General
  • Load on demand (MSDN-style) for larger structures
    In case your treeview has a large number of nodes, you can load only the visible ones. When the user requests a child node it is loaded "on demand", just like the MSDN contents menu.
  • Drag-and-drop functionality
    This feature is unique to r.a.d.treeview and allows you to easily rearrange its structure by simple drag-and-drops of nodes or complete branches. This will automatically fire a server-event (postback) that receives instances to both source and destination nodes as EventArgs.
  • Multiple node selection (Ctrl + select)
    You can select more than one node by holding down the CTRL key while clicking on a node. Upon postback you can retrieve all selected nodes using an API method.
  • Tree-view ComboBox mode
    Another unique feature of the r.a.d.treeview is the ability for implementation of treeview combobox, similar to the Custom Links drop-down of the r.a.d.editor.
  • Full support for images and CSS
    You can easily blend r.a.d.treeview in the interface of your web-application using images and CSS. You can control the appearance of every single node or format groups of nodes according to their state (i.e. NodeOver, NodeSelected, NodeDisabled).
  • Auto SQL binding from ADO.NET Dataset
    Seamless integration with SQL technology makes r.a.d.treeview the tool for your dynamic web-site or application. Populate your treeviews directly from your database, reusing queries and cutting on updates. Furthermore, you can use the method for auto SQL binding and instantly populate your structure from an ADO.NET Dataset.
  • Cross-frame support
    Every node has a Target attribute which makes r.a.d.treeview compatible for every frame scenario ("_blank" is supported as well).
  • Check-box support
    r.a.d.treeview allows you to easily add a checkbox to each Node. You can also fine tune which Nodes display checkboxes (i.e. root Nodes, Nodes with child Nodes, child Nodes only, etc.) At runtime, you can get a collection of the checked nodes using an API method.
  • API for dynamic add/delete/disable of nodes
    r.a.d.treeview provides a comprehensive set of API methods for programmatic control at run-time: add, delete, enable, disable, check, uncheck, etc..
  • Multiple instances on a single page
    Challenged by a navigational task? r.a.d.treeview allows the use of multiple treeviews per page, reusing a single code library for faster development and speed on the client.
  • Control over the initial node state - expanded/collapsed
    Creating intuitive hierarchical navigation has never been easier thanks to the r.a.d.treeview's ability to specify the initial state (expanded/collapsed) of a given node or of the whole tree altogether.
  • Retaining of the scroll position between postbacks
  • In case you have a large treeview structure the component can be set to retain its scroll position between postbacks, so that the current node is always visible.
