Drag and Drop Behavior
With the Telerik Windows Forms TreeView you can expand your winforms application capabilities through the rich drag & drop functionality. You can easily perform the following drag and drop operations:
- Drag and drop nodes within the same RadTreeView
- Drag and drop between several RadTreeViews
- Determine the node position - within, above or below a given node by using the intuitive position indicator
- Drop nodes in other elements such as textboxes
- Auto-scroll on drag - when dragging a node to a part of the treeview which is hidden, the control will scroll up/down to that part automatically
- Expand on drop - when dragging a node to a collapsed node, the control will automatically expand the collapsed node
- Drag-and-drop for specific nodes only - you can fine-tune the drag and/or drop behavior of the treeview by setting only specific nodes to support drag/drop actions.

Context Menu with Styling Capabilities

Expand the functionality of Telerik TreeView by adding context menus to any tree node by using Telerik's Menu for Windows Forms. For extra flexibility, you can have different context menus for each tree node. Each context menu is fully customizable and skinnable.

Checkbox and TriState Checkboxes Support

Checkboxes with checked, unchecked, and partial states are fully supported within the Telerik Windows Forms TreeView. Checkbox states can also be managed from the code behind to facilitate higher interactivity of your treeviews.

Telerik TreeView also supports checking/unchecking all subnodes whenever the parent node is checked/unchecked - a very convenient and expected behavior of every treeview. This spares the effort for repetitive clicking that may even be impossible for larger structures.

Rich API

Telerik TreeView for Windows Forms has a rich API and comprehensive set of events guaranteeing full control over various functions. You can easily add/delete/update items at run time and all the changes will be persisted. In addition, creating intuitive hierarchical navigation has never been easier thanks to the RadTreeView's ability to specify the initial state (expanded/collapsed) of a given node or of the whole tree.

Right-to-Left Language and Localization Support

Due to business globalization, the need for multi-lingual applications is a must. Telerik Windows Forms TreeView supports RTL languages, such as Hebrew and Arabic:

Full localization of its strings is also supported. See Localization and Right-to-Left Support for the full list of Telerik Windows Forms controls supporting RTL languages.

Animations

As with all controls built on top of the Telerik Presentation Framework (TPF), RadTreeView supports a variety of expand animation styles for a great user experience. You can select among predefined animations and further customize them with any settings relevant for your scenario.

Appearance

The control is shipped with a rich set of themes that allow you to easily build slick interfaces with the look-and-feel of Windows Vista, Office 2007, Outlook, etc. The themes can be easily switched using a single property.

In addition to the built-in themes, all RadControls for WinForms come with a feature we call Theme Color Blending, which allows for tweaking the color scheme of a theme, without the need to redo the theme from scratch. The updated color scheme is applied to all Telerik WinForms controls that you are using in your application for a fresh new look. Or you can build a new theme from scratch to fit your exact visual demands by using the Visual Style Builder productivity tool.

Telerik TreeView is also capable of displaying rich text formatting by using standard HTML tags, such as <i>, <b>, and <u>. This is supported on a framework level.

Full Keyboard Support

Telerik Windows Forms TreeView can be fully navigated using the keyboard. You can focus on a treeview with a predefined Alt+Key combination, navigate through the nodes, expand/collapse, select, and check/uncheck nodes. In-Place Editing is also supported by pressing F2.
