Freeze as fixed

We have introduced a new column freezing mode known as Fixed, in addition to the existing Left and Right modes, within the column settings using the freeze property. This Fixed mode locks columns in place, ensuring their visibility during horizontal scrolling.

Drag and drop between groups

We have added functionality to drag and drop grid rows between different groups within the DataGrid.

DataTable binding

This feature enables the binding of a DataTable directly as a data source to the Blazor DataGrid. It also facilitates the execution of various data operations, including sorting, filtering, paging, aggregations, grouping, and searching, in addition to offering support for CRUD actions.

Pager improvements

The Pager dropdown now has adaptive support, letting it dynamically render on mobile and tablet devices alongside the Pager component. The Pager message element now adjusts its rendering based on the screen size, ensuring a more responsive and user-friendly experience.

Gantt Chart

The new features included in the Blazor Gantt Chart are as follows.

Virtualization using overscan count

Now, you can use the OverscanCount property to reduce the frequency of rendering while scrolling in the Gantt Chart. This property is used to render additional items in the DOM before and after the visible items (based on the page size) during virtual scrolling and initial rendering.

Action begin and complete events

New event support was introduced for actions performed within the Gantt Chart. These new events expand your ability to tailor and enhance your interactions within the Gantt Chart, providing you with more control and flexibility:

  • Sorting: The event callback is invoked before a sorting action is performed, a column is removed from sorting in the Gantt Chart, or when the sort column direction changes from ascending to descending or vice versa.
  • Sorted: The event callback is raised after the sorting action is performed in the Gantt Chart.

PDF Viewer

The Blazor PDF Viewer supports new, user-friendly features.

Mobile annotation toolbar

We’ve added support for an annotation toolbar on mobile devices. With this feature, users can perform various actions, such as adding, modifying, removing, and commenting on annotations within PDF documents directly from their mobile devices.

Keyboard support enhancements

We implemented keyboard-based navigation options to enhance the user experience, enabling individuals to navigate through the PDF Viewer more efficiently.

TreeGrid

The Blazor TreeGrid has the following updates.

Virtualization with overscan count

Like the Blazor Gantt Chart, TreeGrid also supports the OverscanCount property to reduce the frequency of rendering during scrolling. This property is used to render additional items in the DOM before and after the visible items (based on the page size) during virtual scrolling and initial rendering.

Action begin and complete events

New events are supported for actions performed within the TreeGrid. These new events significantly expand your ability to tailor and enhance your interactions within the tree grid, providing you with more control and flexibility:

  • Sorting: An event that is invoked before a sorting action is performed, a column is removed from sorting in the TreeGrid, or when the sort column direction changes from ascending to descending or vice versa for the same column.
  • Sorted: An event callback that is raised after a sorting action is performed in the TreeGrid.

Synchronizing charts

We’ve provided support for synchronizing the tooltips, zooming and panning, crosshairs, highlights, and selection features across numerous charts.

Refer to the following code example. In it, we display a synchronized tooltip using the ShowTooltip and HideTooltip methods.

@code
{
     public SfChart Chart;
     void ShowTooltip()
     {
         Chart.ShowTooltip("Gold", 40);
     }
     void HideTooltip()
     {
         Chart.HideTooltip();
     }
}

Blazor radial tree diagram

The Blazor Diagram component now has radial tree layout support. A radial tree layout is a diagram that presents information in a hierarchical structure, with a central node at the core of the diagram. The central node represents the main concept or topic, and branches extend outward in a radial fashion, creating a tree-like structure.
