How to add a custom button into LookupPropertyEditor to edit the currently selected record

To open a detail view for the currently selected object LookupPropertyEditor, you can press Ctrl+Shift while clicking the editor.
Another way is to implement your LookupPropertyEditor's descendant, which will provide the specific functionality you need.
LookupPropertyEditor is represented in a detail view by the LookUpEdit control, which allows various customizations. You can customize it by adding a special button that invokes a detail view for the selected object or performs any other actions.
