  • Powerful Databinding

    Binding Telerik TreeView for Windows Forms is as simple as setting a single property. The control can be bound to any object that implements IList, IListSource or IBindingList. This includes generic lists and BindingSource as well.
  • 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.

  • Editing

    RadTreeView supports editing of its nodes. By default, a textbox editor appears for your nodes’ data, but you can easily employ one of the other built-in RadTreeView editors depending on your exact scenario.

  • Filtering, Sorting, Rich API

    RadTreeView comes with an easy to use built-in filtering and sorting mechanisms - all you need to do is wire the exposed event for each, and the TreeView will do these operations with ease, and on the fly.

    In addition, it offers 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.

  • 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.

  • Search As You Type

    Allow your end-users to navigate through long lists with the familiar search-as-you-type keyboard navigation function.

  • RadBreadCrumb is designed specifically to help users with RadTreeView navigation. Breadcrumbs are most appropriate when your data has a deep hierarchical structure with many levels. When you select a node in RadTreeView, the breadcrumb component will show the path to the node as a sequence of drop-down buttons. It will also enable you to navigate in the tree view by selecting a specific item.

The Composite UI Application Block is designed to help in building complex, enterprise-ready Windows Forms solutions by providing a proven architecture and implementation, based on common patterns found in line-of-business front-end applications.

  • 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.
