A 100% Native VCL control library, the ExpressQuantumTreeList represents the most advanced tree-list technology available for VCL developers. The ExpressQuantumTreeList Suite is a power-packed component library that will help you create killer applications, deliver unbelievable features to your end-users, and blow away your competition - all without writing a single line of source code!

Multiple Display Options:

The ExpressQuantumTreeList supports multi-column display of hierarchical data, stacked and multi-line columns, nested and fixed bands - all available with data shaping and layout customization capabilities such as Sorting, Data Editing using Embedded Cell Editors, Column/Band Reordering, Resizing and Visibility Control, Column Auto Width, Extendable Context Menus, Adjustable Node Height and Customizable Expand Button Position.

Ultra-Fast Information Display:

The ExpressQuantumTreeList Suite provides three Tree List components tailored for use in supported data loading modes - bound, unbound, or provider mode. In bound mode, the ExpressQuantumTreeList can present any self-referenced data structure. In provider mode, you implement a custom data source or handle specially designed events to dynamically supply data. Unbound mode allows you to manually populate the tree as required.

Regardless of the data loading mode you choose to use with the ExpressQuantumTreeList, it has been engineered to organize the information and render it on screen in the most efficient way possible. Data-aware modes support on demand loading of individual nodes and optimized node updates, resulting in ultra-fast information display.

Data Sorting and Incremental Search:
Data Sorting and Incremental Search

Unlimited data sorting allows you and your end-users to use as many columns as required in the tree. Take full control over data sorting by implementing your own value comparer.

Built-in incremental search delivers an easy and straightforward way for end-users to locate information within the tree. To execute a search, simply enter text within a cell and the Tree List will focus the first node that have the matching column value.

Summary Computations:
Summary Computations

Five predefined aggregate functions (COUNT, MAX, MIN, SUM and AVERAGE), adjustable calculation base and the ability to provide custom logic for calculating summary values via event handlers gives you unlimited computation options.

End-users can calculate any of these summaries at runtime by using the appropriate Footer context menu item.

Unmatched Data Editing and Validation Options:
Unmatched Data Editing and Validation Options

The ExpressQuantumTreeList ships with the ExpressEditors Library - a collection of over 90 standalone field editors and individual controls - many available in data-aware and non data-aware editions. 30 of them can be embedded into data cells for editing and better data presentation.

Advanced data editing options include: input validation and error indication, integrated UI for adding, deleting and navigating nodes.

Node Selection and Drag-and-Drop Options:
Node Selection and Drag-and-Drop Options

With a comprehensive node selection support, your end-users can select individual or multiple nodes. Built-in support for node groups allows you to display radio buttons or check boxes inside nodes simplifying selection.

By enabling drag and drop you allow your end-users to rearrange and clone nodes, and exchange data between the Tree List and external controls that support drag and drop.

Data Export and Printing:
Data Export and Printing

Numerous data exchange options include WYSIWYG data printing along with data export to many popular document formats (PDF, HTML, XML, TXT, XLS, XLSX, and XML).

By using the DevExpress ExpressPrinting System, you can render the Tree List with ease (including all customization settings such as appearance aspects of individual elements, column/band visibility, node expansion, etc.)
