DevExpress Blazor Grid supports multiple data edit modes:
Inline Edit FormThe Grid displays the edit form instead of the edited data row.Pop-Up Edit FormThe Grid displays the edit form in a pop-up window.Inline Edit RowThe Grid displays inline editors instead of the edited row.Cell EditingThe Grid displays an in-place editor instead of focused cell content. Unlike other modes, the Grid in EditCell mode allows users to click a data cell to edit it. The Grid validates and saves all cell values simultaneously when focus leaves the edited row.Batch EditingYou can implement batch data editing based on the EditCell mode. Batch data editing allows users to accumulate changes in memory and post them to the database when desired.

The DevExpress Blazor Grid ships with the following UI elements that allow users to filter data:
Column Filter MenuThe Excel-inspired filter menu displays unique column values as a checklist with a Select All option. An integrated search box is also available. You can modify the value list or use a template to customize the menu.Filter RowThe filter row displays in-place editors where users can type filter values. The grid can filter data by value or display text.Filter Panel and Filter BuilderThe filter panel displays the current filter condition and allows users to deactivate/clear it. Users can click this filter condition to open the filter builder dialog. In the dialog, they can edit and combine filter criteria applied to Grid columns.Search BoxUsers can type text in the search box to filter and highlight data.Semantic SearchDevExpress data-aware components (including Grid) support semantic search integration. You can modify the demo source code as needed.
You can also filter Grid data in code using criteria operator syntax.

You can compute summaries across all Grid records (total summaries) or for individual groups (group summaries).
The Grid includes predefined aggregate functions: Sum, Min, Max, Avg, and Count. In addition to these functions, you can implement custom summary algorithms.

Specify the size mode to display Grid elements (for instance, text size and row height) and built-in components (for instance, pager and buttons) in small, medium, or large predefined sizes.
You can customize the appearance of most Grid UI elements based on custom conditions.

Users can access every UI element in the Grid with a keyboard. Keyboard navigation is implemented on the client and works seamlessly even in Blazor Server apps with a slow connection.
Note
Keyboard support allows users to interact with application content in cases they cannot use a mouse or they rely on assistive technologies (like screen readers or switch devices). Refer to the Accessibility help topic for information on other accessibility areas that we address.

The DevExpress Layout Breakpoint component allows you to adapt page layouts to different screen sizes. You can modify the grid layout (for instance, add and hide columns) when a screen size breakpoint is activated.
The DevExpress Blazor Grid supports drag-and-drop operations. You can reorder rows and move them between components.

Blazor Grid automatically displays a loading panel when you open a filter menu with many unique items or execute a time-consuming export operation.
In other cases, you can use our DevExpress Loading Panel component to display a loading indicator; for example, when Grid fetches data from server.
The Grid component’s UI elements such as labels, context menus, and error messages are displayed in English. Localization automatically adapts the component to the user’s preferred language.
DevExpress components include predefined satellite resource assemblies for German, Spanish, and Japanese. Use the DevExpress Localization Service to create and download a custom set of satellite assemblies, and modify resources.
