What’s New in 2020 Volume 3: Blazor

We at Syncfusion have released Essential Studio 2020 Volume 3 with support for the latest available framework updates, new controls, and new features in our existing controls. This release brings some exciting new features and enhancements to our Blazor components too.

In this blog, I am going to give you a quick overview of the new features available for the Blazor platform in this Volume 3 release.

Let’s explore them!

Components moving from preview to production-ready

The following components have been developed to meet industry standards and are now production-ready:

Breaking changes

Though we tried hard to avoid breaking changes in the APIs, some situations made breaking changes inevitable. You should be aware of these changes while upgrading your Syncfusion Blazor application to Essential Studio version They primarily consist of changes in providing strongly typed support. You can find them at the following link: https://blazor.syncfusion.com/documentation/release-notes/18.3.35/?type=breaking-changes.

We believe that these changes will help you refactor your code and improve your development time when you upgrade to the new version. We apologize for any inconvenience caused.

However, we were keen to introduce only necessary API breaks and to ensure the backward compatibility of existing features and their behaviors.

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


WebAssembly performance improvement in Data Grid

The performance of the DataGrid control features in WebAssembly (WASM) applications has been improved by avoiding unnecessary component rendering and rendering after Data Grid events. The features with improved performance are:

  • Selection
  • Column resizing
  • Filtering
  • Editing
  • Row drag and drop
  • Column chooser
  • Column menu
  • Toolbar
  • Submenu filter in column menu


The TreeGrid control has the following new features in this release.

Row drag and drop

This feature allows dragging and dropping TreeGrid rows within the control, between it and another Tree Grid control, or to any other custom components. This feature helps you change the row positions dynamically in the UI.

Virtual scrolling

This feature allows the user to load large amounts of data without any performance degradation. It is an alternate way of paging in which the data is loaded while scrolling vertically.

Support for ExpandoObject-type data

The Volume 3 release provides support to bind ExpandoObject-type data to the TreeGrid control. This is helpful when the model type of the data is unknown during compile time. This feature also helps users perform data operations and CRUD actions in the ExpandoObject-type data.

MultiSelect Dropdown

Material-style filled appearance

This feature renders the MultiSelect Dropdown control in a filled style, which is the latest Material design.
