Demo

Data Binding Options

Populate the TreeList by binding it to any standard data source or to any object that represents a tree structure. Use virtual mode to significantly improve performance when displaying large tree hierarchies.

Demo

Data ShapingData EditingUI Customization

Data Shaping & Presentation

When bound to data, the DevExpress ASP.NET 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

Use it as a drop-in replacement for the standard treeview.

Tree Nodes

Our ASP.NET TreeList is a drop-in replacement for the standard Microsoft ASP.NET TreeView. Nodes within the ASP.NET TreeList represent hierarchical data structures. Unlike a treeview, however, the TreeList can also display columns for each Node.
DemoDocumentationExamples

Columns

Use it as a hybrid UI element - a tree and listview in one.

Columns

Data columns represent individual data source fields. They include a clickable Column Header and associated Data Cell. An optional Command columns allows end-users to activate data edit mode, update data, add and delete nodes, etc.
DemoDocumentation

Sorting

Sort against an unlimited number of TreeList columns.

Sorting

You can sort data against an unlimited number of columns. When necessary, you can disable runtime sort options and handle all sort operations in code. Sort order is automatically indicated within the appropriate column using a glyph.
DemoDocumentation

Summaries & Aggregates

Compute summaries with 5 pre-defined aggregate functions.

Summaries & Aggregates

The DevExpress ASP.NET TreeList allows you to compute Summaries for all cell values within a column or across a group of tree nodes. These Summaries (you can compute summaries for any number of columns) can be displayed within the TreeList's Footer or Group Footer cells. Five predefined aggregate functions (COUNT, MAX, MIN, SUM and AVERAGE) are available.
DemoDocumentation

Conditional Formatting

Apply custom styles to differentiate key data points.

Conditional Formatting

Conditional Formatting
Our Tree List control provides custom style settings so you can paint individual data cells or entire nodes. In this animation, the TreeList's HtmlRowPrepared event is used to color rows green (if Location = Monterey) and the HtmlDataCellPrepared event handler is used to color Budget cells yellow (color brightness is based on a cell's value and those over one million use a bold font effect).
DemoDocumentation

Alternating Node Style

Use alternating row styles to improve readability.

Alternating Node Style

Alternating Node Style
To improve readability, you can apply a Style against alternating (even) nodes within the ASP.NET TreeList. In this animation, we've set the Styles.AlternatingNode.Enabled property to true. To override the default style and provide your own Style settings, use the Styles.AlternatingNode property.
DemoDocumentation
"The DevExpress ASP.NET Suite is the perfect set of controls to help DataClara create the professional, high perfomance, and flexible solutions that our clients need."Eric McGrail

Data Editing

The TreeList control includes multiple data editing options - be it inline within the control or via customizable popups.

Inline Cell Editing

Edit data directly within TreeList cells.

Inline Cell Editing

Use our Inline Cell Editing mode to modify cell values directly within TreeList's cells.
DemoDocumentation

Inline Edit Forms

Use a custom inline edit form to modify node/column values.

Inline Edit Forms

If you do not want to enable data editing within TreeList cells, you can activate the control's Inline Edit form instead. By using Templates, you can create a customized layout for the Inline Edit Form as needs dictate. In this animation, we've used our ASP.NET Page Control to help reduce space occupied by the Edit Form.
DemoDocumentation

Popup Edit Forms

Use a custom popup edit form to modify node/column values.

Popup Edit Forms

Cell values can be edited within the Popup Edit Form. By default, the Popup Edit Form is displayed near the edited tree node. The Popup Edit Form can be dragged and its default position can be customized via the SettingsPopupEditForm property.
DemoDocumentation

Data Editors

Edit TreeList values with one of over a dozen data editors.

Data Editors

Data editors that ship inside our ASP.NET Data Editors Library are fully supported. Features include advanced masked input, display value formatting, a built-in data validation engine and rich client-side functionality.
DemoDocumentation

Templates

Customize the appearance and behavior of the TreeList.

Templates

Templates
Built-in templates allow you to create custom layouts for column headers, data and footer cells, etc.
DemoDocumentationExamples

Data Validation & Error Indication

Reduce data entry errors and visually inform users of invalid input.

