What problem does it solve? Building cross-tabular pivot reports in WPF requires correctly wiring the DevExpress PivotGridControl's DataSource, field areas, aggregation functions, and grouping intervals, which differs significantly from the standard GridControl and trips up developers on namespaces, binding modes, and engine selection. ## Core Features & Use Cases - Pivot Grid Setup & Binding: Add PivotGridControl to .NET 6/7/8+ or .NET Framework 4.6.2+ WPF projects and bind to DataTable, List<T>, Entity Framework, OLAP cubes, server-mode, or asynchronous sources. - Data Shaping & Aggregation: Configure PivotGridField objects in Row/Column/Data/Filter areas with Sum/Count/Average/Custom aggregation, date and numeric grouping intervals, sorting, filtering, and window calculations. - Advanced Visualization: Apply conditional formatting, OLAP KPIs, ChartControl integration, MVVM field generation, layout persistence, and print/export to PDF, XLSX, HTML, CSV, and more. - Use Case: A developer needs a sales dashboard showing total sales per Country by Year with drill-down and Excel export; the skill provides the XAML namespace, field setup code, grouping intervals, and export calls to build it. ## Quick Start Ask the AI to create a WPF pivot grid bound to a DataTable with Country in rows, Year in columns, and summed Sales in data cells using the DevExpress PivotGridControl.
