Key Features

TreeView for WinForms consists of the following key features:

• Node presentation

  C1Treeview allows users to implement node items as check-boxes, icons, multiple icons or text.

• Node editing

  You can edit a node simply by setting the AllowEditing property to True and pressing F2 after selecting the node. You can also cancel editing by pressing the Escape key.

• Drag and Drop

  TreeView enables users to drag nodes to new positions within the tree. Nodes can be dragged to a position below, above or into a child of other nodes.

• Load on Demand

  The load-on demand feature in TreeView helps reduce performance and memory costs when all the nodes are loaded at once. It gives a time delay in loading a node in a TreeView, prior to expanding a node.

• RTL Support

  The RTL support feature in TreeView allows the content to flow from right to left. TreeView provides support for RTL languages that render content from right to left of the page.

• Import Data

  TreeView allows users to export and import data to and from an XML files. For this purpose, the C1TreeView class provides the ReadXml and WriteXml methods.

• Unbound mode

  You can manually create a tree of nodes at design-time as well as run-time, thereby representing any data in a hierarchical form.

• Bound mode

  You can bind TreeView for WinForms to multiple tables with hierarchical relations to display hierarchical data. Also, you can bind the control to a self referencing data like a single list instead of multiple related lists.

• Themes support

  TreeView for WinForms uses C1ThemeController and offers theme support.

• Node selection and navigation

  TreeView supports both keyboard and mouse navigation of nodes. In addition, the control supports single and multiple node selection. You can select a node at both design-time and run-time. And you can select multiple nodes in a contiguous or a non-contiguous manner.

• Design-time support

  TreeView lets you access collection editors right from the design form using Smart tag and context menu. The collection editors allow you to add, remove nodes and columns without writing code.

• Node expansion

  You can expand either a single node or all nodes in the tree as per the requirement. You can also fully expand the tree in one go using the ExpandAll method at the TreeView level. And you can even prevent end-users from collapsing the expanded tree by cancelling the Collapsing event.

Note: The latest WinForms .NET Edition does not include rich design-time support yet. We will enhance it in future releases.
