 # XAF WinForms - How to use a custom Lookup Property Editor control for reference properties
 
-> **Note**  
-> The description of this example is currently under construction and may not match the code in the example. We are currently working to provide you with up-to-date content.
-
-## Scenario
+This example demonstrates a simple drop-down editor for reference properties. The editor contains **Open**, **Add**, and **Clear** buttons.

 ## Implementation Details
 
-1. The _Editors.Win_ module implements a reusable `LookupPropertyEditorEx` class. This is an XAF Property Editor that can be used for reference properties instead of the standard `LookupPropertyEditor` in WinForms XAF applications.
+The [LookupPropertyEditorEx.cs](./CS/EFCore/Editors.Win/LookupPropertyEditorEx.cs) file contains the reusable `LookupPropertyEditorEx` class. This Property Editor can be used for reference properties instead of the standard `LookupPropertyEditor` in WinForms XAF applications.
 
-2. The `LookUpEditEx` and `RepositoryItemLookUpEditEx` classes implement a control for this Property Editor. This control is inherited from the `LookUpEdit` class and extends it with additional features required for the Property Editor.
+The `LookUpEditEx` and `RepositoryItemLookUpEditEx` classes implement a control for this Property Editor. The control extends the  [LookUpEdit](https://docs.devexpress.com/WindowsForms/DevExpress.XtraEditors.LookUpEdit) class with additional features.
 
-## Additional Information
-
-1. From this example, you need use only one assembly (the _WinSolution_ from the example is just a demo application, and it has no relation to the solution): `Editors.Win.dll`.
-   
-   Since this is a regular XAF module, you should add this module to your application to be able to use its features. In case of standard modules, you add them from the Toolbox via the Application or Module designer. Since we deal with a custom module, you should add this into the Toolbox manually. For additional information, refer to the following article: [To add a tool to the toolbox](https://learn.microsoft.com/en-us/visualstudio/modeling/customizing-tools-and-the-toolbox?view=vs-2022#to-add-a-tool-to-the-toolbox).
-   
-   Alternatively, you can take the source code and include it in your solution.
+> **Note**  
+> To further research how the lookup property editor works, you can look at its source code in the following file:  
+> _C:\Program Files\DevExpress xx.x\Components\Sources\DevExpress.ExpressApp\DevExpress.ExpressApp.Win\Editors\LookupPropertyEditor.cs_
 
-2. The `LookupPropertyEditorEx` is set as default for all lookup properties in the application.
-   
-   If you want to change this, then invoke the Model Editor for the Windows Forms application project or module, and change the **EditorType** property of the **DetailViewItems** | **PropertyEditors** | **LookupProperty** node. Or change the **PropertyEditorType** property for a class member, List View column or Detail View item nodes individually.
