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.v25.2.dll
NuGet Package : DevExpress.Wpf.Core
[DefaultValue("")]
public string DisplayMember { get; set; }
<DefaultValue("")>
Public Property DisplayMember As String
| Type | Default | Description |
|---|---|---|
| String | String.Empty |
A String value that specifies the data source field whose values are displayed by the editor.
|
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.
The following code snippets (auto-collected from DevExpress Examples) contain references to the DisplayMember property.
Note
The algorithm used to collect these code examples remains a work in progress. Accordingly, the links and snippets below may produce inaccurate results. If you encounter an issue with code examples below, please use the feedback form on this page to report the issue.
