ASPxTreeList can be easily populated with data by binding to any standard data source. You can also bind the ASPxTreeList to any object that represents a tree structure, or manually create a tree in code. In addition, the ASPxTreeList can operate in Virtual Mode and greatly improves performance when displaying large tree hierarchies. In this mode, child nodes are created and initialized on demand, only when their parent node is expanded for the first time.

Provide your end-users with the capability to easily select all or individual nodes, using check boxes. You can optionally enable recursive selection to allow end-users to change the selected state of child nodes using a single click on their parent node. In addition to selection, you can use node focus to highlight one node at a time.

Switching a single option allows end-users to edit tree data in-line or within a form. The form's content, layout, and position (within the control or in a popup window) can be easily customized, as your needs dictate.

ASPxTreeList allows you to calculate and display any number of summaries (total and group), for the entire tree and individual nodes. You can opt to calculate summaries using built-in aggregate functions or implement custom aggregate functions.

Data Sorting

Automatic column sorting for any data source allows you to sort against an unlimited number of columns, without writing a single line of code. A column's current sort order is indicated by a sort glyph displayed at the column header's right edge. If the column isn't sorted, the sort glyph is hidden.

Customization Window

If end-users need to temporarily hide columns or make hidden columns visible, you can enable a Microsoft Outlook style Field Chooser window. End-users can simply drag fields to the window to hide them and then drag them back to the column header panel to make them visible again.

Built-in Pager

ASPxTreeList can automatically split content across multiple pages, and provide the built-in pager that enables end-users to navigate through the data.

Exporting Data

ASPxTreeList allows you to easily export data via the ASPxTreeListExporter component. Data can be exported to a file or stream in the following formats:

• PDF
• RTF
• XLS, XLSX

In addition to a number of built-in themes, you can use style properties and CSS for appearance customization. Templates that are available for most control elements, enable you to easily adjust and enhance a control layout.
