From the author
Build WPF applications with the DevExpress TreeList (TreeListControl) — a data-aware control for hierarchical data. Use when adding TreeListControl, binding to self-referential data (Key/Parent fields), hierarchical data (ChildNodesPath/Selector/DataTemplate), or building unbound trees with TreeListNode. Covers TreeListColumn, sorting, filtering, summaries, expand/collapse, drag-and-drop, multi-selection, edit forms, validation, conditional formatting, printing, exporting. Also use when someone mentions "DevExpress WPF tree", "TreeListControl", "TreeListView", "dxg:TreeListControl", "DevExpress.Xpf.Grid.TreeListControl", "self-referential tree", "KeyFieldName ParentFieldName", "unbound tree", or asks about org charts, file trees, project hierarchies, BOM, parent-child collections, or any tree UI in WPF. Covers both .NET 8+ and .NET Framework 4.6.2+.

- devexpress-winforms-tree-listDevExpress/agent-skillsExpert skill for the DevExpress WinForms TreeList control (DevExpress.XtraTreeList.TreeList, DevExpress.Win.TreeList NuGet) — a data-aware control that shows data as a tree, a multi-column tree-grid, or both. Use when binding self-referential data (KeyFieldName, ParentFieldName, RootValue), building unbound trees in code (AppendNode, BeginUnboundLoad/EndUnboundLoad), dynamic on-demand loading (TreeListNode.HasChildren + BeforeExpand), defining TreeListColumn and unbound columns (UnboundExpression), in-place editors (ColumnEdit, RepositoryItems), sorting, filtering (ActiveFilterString, Find Panel), summaries, conditional formatting (FormatRules), node operations (FocusedNode, FindNodeByKeyID/FieldValue, Expand/Collapse, checkboxes, images), drag-and-drop, printing, and export. Use when a user asks about WinForms tree, TreeList, XtraTreeList, hierarchical grid, tree-grid, org charts, file/folder trees, parent-child data, TreeListNode, or multi-column tree view. For flat tabular data use the Data Grid instead.Writing★ 66
- devexpress-wpf-data-gridDevExpress/agent-skillsBuild WPF applications with the DevExpress Data Grid (GridControl) — a data-aware control that displays and edits data in table, card, and treelist layouts. Use when adding GridControl to a WPF project, configuring columns and editors, sorting, filtering, grouping, summaries, master-detail, conditional formatting, printing, and exporting (XLSX/CSV/PDF). Also use when someone mentions "DevExpress WPF grid", "GridControl", "TableView", "CardView", "TreeListView", "dxg:GridControl", "DevExpress.Xpf.Grid", "DevExpress.Wpf.Grid", "Items Source Wizard", "WPF data grid", or asks about grid CRUD operations, or already knows which data-binding API to use (Entity Framework Core, XPO, ICollectionView, or a specific server-mode/instant-feedback class they've already picked). For deciding *which* data source to use in the first place — including large datasets or real-time/streaming grids — see the `devexpress-wpf-grid-datasource` skill. Covers both .NET 8+ and .NET Framework 4.6.2+.Data★ 66
- devexpress-blazor-treelistDevExpress/agent-skillsBuild and configure the DevExpress Blazor TreeList (DxTreeList) — a hierarchical data grid / tree grid for Blazor Server, WebAssembly, and Hybrid apps. Use when displaying tree-structured or parent-child data; binding flat data with KeyFieldName, ParentKeyFieldName, and RootValue; expanding/collapsing nodes; sorting, filtering, search box, and filter panel; implementing CRUD editing for tree nodes; exporting to CSV/XLSX/PDF; loading child nodes on demand; and reordering/re-parenting nodes with drag-and-drop. Also use for DxTreeList, DevExpress TreeList, tree grid, hierarchical grid, parent-child table, and tree grid feature comparisons or migration scenarios.Data★ 66
- devexpress-wpf-grid-datasourceDevExpress/agent-skillsSelects and implements the right DevExpress WPF GridControl or TreeListControl data source — ObservableCollection<T>, Server Mode, Instant Feedback, Virtual Sources, or RealTimeSource — by inspecting the project first. Use when binding GridControl or TreeListControl to data, a database, or REST API, or building a real-time/large-dataset grid. Covers .NET 8+ and 4.6.2+.Data★ 66
- devexpress-wpf-pivot-gridDevExpress/agent-skillsBuild WPF applications with the DevExpress Pivot Grid (PivotGridControl) — a control for multi-dimensional data analysis displaying data in a cross-tabular pivot table. Use when adding PivotGridControl to a WPF project, binding to DataSet/DataTable, Entity Framework, OLAP cubes, server-mode sources, or in-memory data; creating PivotGridField objects and positioning them in Row/Column/Data/Filter areas; configuring aggregation, grouping intervals, filtering, sorting, drill-down, KPI, conditional formatting, chart integration, printing, and exporting. Also use when someone mentions "DevExpress WPF pivot", "PivotGridControl", "dxpg:PivotGridControl", "DevExpress.Xpf.PivotGrid", "OLAP", "cube", "FieldArea RowArea ColumnArea DataArea", "PivotGridField", "DataSourceColumnBinding", or asks about cross-tab reports, drill-down analytics, multi-dimensional data, or pivot tables in WPF. Covers both .NET 8+ and .NET Framework 4.6.2+.Data★ 66
- devexpress-wpf-property-gridDevExpress/agent-skillsBuild WPF property editors with the DevExpress PropertyGridControl — bind any object via SelectedObject (or multiple via SelectedObjects), define which properties show via PropertyDefinition, edit collections inline via CollectionDefinition (with NewItemInitializer for add/remove), group properties via [Category] attribute and CategoryDefinition (flat / Visible / Tabbed modes), and control expandability of nested objects via TypeConverter / ExpandableObjectConverter / AllowExpanding. Use when building visual designers, settings dialogs, diagram property panels, report designers, or any view that lets a user inspect and edit an arbitrary object's properties at runtime. Also use when someone mentions "PropertyGridControl", "PropertyDefinition", "CollectionDefinition", "CategoryDefinition", "ShowCategories", "ShowProperties", "ExpandableObjectConverter", "AllowExpanding", or "dxprg:". Covers .NET 8+ and .NET Framework 4.6.2+.Writing★ 66
