What’s New in Syncfusion Blazor Components


What’s New in Syncfusion Blazor Components

2022 Volume 2 enhances our Blazor offering with a new Pager component, production-ready Carousel and Diagram components, and improvements to the DataGrid control.


New Pager component (Preview)

The Blazor Pager component has an option to split a data set into multiple pages for a great user experience by viewing page by page using an intuitive UI. Here, navigation can be done with built-in numeric elements, drop down, and buttons that can also be customized with the help of rich APIs.

It acts intelligently and changes its UI responsively based on the dimension. It ensures that every pager element is keyboard accessible and has complete WAI-ARIA accessibility support.

The Pager comes with several built-in SASS-based themes such as Fluent, Tailwind CSS, Bootstrap 5, Bootstrap 4, Bootstrap, Material, Fabric, and high contrast that are also customizable.

End of support for .NET 5

Syncfusion Blazor components no longer support .NET 5, although we will continue to support .NET 3.1 and .NET 6. We recommend that you upgrade to .NET 6 to take advantage of new features and components in the latest release. If you are unable to update to .NET 6, you may continue to use version 20.1 in your .NET 5 projects.

Preview to production

The Blazor Diagram and Carousel components have been developed to meet industry standards. The components are now marked as production-ready for Blazor.

This feature allows users to control the stacking order (Z-Order) of the diagram elements such as nodes, connectors, and groups. Also, users can arrange the selected objects on the diagram page with its Z-order values by using the following features.

  • Bring to front - Bring the selected object in front of all other objects.
  • Bring forward - Bring the selected object forward one level so that it is hidden behind fewer objects.
  • Send to back - Send the selected object behind all other objects.
  • Send backward - Send the selected object back one level so that it is hidden behind more objects.

Z-Oder support in Blazor Diagram component

Expand and collapse

This feature allows users to show or hide child nodes in the parent-child relationship diagram either by user interaction on the nodes or programmatically.

Word Processor

Track changes - restriction type

This feature restricts users from accepting or rejecting tracked changes, while editing a Word document without any limitation.

Extending geometry type support

The Blazor Maps now supports rendering GeoJSON files with “MultiLineString”, “MultiPoint”, and “GeometryCollection” geometry types. The geometry type “MultiLineString” represents an array of two or more geographic points. The geometry type “MultiPoint” represents an array of points that renders circle markers. The geometry type “GeometryCollection” is a special type that contains various geometries as members.

PDF Library

PDF/A-4 conformance

PDF/A-4 is the latest edition of the PDF/A conformance series based on ISO 32000-2 (PDF 2.0). This new format allows non-static content in PDF documents in the form of JavaScript, so the logic of an interactive form can be stored and archived. Additionally, it simplifies the handling of digital signatures.

PDF/A-4 has the following conformance levels:

  • PDF/A-4e: This conformance level is intended for technical documents. It supports 3D models, rich media, 3D annotations, and embedded files to create a PDF/A version compatible with engineering workflows.
  • PDF/A-4f: This conformance level allows embedding files in any other format.

Now the Syncfusion .NET PDF Library supports the creation of PDF/A-4 conformance documents and the conversion of existing PDF documents to PDF/A-4 conformance.

PDF A-4 Conformance in PDF Library

RichMedia annotation

RichMedia annotations can be used to embed videos and sound files in PDF documents. The user can play the media content as part of the page content by just clicking on the video or audio. This annotation is newly introduced in PDF 2.0 to replace sound and movie annotations, which are deprecated in PDF 2.0.

Watermark annotation

The .NET PDF Library now supports the watermark annotation, which is used to show text, images, and shapes as watermark content in page graphics with a fixed size and position. It supports the following features:

  • Text, images, and graphical shapes.
  • Rotation to 0, 90, 180, and 270 degree angles.
  • Customization as a print-only watermark (annotation disappears in view mode).
  • Existing watermark annotations can be edited or removed.

HTML-to-PDF conversion enhancements

The Blink binaries have been updated to the latest version to improve the conversion quality and address security vulnerabilities in the Syncfusion HTML-to-PDF conversion library.

Pivot Table

Display grand totals at top/bottom

Display the summarized totals (grand totals) at the first or last position in the Pivot Table’s row and column axes.

Events for toolbar UI actions

UI actions in the Pivot Table’s toolbar options such as report, switch between table and chart views, show/hide totals, formatting, and show field list can now be identified using the action begin and action complete events. The action failure event is triggered when a UI action does not achieve the desired result. Overall, these events help the application interact with the user on a regular basis.

Query Builder

Complex data binding support

This feature allows users to create subfields for columns by specifying either a complex data source or nested columns.
