Expert 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.

From the source SKILL.md

TreeList is a data-aware control that displays data as a tree, a multi-column tree-grid, or a combination of both. It supports bound mode (any traditional data source plus KeyFieldName/ParentFieldName), unbound mode (nodes created in code via AppendNode), and virtual mode (load children on demand). Because it includes grid functionality, you also get sorting, filtering, searching, summaries, in-place editing, validation, conditional formatting, and export — applied to a hierarchy.

What this skill does

Devexpress Winforms Tree List is a community-contributed Claude Code skill in the backend sub-category. It ships as a SKILL.md file that Claude Code auto-discovers under ~/.claude/skills/devexpress-winforms-tree-list/ and loads when your prompt matches the skill's trigger.

When to invoke it: 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.
