Modern web applications rely heavily on data. Whether you’re displaying reports, managing records, or building dashboards, your grid component needs to be fast, flexible, and easy to work with.

If a Blazor DataGrid only shows rows and columns, it quickly becomes a limitation as applications grow in data volume and interaction complexity. Developers today expect smooth scrolling with large datasets, intuitive editing, powerful filtering, and layouts that adapt naturally to different screens.

That’s where Syncfusion^® Blazor DataGrid stands out, as applications grow in data volume and interaction complexity.

In this post, we’ll walk through the most important features, grouped in a way that’s easy to understand and aligned with how developers actually explore a grid component.

High-performance data handling for large datasets

Large datasets are common in modern applications, and users expect smooth scrolling, fast loading, and responsive interaction regardless of data size.

When working with real-world data, performance is non-negotiable. The grid must remain fast and responsive even when datasets grow into millions or more. Syncfusion Blazor DataGrid is designed to handle this efficiently without forcing you to write complex optimization logic.

1. Virtual Scrolling

Virtual scrolling renders only the rows currently visible on the screen. As users scroll, the grid dynamically loads and unloads rows. This keeps the DOM light, reduces memory usage, and ensures smooth scrolling even with very large datasets.

2. Infinite Scrolling

Infinite scrolling loads data incrementally as users reach the end of the scroll bar. Instead of loading everything upfront, the grid fetches records on demand, creating a seamless browsing experience that feels natural and responsive.

3. Column Virtualization

When working with many columns, column virtualization ensures that the grid renders only visible columns. As users scroll horizontally, additional columns are loaded on demand—resulting in faster rendering and better overall performance.

4. Lazy Load Grouping

Grouping large datasets can be expensive if everything loads at once. Lazy load grouping solves this by loading only top-level groups initially. The grid fetches child records when you expand a group, keeping performance predictable and fast.

5. Paging

Paging divides data into manageable chunks, making large datasets easier to navigate. It improves load time, reduces UI clutter, and allows users to focus on specific data ranges.

Real-Time CRUD editing with backend synchronization

Editing data should feel simple and reliable, whether users are updating a single row, correcting multiple values, or working through structured forms.

The Syncfusion Blazor DataGrid fully supports Create, Read, Update, and Delete (CRUD) operations using both local collections and remote data sources, including REST APIs. When connected through a data manager, it automatically synchronizes updates with the backend.

Editing modes

• Inline editing: Edit values directly within a row for quick updates.
• Batch editing: Modify multiple cells and save all changes together.
• Dialog editing: Edit records in a popup form for more structured input.

Built-in command buttons (Add, Edit, Save, Delete) provide a familiar editing experience.

This flexibility allows developers to choose the right editing experience based on workflow complexity and user expectations.

Advanced filtering and search with an Excel-like experience

Filtering plays a major role in how users explore and understand data. Syncfusion Blazor DataGrid offers filtering support that feels familiar, powerful, and easy to use.

1. Excel-Style Filtering

The Excel filter provides a user interface similar to Microsoft Excel, allowing users to quickly filter values using checkboxes, search boxes, and conditions. The grid generates filter options dynamically based on column data, reducing setup effort.

2. Wildcard & Like Filtering

Wildcard and Like operators allow flexible string searches using familiar patterns. These filters are ideal when users don’t know the exact value they’re searching for.

3. Diacritics Filtering

For datasets containing accented characters, diacritics filtering lets you control whether accents are ignored or respected during searches, making filtering more accurate across different languages.

4. Searching

The Syncfusion Blazor DataGrid provides built-in search capabilities that complement filtering, allowing users to quickly locate records across the entire grid using a search keyword.

Flexible column management and layout control

The Blazor DataGrid offers flexible column management, allowing developers to shape how data is presented and how users interact with it. You can auto-generate columns from a data source or define them explicitly, apply formatting, enable text wrapping, and control visibility using the column chooser and column menu. These capabilities make it easy to adapt the grid layout as data structures evolve or user requirements change.

Data Organization: Sorting, Grouping, and Aggregation

The Blazor DataGrid makes it easy to organize and summarize data using built-in sorting, grouping, and aggregation features. These tools help users quickly explore large datasets, identify patterns, and view key values without complex configuration.

1. Grouping

Group records by one or more columns using drag-and-drop. Grouped data can be expanded or collapsed, making large datasets easier to navigate and understand.

2. Aggregation

Display summary values such as totals, averages, minimums, or maximums. Aggregates can appear in overall summary rows, group summaries, or group caption rows.

3. Sorting

Sort data in ascending or descending order by clicking column headers. The grid also supports multi-column sorting and custom sorting logic for advanced scenarios.

Column Pinning and Sticky Headers

Large datasets often require users to compare values across columns or scroll through long lists. These layout features ensure important data stays visible at all times.

1. Frozen Columns and Rows

Frozen rows do remain visible at the top while virtual scrolling. Frozen columns can be pinned to the left or right, allowing horizontal scrolling without losing context. This is especially useful when comparing values across wide grids.

