Whats new in 2020 volume 2 - Blazor

What’s New in 2020 Volume 2: Blazor

Syncfusion is glad to announce the availability of Essential Studio 2020 Volume 2. This release brings exciting new features and enhancements in our Blazor components.

In this blog, I am going to give you a quick overview of the new features available for the Blazor platform in this Volume 2 release.

Components moving from preview to production-ready

The following components have been developed to meet industry standards. They are now marked as production-ready components for Blazor:

Major performance improvements

We have significantly improved the performance of several of our major components, including the DataGrid. Here are some actual metrics showing that the performance for initial loading and other major operations improved by over four times.

Grid performance table

Grid with 6 columns, 5000 rows – ondemand paging enabled Web Assembly application Web Assembly applicationServer application Server application
Action18.1.5918.2.0.44 18.1.5918.2.0.44
Initial loading (including script loading)~11350ms ~3100ms~1120ms~350ms
Grouping (single column)~1701ms ~1630ms~150ms~50ms
UnGrouping (single column)~440ms ~450ms~180ms~45ms
Filter set contains. (single column)~720ms ~710ms~65ms~30ms
Clearing filter~450ms ~460ms~120ms~40ms
Sorting (string column)~770ms ~745ms~110ms~45ms

All the above performance improvements were made possible by further reducing the amount of JavaScript code in our components. These improvements were made as part of our earlier commitment to remove dependency on JavaScript as much as possible.

The dependence on JavaScript was even completely eliminated in some components, like the Button and Calendar, and reduced by over 10x in components like the DataGrid and TreeGrid. Some of the related improvements include introducing strongly typed APIs and improved rendering and UI interaction performance.

All of the these improvements have been completed for the components listed below. The remaining components will receive these improvements in the next (Volume 3) release.


Breaking changes

Though we tried hard to avoid breaking changes in the APIs, some inevitable situations forced us to do so. Here are the breaking changes you should be aware of when upgrading your Syncfusion Blazor application to Essential Studio version

The breaking changes primarily consist of changes in providing strongly typed support. The changes can be found in the following link.


We believe that this will help you to refactor your code and improve your development time when you upgrade to this new version. We apologize for the inconvenience caused. However, we were very keen to introduce only necessary API breaks and completely assure the backward compatibility of the existing features and their behaviors.

We are happy to help you resolve any upgrade-related issues with high priority and request that you create a support ticket if you find it difficult to resolve problems related to the upgrade.

Accumulation chart types

The pivot chart in the Pivot Table now has these chart types: pie, doughnut, pyramid, and funnel.
