The VCL DB Tree Suite includes deprecated unbound and data-aware Tree View controls and editors implemented as wrappers for standard controls from the VCL component library shipped with Embarcadero RAD Studio® IDEs. DB Tree controls do not support many advanced features common to all DevExpress VCL controls, such as support for skins, high-DPI environments, multiple scrollbar types, etc.

Important

The VCL DB Tree Suite ships with DevExpress VCL products for backward compatibility only. DevExpress neither implements new features nor fixes bugs in deprecated products. We strongly recommend that you replace controls from the VCL DB Tree Suite with modern controls that implement similar functionality.

Tree View Controls

The Tree View controls allow you to display data in nodes with customizable captions and images. Users can drag-and-drop nodes to rearrange the tree structure and invoke in-place editors to rename these nodes.

Refer to the following class descriptions for details:

TdxTreeView

An unbound Tree View control.

Tip

The VCL ExpressEditors Library ships with an advanced Tree View control with support for skins.

TdxDBTreeView

A data-aware Tree View control.

Tip

The VCL Tree List Suite offers the skinnable TcxDBTreeList control that can display data as a tree, list, or a combination of both.

Tree View Editors

The Tree View editors combine an editor with a drop-down tree view.

Refer to the following class descriptions for details:

TdxTreeViewEdit | TdxDBTreeViewEdit

Unbound and data-aware controls that combine an edit box with an unbound drop-down Tree View control. Users can select an item from the Tree View.

TdxLookupTreeView | TdxDBLookupTreeView

Unbound and data-aware controls that combine an edit box with a data-aware drop-down Tree View control. Users can select an item from the Tree View or use it to edit fields that obtain data from other datasets.
