Public Property ValueMember As String
| Type | Description |
|---|---|
| String |
A String value that specifies the field name in a bound data source.

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