Third party controls integration

To edit data, the treeview uses your operation system`s controls, which may differ from those used in your application.

To fix this problem, Flexible TreeView allows you to change any control that is used in the treeview either to edit or display data (for example, scroll bars).

Change edit controls

Flexible TreeView uses many controls to edit data (edit controls) inside a node control. You can completely or partially override those controls, both in global or personal themes, by using the EditorRepository property.
There are three levels of overriding:

As stated above, you can use third party controls by using deployed extensions from the Customization folder. To do that, include a source code file with this extension and use the code below.

Example:

// replace the numeric editor for one treeview by a control from DevExpress.
tree.EditorRepository.NumericEditor = new DevExpressNumeric();
 
// replace the text editor for one treeview by a control from DevComponents.
tree.EditorRepository.TextBoxEditor = new DevComponentsTextBox();
 
// replace the text editor for all treeviews with global theme by own control.
ThemeManager.ActiveManager.EditorRepository.TextBoxEditor = new MyTextBoxEditor();
 
// replace the text editor for all treeviews with the same theme manager.
ThemeManagerOffice2007Blue tm = new ThemeManagerOffice2007Blue();
tm.EditorRepository.TextBoxEditor = new MyTextBoxEditorControl();
tree.ThemeManager = tm;
secondTree.ThemeManager = tm;

Scroll bars

By default, Flexible TreeView uses a standard OS`s scroll bar control, but you can replace it using the VertScrollBar and HorzScrollBar treeview properties. You can use either deployed extensions from the Customization/ScrollBars folder, or use your own by implementing the IScrollBarControl interface. Replacing scroll bars is similar to replacing edit controls as stated above.

Use custom edit controls

To create an extension for using your own control inside Flexible TreeView, you need to implement one of these interfaces, depending on the data type that your control supports and can edit:

You can attach you control`s extension to the treeview as stated above.
