EHow to enable in-place editing in the WinForms tree List View (TreeListEditor)

3This example shows how to implement a custom ViewController that gets access to the TreeList control and makes it editable according tothe XtraTreeList documentation: WinForms Controls > Controls > Tree List > Feature Center > Data Editing TreeListOptionsBehavior.Editable Property TreeList.ShowingEditor Event TreeList.CellValueChanged Event

Take special note that special handling is required for the correct operation of editors for reference properties (e.g., a lookup filteringfunctionality requires obtaining the currently selected record).This is not a complete solution and you will need to modify and test this example code further in other scenarios according to your businessrequirements. For instance, if you require supporting ConditionalAppearance rules, consider using the code from the Q479878 ticket. If yourequire supporting member-level security permissions, consider extending this example by analogy withthe DevExpress.ExpressApp.Win.SystemModule.GridListEditorMemberLevelSecurityController class for GridListEditor.
