## Content



**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 <span data-popup-content="This property is available in C1TreeView classes of both \u003ca href=\u0022/componentone/docs/win/online-treeview/\u0022\u003e.NET Framework\u003c/a\u003e and \u003ca href=\u0022/componentone/docs/win/online-treeview/\u0022\u003e.NET\u003c/a\u003e assemblies." data-popup-title="AllowEditing" data-popup-theme="ui-tooltip-green qtip-green">AllowEditing</span> 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 <span data-popup-content="This method is available in C1TreeView classes of both \u003ca href=\u0022/componentone/docs/win/online-treeview/\u0022\u003e.NET Framework\u003c/a\u003e and \u003ca href=\u0022/componentone/docs/win/online-treeview/\u0022\u003e.NET\u003c/a\u003e assemblies." data-popup-title="ExpandAll" data-popup-theme="ui-tooltip-green qtip-green">ExpandAll</span> method at the TreeView level. And you can even prevent end-users from collapsing the expanded tree by cancelling the <span data-popup-content="This event is available in C1TreeView classes of both \u003ca href=\u0022/componentone/docs/win/online-treeview/\u0022\u003e.NET Framework\u003c/a\u003e and \u003ca href=\u0022/componentone/docs/win/online-treeview/\u0022\u003e.NET\u003c/a\u003e assemblies." data-popup-title="Collapsing" data-popup-theme="ui-tooltip-green qtip-green">Collapsing</span> event.
