Flexibility is the keyword behind all Developer Express .NET components. The XtraTreeList lives up to this commitment by giving you a variety of ways in which to display information to your end users using a Tree/Grid display metaphor. Unlike competing products that box you into a corner, the XtraTreeList gives you the wherewithall to deliver INTUITIVE applications and RADICALLY reduce the amount of source code you have to write.

• Represent Hierarchical Data Relationships - With the XtraTreeList, you can represent any self-referenced data structure without hassles... In bound or un-bound mode.


• 　


• Full ADO.NET Support - The XtraTreeList takes full advantage of ADO.NET. By using this new data access architecture and by separating internal data modules from data presentation, the XtraTreeList does not use any extra buffers, thus greatly improving performance and reducing memory use. The importance of this feature cannot be overstated...compare the memory footprint of the XtraTreeList to other similar controls and you will see its advantages like night and day.


• 　


• Advanced Unbound Mode Support - The XtraTreeList works with any source which supports an IList or ITypedList interface, along with all inherited interfaces.


• 　


• Advanced Design-Time Support - You can use the XtraTreeList component editor for fast and easy design time setup.


• 　


• Built in XP Theme Support - The XtraTreeList fully supports XP Themes.


• 　


• Flexible Display Formats - Whether you wish to display information to users in the form of a tree or a grid, the XtraTreeList gives you all the tools necessary to carry out the task.


• 　


• Automatic Sorting Against an Unlimited Number of TreeList Columns - With the XtraTreeList, you can sort against an unlimited number of columns, all without writing a single line of code!


• 　


• Runtime Column Customization - Yes, you would never think that a tree control would have this capability, but because the XtraTreeList is a hybrid Tree/List, your end-users can customize the columns on-screen using intuitive drag and drop operations...And best of all, you dont have to write any code to enable this capability!


• 　


• Automatic Runtime Column Resizing - With the XtraTreeList, your users can easily adjust the height of nodes (rows) to meet their specific needs.


• 　


• Automatic Runtime Column Drag & Drop Support - With the XtraTreeList, your end-users can control the appearance of the TreeList as they wish by adding and removing columns using simple drag and drop.


• 　


• Standard and Extended Multi-Select Operations - Unlike competing Tree products, the XtraTreeList gives you both standard node select and multi-node select capabilities.


• 　


• XtraEditors Library Integration - No more hassles or limits when it comes to using editors within a treeview. XtraTreeList works in concert with our XtraEditors Library allowing you to use all our field editors (from date controls to combo boxes) directly within your TreeList.


• 　


• Editor Repository - You can setup a single in-place editor, for instance a pick image edit as an editor for a payment type field, and then reuse it for as many TreeLists fields as you wish. When you use the repository and you have to add a different credit card payment type, you need only change one in-place editor.


• 　


• Auto Preview Pane - Similar to the MS Outlook® Grid, allows you to display long text strings to users within the TreeList itself.


• 　


• Auto Width - Automatically fit all displayed columns within the TreeList control to eliminate the horizontal scroll bar.

• 　


• Data Summaries - The XtraTreeList is not just about the display of information...Via our integrated data summary support, you can perform aggregate functions against tree nodes or as a footer with simple property settings.


• 　


• Tree Line Styles - In concert with the custom draw capabilities of the XtraTreeList, you can customize the appearance of tree lines via our LineStyle property.


• 　


• ITreeListPaintHelper Interface - This advanced painting mechanism allows you to easily implement any drawing routine without the need to use CustomDraw.
