the filter applied by the LookUpEdit or ComboBoxEdit (for example, to filter data by an additional property).

Note

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