2. Drag-and-Drop column freezing

Users can dynamically move columns into or out of the frozen area using a simple drag-and-drop separator. This interactive behavior feels familiar to anyone who has used spreadsheet tools like Excel.

3. Sticky Headers

Sticky headers keep column headers visible as you scroll, making large datasets easier to understand and navigate.

Data Selection and Row interaction

The Blazor DataGrid provides flexible selection features that let users efficiently interact with rows and cells using mouse, keyboard, or touch gestures.

1. Selection modes

You can control how data is selected based on your application needs:

• Row selection: Select entire rows (default behavior)
• Cell selection: Select individual cells
• Row and cell selection: Enable both simultaneously

2. Drag selection

Select multiple rows or cells by dragging across the grid using mouse or touch input. This is ideal for bulk operations without relying on keyboard shortcuts.

3. Checkbox selection

Enable checkbox selection in rows to easily select multiple records. This approach is useful for batch actions such as delete, export, or status updates.

End-to-end template customization

The Syncfusion Blazor DataGrid lets you customize every part of the grid using templates. You can replace or extend built-in UI for cells, headers, editors, toolbars, and more with your own components and logic.

This flexibility makes it easy to adapt the grid to your application’s design and behavior without limitations.

The available template options in our DataGrid are:

• Column template: Customizes cell content.
• Header template: Customizes header cell content.
• Row template: Customizes row content.
• Detail template: Customizes the cell content details.
• Caption template: Customizes group captions.
• Filter bar template: Customizes a particular column filter bar.
• Cell edit template: Edits a column using a custom component.
• Inline template: Renders custom components in the inline edit form.
• Dialog template: Renders custom components in the dialog edit form.
• Pager template: Renders custom components/elements with pagination.
• Footer aggregate template: Shows aggregate values in the footer cells.
• Group footer template: Shows aggregate values in the group footer cells.
• Group caption template: Shows aggregate values in the group caption cells.

Excel-like productivity features

Many users expect grid interactions to feel similar to Excel-style spreadsheet tools they already know. These features help meet those expectations.

1. AutoFill

AutoFill lets users copy values across cells by dragging, speeding up repetitive data entry and edits.

2. Clipboard support

Built-in copy and paste functionality allows users to move data efficiently using keyboard shortcuts. It supports both individual cells and larger selections, improving productivity in data-heavy scenarios.

3. Row height

Row height can be easily customized in the Syncfusion Blazor DataGrid to control data density and improve readability, especially when displaying large datasets.

High-Fidelity data export (Excel, PDF & CSV)

Exporting data should be straightforward and reliable. The Syncfusion Blazor DataGrid allows users to export data to Excel, PDF, or CSV formats, preserving formatting.

Export retains templates, styles, hierarchical data, and custom layouts, ensuring consistency between what users see in the UI and what they share externally.

Multi-Sheet & advanced Excel Export

For more complex reporting needs, the grid supports adding extra worksheets during Excel export. This allows you to include summaries, additional datasets, or metadata alongside the main grid data, all in a single file.

Responsive, touch-friendly, and adaptive UI

The Syncfusion Blazor DataGrid is built to handle both responsive and adaptive layouts, ensuring a consistent experience across desktop, tablet, and mobile devices.

1. Responsive grid behavior

The DataGrid is fully responsive and adjusts automatically when the browser window is resized. Column widths, row layout, and scrolling adapt in real time, keeping the grid usable across different screen sizes without additional configuration.

2. Adaptive UI layout

In addition to responsiveness, the DataGrid provides an adaptive UI layout that renders optimized feature interfaces based on the device type. On mobile and tablet devices, elements such as filtering, sorting, paging, column menus, and edit dialogs are displayed in touch-friendly, simplified layouts.

3. Touch-friendly interactions

All DataGrid features support touch gestures out of the box. Users can interact using taps, swipes, scrolling, and drag actions, making the grid intuitive and easy to use on touch-enabled devices.

Web accessibility and keyboard support

Accessibility is a core requirement for modern web applications. A data grid should be usable by everyone, including users who rely on assistive technologies or keyboard navigation.

The Blazor DataGrid is designed with accessibility in mind, following WAI-ARIA standards and offering full keyboard support. Screen readers can interpret grid content accurately, while high-contrast visuals improve readability for users with low vision.

You can perform every major interaction, such as sorting, selecting rows, and editing data,  using only the keyboard. This ensures smooth navigation without requiring a mouse, helping developers build inclusive and accessible applications with confidence.

Theme customization

Themes play a key role in defining the look and feel of an application. The Blazor DataGrid includes multiple built-in Sass-based themes that help applications look polished and consistent out of the box.

These themes can be easily customized by overriding Sass variables or by creating entirely new themes using the theme studio. This flexibility makes it simple to align the grid’s appearance with your brand or application design without rewriting styles from scratch.