Data Validation & Error Indication

You can manually Validate edited nodes and display errors for invalid field values. In this animation, Validation is implemented within the NodeValidating event handler. Invalid values are indicated via error icons. Hovering the mouse over an icon displays a hint along with an error description.
DemoDocumentation
"Working with devexpress for more than 3 years now, and still I discover new excellent possibilities on a daily basis! Way to go guys, your developer suite rocks!"Andy Luyten

UI Customization & TreeList Behaviors

A variety of customizable UI elements and behaviors give you meticulous control over the TreeList's runtime capabilities.

Column Customization

Put control over column display in the hand of your end-users.

Column Customization

Much like Microsoft Outlook's Column Chooser, the TreeList's Customization Window displays all hidden column headers (those that you specify at design time or those an end-user has selected to remove from a webpage). Use it to hide columns or to make columns visible at runtime via intuitive drag & drop operations. The TreeList's SettingsCustomizationWindow property allows you to specify the Customization Window's availability, caption, position, etc.
DemoDocumentation

Node Preview

Use memo fields to display extended tree node information.

Node Preview

Node Preview
Node Preview allows each tree node to display a preview pane. Preview panes are fantastic ways to display large memo fields or custom data across all TreeList columns. To enable the Preview, simply set the Settings.ShowPreview property to true.
DemoDocumentation

Column Resizing & Tree Lines

Improve readability and resize column width on the fly.

Column Resizing & Tree Lines

End-users can resize TreeList column width by dragging the appropriate column header border.  Options include the ability to change the width of the control when header width is modified or to reduce the width of the column immediately to the right. The TreeList also provides multiple options to control the visibility of its tree and grid lines as well as the control's border.
DemoDocumentation

Data Paging

Navigate tree nodes with an intuitive data pager.

Data Paging

As you might expect, TreeList content can be split across multiple pages whenever the control's built-in Data Pager is enabled. You can control the position of the pager, along with the visibility of the page size combobox and associated navigation buttons.
DemoDocumentationExamples

Scrolling

Allow users to scroll both vertically and horizontally.

Scrolling

For utmost UI flexibility and when you do not want to use a pager to navigate the contents of the TreeList, you can enable both a vertical and horizontal scrollbar.
Demo

Node Selection

Enable multiple node selection via checkboxes.

Node Selection

Use the TreeList's Focused Node feature to highlight records within the control. Enable node selection by using check boxes and optionally enable recursive selection to allow end-users to modify the selected state of child nodes using a single click on a parent node.
DemoDocumentationExamples

Themes

Control the appearance of the TreeList via built-in app themes.

Themes

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.
Demo

Drag & Drop

Enable intuitive drag & drop operations within and outside the TreeList.

Drag & Drop

You can allow end-users to move tree nodes via drag and drop either within the TreeList itself or between the TreeList and external controls.

The ASP.NET Subscription helps you leverage your current investments and address customer needs via a comprehensive range of Web Forms Controls and MVC Extensions that support touch on iOS Safari, Android and Internet Explorer 10.

AJAX Enabled with Rich Client-Side API

Each and every control provides an ability to update the control using callbacks, eliminating the need to re-load the entire page. This callback functionality allows you to optimize how data is transferred to the client. We also offer you a comprehensive client-side API, along with the ability to handle events on the client side. With our ASP.NET components, you have full control over the control's behavior via client functions.

Fast and Lightweight with XHTML Compliance

DevExpress controls are optimized for exceptional performance and efficient memory use without the loss of functionality or features. DevExpress ASP.NET controls also support optimizations like HTML compression, callbacks, image sprites, resource caching and sharing. Key ASP.NET controls in this subscription use semantic HTML to keep output clean and minimal. The semantic HTML markup means that web pages are lighter and faster, more search engine friendly and provide improved accessibility for screen readers.

Straightforward Localization

All DevExpress ASP.NET AJAX Controls can be easily localized using satellite resource assemblies. DevExpress delivers satellite assemblies for a large variety of languages and cultures. To make it easy to get started, resource files for three cultures are included to our installation: German, Japanese, and Spanish. If you need to modify our shipping resources or create satellite assemblies for a different language, simply use our Online Localization Service, a free tool for our active ASP.NET subscribers.
