What problem does it solve? Implementing a full-featured data grid in WPF requires deep knowledge of the DevExpress GridControl API surface—data binding modes, views, editors, validation, and export—and mistakes often only surface at build or runtime. This Skill provides verified guidance, decision matrices, and working code patterns so you configure the grid correctly the first time. ## Core Features & Use Cases - Data Binding & Large Datasets: Bind GridControl to local collections, Entity Framework Core, XPO, server-mode sources, or virtual sources for millions of rows. - Full Feature Configuration: Set up columns, bands, sorting, filtering, grouping, summaries, master-detail, conditional formatting, validation, drag-and-drop, and printing/exporting (XLSX/CSV/PDF). - Use Case: You need a WPF order-management screen where users edit rows with ComboBox editors, validate input via MVVM commands, group by customer, and export the result to Excel—this Skill walks you through each step with verified XAML and C#. ## Quick Start Ask the assistant to add a DevExpress GridControl bound to an ObservableCollection of orders in a net8.0-windows WPF project with sorting, grouping, and a total summary.
