Data Shaping & Presentation
When bound to data, the control 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 WinForms TreeList is a drop-in replacement for the standard Microsoft TreeView. Nodes within the WinForms TreeList represent hierarchical data structures. Unlike a treeview, however, the TreeList can also display columns for each Node.
Data Bands
Optimize screen real-estate for easier data consumption.
Data Bands
End-users can hide, display and reorder entire column sets instead of performing the same operation on each column individually.
Data Columns
Multi-column display of hierarchical data.
Data Columns
You can enable Column Auto Width, Column Reordering and Resizing, Fixed Columns, Field Chooser Window and Extendable Context Menus.
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 WinForms 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
This feature allows end-users to both sort data inside the control 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.

Data Filtering & Editing
In addition to a full suite of built-in UI tools to simplify data filtering, the TreeList includes 20 controls can be embedded into cells for data editing and better data presentation.
In-Cell Editing
Use any of our 20+ Data Editors.
In-Cell Editing
Over 20 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.
Data Validation
Reduce data entry errors and visually inform users of invalid input.
Data Validation
We know that no single solution can address all Data Validation requirements and as such, the our controls ship with two options to validate data for accuracy. You can manage Data Validation at both the TreeList and Data Level. If you've specified Validation rules, the control will communicate the validity of data entered into individual cells.
Instant Search Panel
The easiest way to find data.
Instant Search Panel
Much like Microsoft Outlook's mailbox search feature, the Search Panel provides an easy and straightforward way to locate data. To execute a search, simply press CTRL+F, enter text within the Find box and the grid will display those records that have matching values. Multiple options give you control over the display and behavior of the Search Panel. You can specify search columns, choose between automatic or manual search modes and allow search results to be highlighted.
Auto-Filter Row
Straightforward column based search.
Auto-Filter Row
Inspired by Microsoft Excel, the AutoFilter Row is an alternative to our Column-Based Filtering option. Once enabled, it displayes an additional row below column headers. Cells within the AutoFilter Row are used to specify a filter operator (equals, less than, greater than, etc) and the search criteria.
Column Header Filter
Unobtrusive column based filtering.
Column Header Filter
The fully integrated Column-Based Filtering option gives you and your users an intuitive alternative to more traditional filtering mechanisms. Options include the ability to display most recently used (MRU) filters, incremental search, and Template support so you can roll your own column filter UX (For instance, you can use a TrackBar to restrict the range of filter values).
Query Builder & more
A simple to use UI for creating advanced filter expressions.
Query Builder & more
The built-in Custom Filter Editor gives you and your users more granular control over filter construction. The Filter Editor displays filter criteria as a tree structure, where nodes represent simple filter conditions. If the filter criteria consist of multiple filter conditions, the Filter Editor contains multiple nodes linked by logical operators into groups.

UI Customization & Tree List Behaviors
A variety of customizable UI elements and behaviors give you meticulous control over the TreeList's runtime capabilities.
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. 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
Our WinForms TreeList allows end-users to customize columns and band layout at runtime. The control'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 & Cell Selection
Select multiple nodes/rows with the keyboard or mouse.
Node & Cell 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
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.
Appearance Customization
Deliver elegant line-of-business applications.
Appearance Customization
You can create complex styles and apply them conditionally to reflect certain element states (for instance, even and odd styles for nodes). Moreover, by using conditional formatting, you can customize the appearance of any node element based on complex logical conditions.

Printing, Export & More
Multiple data rendering and reporting options via a built-in WYSIWYG printing engine. Includes data export to multiple file formats including XLS, PDF, HTML, etc.
Data-Aware Export to Excel
Optimized Excel data exchange options.
Data-Aware Export to Excel
We've made it easy to exchange data between your WinForms app and Microsoft Excel. Exported TreeList data retains all data grouping hierarchies, conditional formatting, as well as total and group summaries. The output file can thus be opened in Excel and further manipulated (sorted, filtered, analyzed) as necessary.
Ad-hoc Reporting
WYSIWYG printing engine is built-in.
Ad-hoc Reporting
Create custom (ad-hoc) reports based on data displayed in your control. End-users can either generate a report using the default layout or they can customize the report using Report Customization options.
Clipboard Operations
Copy and paste fully fomatted content.
Clipboard Operations
End-users can copy data to the clipboard in XLS (Biff8), RTF, HTML, CSV and plain text (ANSI and Unicode) formats. Once you copy data to the clipboard, the TreeList will retain all formatting including appearance settings applied to the control and its individual columns, appearance settings customized via dedicated events and any Excel-style cell conditional formatting.
