Remarks

You can activate column/row virtualization to optimize DevExpress Blazor Pivot Table performance when working with large datasets. Once virtual scrolling is activated, the component renders only columns/rows within the viewport (and a small buffer area). Other cells are loaded dynamically as users scroll the Pivot Table.

Use the following API members to configure virtual scrolling:

VirtualScrollingEnabledSpecifies whether virtual scrolling is active.VirtualScrollingModeSpecifies the virtual scrolling mode:

Vertical: Only rows are virtualized.
Horizontal: Only columns are virtualized.
Both or Default: Rows and columns are virtualized.

The following code activates horizontal virtual scrolling in the Pivot Table:

razor

<DxPivotTable Data="SalesData"
              VirtualScrollingEnabled="true"
              VirtualScrollingMode="PivotTableVirtualScrollingMode.Horizontal">
    <Fields>
        @*...*@
    </Fields>
</DxPivotTable>

The Pivot Table renders skeleton items while it retrieves data during scrolling operations.
