The ASPxTreeList is a multi-purpose data visualization control that can display information as a tree or grid - either in data-bound or unbound mode.
The ASPxTreeList provides the following key features
- Data Binding
- Summary Computation
- Data Paging
- Node Selection
- Appearance Customization
- Templates, etc.
Note
The ASPxTreeList control provides you with a comprehensive client-side functionality implemented using JavaScript code:
- The control’s client-side equivalent is represented by the ASPxClientTreeList object.
- On the client side, the client object can be accessed directly by the name specified via the ASPxTreeList.ClientInstanceName property.
- The available client events can be accessed by using the ASPxTreeList.ClientSideEvents property.
The client-side API is always available for this control.
