Flexible Data Binding

ASPxTreeList can display information as a tree or grid - either in a data-bound or unbound mode. It supports any standard data source type including: SqlDataSource, ObjectDataSource, XmlDataSource, AccessDataSource, SiteMapDataSource. ASPxTreeList can also be bound to any object that represents a tree structure, and can also manually create a tree in code.

To ensure that your data can be easily displayed within ASPxTreeList, we provide the following data binding options:

Unbound Mode

You can build the desired tree structure in code using specially designed methods.

Run Demo

Bind to a Hierarchical Data Source

If you bind to a hierarchical data source, such as XmlDataSource or SiteMapDataSource, the control will automatically build a corresponding tree. All you have to do is to specify the required data source for the ASPxTreeList control.

Run Demo

Bind to a Standard Data Source

When binding to a standard data source, you need to have two service fields to build a tree. One should specify a record's unique ID and the other should specify the parent record's ID.

Dynamic Node Loading - Virtual Mode

Per your choosing, you can populate only root-level nodes within the tree. Attempts to expand parent nodes with children will raise an event wherein you can specify the child nodes to be displayed. This approach offers significant performance gains against large datasets.
