React Charts (forked)DevExtreme React Charts comprise 30+ UI components for data visualization, including bars, areas, lines, bubbles, pie, funnels, sparklines, treemaps, and other chart types.
NOTE
Use our DevExpress BI Dashboard to embed interactive business intelligence into your next web app.
The Web Dashboard is a data analysis UI component that you can embed into your ASP.NET Core or Angular, React, and Vue applications with .NET backend. Dashboards allow you to display multiple inter-connected data analysis elements such as grids, charts, maps, gauges, and others: all within an automatically-arranged layout.
The set of components allows you to deploy an all-in-one solution and switch between Viewer and Designer modes directly on the web client (includes adaptive layouts for tablet & mobile).
The Web Dashboard is available as a part of a Universal subscription.

Group Summaries (forked)To configure group summaries, populate the summary.groupItems array with summary configuration objects. Each object should specify a column that supplies data for summary calculation and a summaryType—an aggregate function that should be applied to this data.
Position a Group Summary
Group summaries are displayed in parentheses after the group caption. You can reposition them as follows:
Display a summary in a column
You can align a summary to its corresponding column (see the Sale Amount and Total Amount columns). To do this, enable the alignByColumn property. If you want to align a summary to a different column, specify the showInColumn property.
Display Summary Values within Group Footers
You can make a summary item display its values within group footers. To do this, enable the showInGroupFooter property. Summary items will appear within their corresponding columns (see the Total Amount column). If you want to display summaries in another column, specify the showInColumn property.
Format Summary Values
To format summary values, use the valueFormat property. This demo applies the "currency" format to summary values calculated against the Total Amount and Sale Amount columns. If you also want to add custom text to summary values, use the displayFormat property. This demo sets this property for summaries of "sum" and "count" types.
Sort Groups by Summary Values
This demo sorts groups by summary values (the number of orders). To do this, the code adds an object to the sortByGroupSummaryInfo array. The object specifies the summaryItem whose values are used to sort the group rows.

Templates (forked)The Scheduler contains the following properties used to specify custom templates globally and for individual views.
Appointment rectangle: appointmentTemplate / views[].appointmentTemplate
Tooltip: appointmentTooltipTemplate / views[].appointmentTooltipTemplate.
To customize the appointment details form, implement the onAppointmentFormOpening handler. In this demo, this handler adds custom fields to the appointment details form.
Dialog position issueDrawer is a dismissible or permanently visible panel that usually contains navigation elements.
To open or close the Drawer component in this demo, click the 'Hamburger' button. Each Drawer visibility change can adjust the layout in the following ways (see openedStateMode):
"push"
The Drawer partially displaces the view.
"shrink"
The view shrinks to accommodate the Drawer.
"overlap"
The Drawer overlaps the view.
Use the radio buttons at the bottom of this demo module to try different layout modes. You can also change the Drawer's position and revealMode properties.
Note this demo's markup. The Drawer definition encloses the view content (the formatted text). The Drawer's own content (navigation links) is set by the template property. Finally, the toolbar markup is separate from other elements.
To get started with the DevExtreme Drawer component, refer to the following step-by-step tutorial: Getting Started with Navigation Drawer.
Web API Service (forked)The PivotGrid can communicate with a Web API service. The quantity of aggregated data is irrelevant when aggregation is performed on the server. For example, the PivotGrid works with a million aggregated records in this demo.
To configure access to a Web API service from the client, use the createStore method, which is part of the DevExtreme.AspNet.Data extension. This extension also allows you to configure server-side data processing for DevExtreme components.
You should also set the remoteOperations property to true to notify the PivotGrid that data is aggregated on the server.
A 1-Click Solution for CRUD Web API Services with Role-based Access Control via EF Core
If you target .NET for your backend API, be sure to check out Web API Service and register your free copy today. The Solution Wizard scaffolds an OData v4 Web API Service (.NET 6+) with integrated authorization & CRUD operations powered by EF Core ORM. You can use OAuth2, JWT or custom authentication strategies alongside tools like Postman or Swagger (OpenAPI) for API testing.
The built-in Web API Service also filters out secured server data based on permissions granted to users. Advanced/enterprise functions include audit trail, endpoints to download reports, file attachments, check validation, obtain localized captions, etc.
To use the free Solution Wizard (which creates the Web API Service), run the Universal Component Installer from the DevExpress Download Manager and use our predefined template in Visual Studio 2022+.

Filters sync failed when postProcess on header filterTo access a Web API service from the client, use the createStore method which is part of the DevExtreme.AspNet.Data extension. This extension also allows you to process data for DevExtreme components on the server. The server-side implementation is available under the DataGridWebApiController.cs tab in the ASP.NET MVC version of this demo.
To notify the DataGrid that data is processed on the server, set the remoteOperations property to true.
