A .NET datagrid is a feature-rich control for displaying data in a tabular format. Its various functionalities include data binding, editing, Excel-like filtering, custom sorting, aggregating rows, selection, and support for Excel, CSV, and PDF formats.

Why Choose FlexGrid?

Familiar, Excel-Like Experience

ComponentOne's .NET datagrid, FlexGrid delivers features similar to Microsoft Excel, such as cell selection and editing, so your grids will be intuitive and your end-users will be more productive.

Cross-Platform Compatibility

The same feature-rich datagrid is supported across every .NET platform: WinForms, WPF, WinUI, UWP, Blazor, ASP.NET MVC, Xamarin, MAUI and Wijmo JavaScript.

Flexible, Extensible API

Most .NET datagrids will get you 70% of the way there, but FlexGrid's superior flexibility helps developers achieve 100% of their requirements.

Great for Working With Large Data Sets

FlexGrid is designed to aid large data sets with features like grouping, aggregation, and on-demand loading with virtual mode supported in most platforms.

All-in-One Data Management

FlexGrid is primarily used for editing, visualizing, and analyzing tabular data, and is packed with features that data entry and business analysts will love.

10x Faster and Small Footprint

FlexGrid is up to 10x faster at loading and scrolling than other .NET datagrids. Plus its modularized assemblies won't bloat your app with features you don't need.

Data Bound or Unbound

Get started quickly with automatic data binding to .NET data source objects or custom business objects. FlexGrid also supports an unbound mode, giving you complete control over creating each row, column, and cell value.

.NET Datagrid custom cells

.NET Datagrid cell editors

Cell Editors

ComponentOne's .NET datagrid, FlexGrid provides several built-in editors to enable efficient in-cell editing for numbers, dates, checkboxes, and data-mapped combo-boxes. Or use any control to provide a custom editor.

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 "just-in-time data loading" and is supported in FlexGrid through the DataCollection component.

.NET Datagrid filtering

Excel-like Filtering

Enable filtering on any column's data by condition or value. FlexGrid supports drop-down filters in the column headers like Microsoft Excel with special filter editors for different data types.

.NET Datagrid searching


FlexGrid allows you to perform full-text filtering, or searches, on your data to show all matching instances found in the grid. Search the entire grid or just a specific column and then highlight all matching occurrences.

C# Datagrid filter row

Filter Row

Display a traditional filter row at the top of the .NET datagrid to allow filtering on multiple columns.

FlexGrid is so flexible that it can be used as a super-advanced TreeView. As 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.

Additional Features

Multi-Column Sorting

FlexGrid supports sorting, ascending, and descending, by clicking on the column headers. It also supports sorting by multiple columns.

Grouping and Summaries

Group data in FlexGrid to organize and analyze data more precisely. Customize the text displayed in header rows. FlexGrid can also aggregate the data to display summarized information for each group.

Detail Row

Drill into a row of data to show more details inside a collapsible panel. You can display an input form, a child data grid, or anything else within the detail row.

Column Reordering

FlexGrid allows users to modify the column order by dragging and dropping their headers. Save and persist the layout for future runs of the application.

Cell Merging

ComponentOne's C# datagrid FlexGrid supports content-driven cell merging. This allows you to merge matching adjacent cells across columns and down rows. Merge header cells, create custom cell merging rules, and set restrictions on how FlexGrid merges cells.

Adaptive Column Sizing

FlexGrid allows you to specify column sizing in code, as well as allow users to resize columns at runtime. Additionally, columns can be set to proportionally fill the space (also known as "star sizing").

Freezing and Pinning

FlexGrid offers Excel-like row and column freezing and pinning. This allows users to keep rows and columns in view as they navigate the content of the datagrid. The difference is pinning allows any column to be frozen.


Get Excel-like cell selection across rows and columns. Configure the selection mode per your requirements. FlexGrid also has mobile selection solutions such as intuitive touch support and checkbox support.

Hover Styles

Highlight cells as the end-user hover over them with the mouse. Configure the hover cell style to appear over single cells, entire rows, or entire columns.

Hierarchical Data Binding

View hierarchical data through both a master-detail model and through the use of row details. Drill down into data by displaying it in an additional or nested FlexGrid.

Live Updates

Create live datagrid displays and dashboards with automatic updates. Show stock prices and other rapidly updating information in your datagrid.


Handle Arabic, Hebrew, and other right-to-left languages with the globalized FlexGrid. You'll not only be able to select the language that FlexGrid uses to display its data, but also format how it displays dates and numbers.

Add New Row

Add a new row to the database with a tap or click. Adding a blank row to the .NET datagrid allows users to add more rows of data.


Validate data entry with built-in formatting and error detection, or use unobtrusive validation to validate as the user types.


To improve performance you can enable paging rather than vertical scrolling. Set page length and scroll ahead or back to pages using the data pager control.

Import & Export to Excel

If your business relies on Excel for data management, you can use FlexGrid to both import XLSX files, as well as export your FlexGrid data into an XLSX file to view in Excel. Choose how to preserve formatting. You can also export only selected data.

Export to PDF

FlexGrid supports exporting content with formatting to PDFs using our PDF DocumentSource component. This allows you to export the datagrid as a quick and easy report.


FlexGrid lets you print the grid and perform various basic and advanced print settings using its built-in methods and properties. Plus, our special PrintDocument component enables advanced printing techniques.
