The simplest end-user filtering tasks can be accomplished using Filter Dropdown Lists. The Tree List suite includes numerous filter features that allow users to create complex filter criteria based on their requirements. Learn how to implement custom sort algorithms for individual columns.ĭata filtering is an essential requirement for most software applications. The topic enumerates methods and properties that allow you to sort Tree List data programmatically. This topic illustrates how users can sort data at runtime. This topic contains technical information related to the sort functionality. The topics in this section explain how to sort Tree List data against specific columns. This topic also explains how to display and close cell editors in code. Learn how to specify the way a Tree List acts when users activate and/or close in-place editors. This topic shows how to assign different editors to different cells in the same column. This topic illustrates how to implement a typical scenario in which cells that belong to the same column use the same in-place editors. This topic explains how to get and set cell values. Learn how to embed DevExpress editors into your Tree List data cells. The topics in this section demonstrate different data editing techniques supported by the Tree List control. You can use expressions or a dedicated event to supply data for these columns. These columns are not bound to fields in the data source. Unbound columns allow you to display custom data within the Tree List control. This topic describes the Tree List’s Unbound Mode. This topic discusses a specific virtual mode case in which the Tree List is bound to an instance of a custom class. Virtual Mode - Binding to a Hierarchical Business Object (Data Source Level) Virtual Mode (Dynamic Data Loading) Using Events (Tree List Level)Įxplains how to load data into a Tree List dynamically using only events (virtual mode). Learn how the Tree List generates its node hierarchy and what requirements the control imposes on data sources. Tree Generation Algorithm in the Tree List This section contains general information on data binding concepts shared among all DevExpess data-aware controls. The section also explains unbound mode, in which you create nodes manually. This section contains information related to binding the Tree List control to various data types. The TreeView style is supported in single-column and multi-column modes. You can activate this visual style to imitate the appearance of the standard TreeView control. These regions are non-editable and designed to display large memo fields or custom data for a given record. Preview sections are regions below Tree List records stretched across the entire node width. This document describes band features, how to anchor bands, and how to organize them into a hierarchical structure. You can hide, display, and reorder bands along with their child columns. This topic contains detailed information on column objects, and their layout, behavior, and appearance settings.īands are visual and logical groups into which you can arrange columns. This section describes columns as well as elements related to the column layout - bands and preview sections. Nodes correspond to individual records, while columns match data source fields. The Tree List control uses nodes and columns to display data. This topic shows how to create custom nodes and use them in your Tree List control. The Nodes Iterator is an object that allows you to traverse Tree List nodes without writing recursive code manually. The documents in this section describe the term “node”, and include information on how to perform operations on nodes.Īn overview topic that explains Tree List nodes. Nodes, however, can be much more complex than a number of cells displaying dataset field values. The Tree List control uses nodes to display records of the associated data source. Enumerates all Tree List capabilities in a compact list format.ĭemonstrates all UI elements of the Tree List control.
