Implementing .NET MAUI DataGrid

A comprehensive skill for implementing and customizing the Syncfusion .NET MAUI DataGrid (SfDataGrid) control. The DataGrid displays and manipulates data in a tabular format with support for columns, editing, sorting, filtering, grouping, summaries, paging, and export features.

When to Use This Skill

Use this skill when you need to:

• Display tabular data in a .NET MAUI application
• Bind data sources (IEnumerable, ObservableCollection, DataTable) to a grid
• Configure columns (auto-generated or manual)
• Implement cell editing and validation
• Add sorting, filtering, or searching functionality
• Group data and display summaries/aggregates
• Implement paging or incremental loading
• Enable row operations (drag-drop, swipe, add/delete)
• Export grid data to Excel or PDF
• Customize grid appearance and behavior
• Optimize performance for large datasets
• Implement master-detail views or custom row templates

Component Overview

SfDataGrid is a high-performance data grid control for .NET MAUI that provides:

Core Features:

• Multiple data binding options (IEnumerable, DataTable, dynamic objects)
• Auto-generated or manually defined columns
• 8+ column types (Text, Numeric, Date, Checkbox, Image, ComboBox, Picker, Template)
• In-cell editing with validation
• Multi-column sorting and filtering
• Interactive grouping with summaries
• Selection modes (Single, Multiple, None)
• Paging and data virtualization
• Excel and PDF export
• Advanced views (Master-Details, Record Templates)
