devexpress-winforms-data-grid

devexpress-winforms-data-grid is a skill for Claude Code from DevExpress/agent-skills. It costs 213 tokens per session (6,577 once invoked), scanned A, original, MIT.

A guide to DevExpress WinForms controls for displaying data in tables, cards, tiles, or hierarchical trees. The data grid presents rows and columns, while the tree list shows parent-and-child relationships.

In plain words
What is it for?
Use it to build data tables, card or tile views, master-detail screens, and hierarchical lists, including data loaded in the background or in large amounts.
Why use it?
It helps connect data to the right visual layout and configure common behaviors in one place. These include sorting, filtering, editing, validation, selection, and saving the layout.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

devexpress-winforms-data-grid scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 9d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

DevExpress WinForms Data Grid, Tree List, and CardView

DevExpress WinForms Data Grid (DevExpress.XtraGrid.GridControl) is a high-performance, DirectX-accelerated data-aware container that uses a flexible View-based architecture. A single GridControl hosts one or more views — GridView (tabular), BandedGridView, AdvBandedGridView, CardView, LayoutView, TileView, WinExplorerView — each presenting the same underlying data differently. The TreeList control (DevExpress.XtraTreeList.TreeList) is a separate but conceptually similar control for hierarchical data with parent-child relationships.

Many concepts are shared across GridView, BandedGridView, CardView, LayoutView, and TreeList: data binding, column/field definition, in-place editors, conditional formatting, validation, filtering, sorting, focus/selection, drag-and-drop, and layout persistence. Some concepts are unique: master-detail belongs to GridControl, hierarchical node manipulation belongs to TreeList, and card-specific layout settings belong to CardView/LayoutView. This skill covers all three controls in one place because developers rarely use them in isolation.

When to Use This Skill

  • Bind a grid or tree list to any data source (DataTable, BindingSource, IList, Entity Framework, XPO, LINQ to SQL, MongoDB, JSON, ServerMode/InstantFeedback sources, VirtualServerModeSource for infinite scrolling).
  • Define columns in InitializeComponent(), via auto-generation (AutoPopulateColumns), or in code (PopulateColumns, Columns.AddVisible). Configure unbound columns with UnboundExpression or CustomUnboundColumnData.
  • Assign in-place editors with RepositoryItem descendants (RepositoryItemSpinEdit, RepositoryItemLookUpEdit, RepositoryItemCheckEdit, RepositoryItemProgressBar, RepositoryItemRichTextEdit, etc.). Use CustomRowCellEdit and CustomRowCellEditForEditing for per-cell editors.
  • Format cell values (DisplayFormat, EditFormat, CustomColumnDisplayText) and switch between in-place edit, edit-form, and edit-entire-row modes.
  • Apply conditional formatting (color scales, data bars, icon sets, expressions) via FormatRules.
  • Validate cell or row input with ValidatingEditor, ValidateRow, InvalidValueException, SetColumnError, or IDXDataErrorInfo.
  • Configure UI filtering (Excel-style filters, Auto Filter Row, Filter Editor, Find Panel) and apply filters in code (ActiveFilterString, ActiveFilterCriteria, CustomRowFilter, SubstituteFilter).
  • Implement sorting and grouping, including custom comparisons (CustomColumnSort, CustomColumnGroup), grouping by display text, and grouping by date intervals.
  • Build master-detail layouts with multiple nesting levels, hide detail relations conditionally, and access clone views.
  • Print and export data (data-aware export to XLS/XLSX/CSV, WYSIWYG export to PDF/HTML/RTF, customize exported cells via XlsxExportOptionsEx.CustomizeCell).
  • Configure focus and selection (FocusedRowChanged, MultiSelect, MultiSelectMode, Selection Binding).
  • Implement drag-and-drop between Grid, TreeList, and ListBox via the Drag-and-Drop Behavior.
  • Work with TreeList nodes programmatically (AppendNode, FocusedNode, FindNodeByKeyID, virtual mode).
  • Configure CardView layout (card size, caption, row/column counts).
  • Save and restore layout to XML, JSON, Stream, or system Registry.

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
