  • Dynamic (depends on the content) or static node height support. It allows applying outstanding visual effects by using our unique expandable node controls.
  • The child node's style and behavior can be inherited from the parent node.
  • Soft selection mode - state-of-the-art feature, which allows you to view additional node content when you mouse hover over a node, without selecting a node, which appreciably speeds up data viewing.
  • On-demand node population enables populating child nodes only when the parent node is expanded.
  • Different node selection modes:
    1. Single - allows to select only one node at a time.
    2. Multi - allows to select multiple nodes.
    3. Multi on the same level - allows to select many nodes on the same level.
    4. Multi within the same parent - allows to select only sibling nodes within the common parent.
  • Different node highlight modes:
    1. FullRow - highlights the entire node row.
    2. Partial - highlights only node controls.
    3. ContentOnly - highlights node controls except non-interactive node controls.
  • Single expand mode automatically expands the focused node and collapses all other nodes in the treeview. This enables you to quickly view only the data you need without the clutter of other nodes.
  • Always expanded mode - keeps all nodes expanded for quick navigation.
  • Different node styles:
    1. Selectable - defines whether the node can be selected.
    2. Hoverable - highlights the node under the mouse cursor.
    3. Enabled - whether the node can interact with the end user.
    4. AllowExpand - whether the node can be expanded.
    5. AllowCollapse - whether the node can be collapsed.
  • Text hot tracking support.
  • Node state image support - assign different icons for each node state, such as expanded and collapsed, to enhance the visual representation of your treeview.

Node Controls
  • Unlimited node controls quantity for viewing and editing data in the treeview. No more ugly nodes with text and icons only.
  • Built-in node control types to show different types of your data:
    1. PlusMinus - allows you to move the plus-minus sign into any column.
    2. TextBox - displays text data.
    3. CheckBox - shows a check box. Supports three or two check states and different interactive check modes (the parent node's check state is auto-calculated based on the children nodes' check state).
    4. RadioButton - shows a radio button. Can be grouped within the parent node.
    5. Image - displays an image. Allows you to show an eye-catching image animation.
    6. ComboBox - shows a combo box.
    7. Numeric - displays numeric values.
    8. Expandable text box (read below).
    9. Expandable panel (read below).
    10. Control container - hosts any custom control inside a node. Easily customize exact node states when your custom control will be visible.
    11. Expandable control container - hosts any custom control in the expandable area of an expandable node control. I.e. display you custom control only when the mouse hovers over the node.
    12. Color picker- allows you to select a color or color gradient from a treeview without writing a single line of code.
    13. Link - allows you to insert a clickable hyperlink.
    14. PaintBox - allows you to paint any custom content in the node.
    15. Popup container- allows you to show any custom content in the popup. So treeview stays clear and understandable while informative for separate nodes.
    16. Separator - shows the separator horizontal line in the node.
    17. ProgressBar - allows you to show the progress bar in the treeview node.
  • Expandable text box - allows you to show only a title text when the node is not focused and the title text plus a description text when the node is focused or under the mouse cursor (when the soft selection is enabled). That allows you to not overload the treeview with information, to be intuitive and understandable, while at the same time providing more information on the selected node.
  • Expandable panel - identical to the Expandable text box above, but it allows you to display custom content (static or dynamic) in the expandable area in an impressive and very professional way.
  • In-place node data editing with the ability to deny the editing for a particular node control.
  • View static or dynamic content in the node. You can create flexible, informative, and dynamic treeview.
  • Easy replacement of all edit controls with third-party vendor controls or your own to give your application a personalized, consistent look. No more messy applications with two or more control styles.
  • Dynamic or static filtering of node control visibility for every node or column that allows you to display only the data you need.
  • Ability to exclude any node control from the sorting algorithm or write own algorithm.
  • Node control can fill all the available space of a column or whole treeview to show large content.
  • Node control can be shown on multiple levels to create stunning UX.
  • You can easily control the visibility of every node control and for every node, show a tooltip for each node control, and apply content alignment and padding.
  • Column controls for faster user productivity and better user experience.
  • Auto-fit columns within treeview.
  • Switch the column visibility with a single property.
  • Show or hide the columns header.
  • Node control can span the specified columns count to provide a professional UI.
