Data Shaping & Presentation
When bound to data, the DevExpress VCL TreeList can present any self-referenced data structure. In Unbound mode, it allows you to manually create and populate the tree as business needs dictate.
Tree Nodes
Display information as a tree.
Tree Nodes
Our VCL TreeList is a drop-in replacement for the standard Microsoft TreeView. Nodes within the VCL TreeList represent hierarchical data structures. Unlike a treeview, however, the TreeList can also display columns for each Node.
Data Bands & Columns
Optimize screen real-estate for easier data consumption.
Data Bands & Columns
Our VCL TreeList Control supports multi-column display of hierarchical data, data shaping and layout customization features such as Sorting and Filtering, Data Editing via Embedded Cell Editors, Advanced Scrolling Options, Column Auto Width, Column Reordering and Resizing, Fixed Columns, Field Chooser Window and Extendable Context Menus.
The TreeList Control ships with extended layout and customization options for complex datasets. End-users can hide, display and reorder entire column sets instead of performing the same operation on each column individually.
Multi-Column Sorting
Sort data against an unlimited number of columns.
Multi-Column Sorting
Sort against an unlimited number of TreeList columns using the same UX as that found in our VCL Data Grid.
Summaries & Aggregates
Automatically compute summaries across all TreeList elements.
Summaries & Aggregates
Five predefined aggregate functions (COUNT, MAX, MIN, SUM and AVERAGE) and the ability to provide custom logic for calculating summary values via event handlers gives you a limitless set of computation options. End-users can calculate any of these summaries at runtime by using the appropriate Footer context menu item.
Conditional Formatting
Highlight node and cell values for maximum data clarity.
Conditional Formatting
The VCL TreeList Control supports Excel-inspired Conditional Formatting of individual data cells. This feature allows end-users to both sort data inside the TreeList AND to visualize selected cells with data bars, icons and predefined or custom appearance schemes. The following comparison rules are fully supported: Top/Bottom, Above/Below Average, Greater/Less Than, Value List, Unique/Duplicate.
"Of all of the tools that I purchase and maintain, the DevExpress tools are the most valuable. The price is reasonable, the tools are fabulous and your support, in the rare case that it is needed, is stellar."

In-Cell Editing
Over 30 controls that can be embedded into data cells for editing and better data presentation. Our editors provide seamless integration with the rest of our product line, including the Data Grid and Ribbon controls.
Advanced data editing options include: Input Validation and Error Indication, integrated UI for adding, deleting and navigating nodes.
Fixed Bands & Columns
Anchor bands and columns for improved readability.
Fixed Bands & Columns
Fixed Bands and Columns allow you to anchor bands/columns to the left or rightmost edge of the TreeList. These fixed bands/columns are never scrolled horizontally and as such, allow you to create solutions that offer improved readability and visual clarity. Typical use-cases involve financial and data entry intensive applications.
Column Customization
Runtime node/column customization made easy.
Column Customization
The DevExpress VCL TreeList allows end-users to customize columns and band layout at runtime. The TreeList's Column Chooser can add/remove both columns and bands with simple drag & drop operations. When used in conjunction with the Printing engine, column customization provides an ad-hoc reporting option for end-users.
Node Selection
Select multiple nodes/rows with the keyboard or mouse.
Node Selection
The VCL TreeList Control fully supports node/record selection. You can restrict record selection to individual nodes/records or you can allow end-users to select multiple nodes.
Node Drag & Drop
Rearrange node hierarchies and move data objects outside the TreeList.
Node Drag & Drop
With a comprehensive node selection support, your end-users can select individual or multiple nodes using the mouse or keyboard. Integrated Node Drag & Drop support means that your end-users can rearrange node hierarchies and move data objects outside the TreeList to external controls that support drag and drop.
