The Most Trusted C# .NET DataGrid Control
C# .NET datagrids are feature-rich UI components for displaying tabular data. They provide data binding, editing, grouping, sorting, filtering, selecting, and exporting data to a variety of formats similar to Microsoft Excel. FlexGrid is a powerful cross-platform datagrid control built to support the entire .NET stack.
.NET Datagrid Highlights
The Go-To Cross-Platform .NET DataGrid
FlexGrid is the only datagrid control that spans the entire .NET stack (and JavaScript!). FlexGrid has been trusted by .NET developers for more than 30 years and spans every .NET framework, including WinForms, WPF, WinUI, Blazor, ASP.NET Core, and .NET MAUI. Its flexible API helps developers achieve closer to 100% of their requirements compared to most other third-party datagrids.

High-Performance Data Grids for Massive Datasets
FlexGrid’s lightweight architecture has been designed with large data sets in mind. Its built-in UI virtualization makes it possible to load millions of rows and hundreds of columns. You can further improve performance and reduce load times for very large data sets with on-demand loading, where data is only retrieved as the user scrolls. This feature is also known as "Virtual Mode" and is supported in FlexGrid through the DataCollection component.

The Perfect DataGrid with All the Excel Features You Need
FlexGrid is a complete .NET datagrid with features inspired and designed to behave like Microsoft Excel. This ensures familiarity for end-users as they don’t need to learn a new way to edit, analyze and copy data. You can effortlessly enable many Excel-like features in FlexGrid, such as filtering, selection, cell merging, cell freezing, formatting, and clipboard operations.
See:
Dynamically Format and Customize Cells
One of the main strengths of FlexGrid is the ability to customize every aspect of the entire grid’s appearance and individual cells. Easily embed sparklines, images, ratings, or any UI component in the cells. Most datagrids let you customize entire columns with just one template, but FlexGrid makes it easy to customize the grid cell by cell.

Group and Analyze Data as a TreeGrid
FlexGrid is so flexible that it can be used as a super-advanced TreeView, or a "TreeGrid.” You can add hierarchical grouping to display data in a tree-like structure, complete with summaries, multiple columns, sorting, editing, and everything else you get from a rich .NET datagrid.

Virtual Mode
Improve performance and reduce load times for very large data sets with on-demand loading, where data is only retrieved as the user scrolls. This feature is also known as "Virtual Mode" and is supported in FlexGrid through the C1DataCollection.
Learn More: WinForms | WPF | Blazor
Live Demo: Blazor | ASP.NET Core
Bound or Unbound
FlexGrid supports data binding to most .NET data collections including ObservableCollection, List, Array, BindingSource, and ADO.NET objects such as DataSet and DataTable. Columns are automatically generated when data-binding.
Get native support for connecting to SQL Server and OData. Plus, connect to a variety of other sources like JSON, CSV, Dynamics and other online CRMs using ComponentOne Data Connectors.
With unbound mode, you can programmatically add rows and columns. Set cell values in code or create an empty grid for end-users to edit.

Hierarchical TreeGrid
FlexGrid supports several hierarchical data binding scenarios. You can connect two datagrids in a master-detail relationship. You can nest a child datagrid in the FlexGrid’s expandable row details. You can also transform any data collection into a hierarchical “TreeGrid” using its flexible tree node API.

Dynamic Updates
FlexGrid honors .NET dynamic data sources. Data bind to an ObservableCollection or anything that inherits the INotifyPropertyChanged interface and get dynamic updates to the data source reflected in the FlexGrid. Create live dashboards with automatic updates. Show stock prices and other rapidly updating information in your datagrid.
Paging
Enable paging to navigate through different pages of data bound to FlexGrid. Like the virtual mode and on-demand loading, paging is supported by the help of C1DataCollection. Paging can improve performance for large data sets as data is loaded per page. To enable paging, set the page size and bind a data pager control to the FlexGrid.

Live Demo: Blazor | ASP.NET Core
Virtual Mode
Virtual Mode (also known as “data virtualization” or “incremental loading”) helps manage large data sets from remote sources where loading the entire dataset at once is not practical. With Virtual Mode, we can understand the entire data set but only load smaller portions (or pages) of it at once.
Understanding the data means we can filter, sort, and scroll the data as if the entire data set existed on the client.
