Virtual Scrolling
The horizontal and vertical scrollbars allow users to navigate data rows within the current page or across the entire control content. When ASPxPivotGrid is bound to a large data source, loading all records takes more time and can reduce performance.
When a user scrolls pivot grid content in virtual scrolling mode, the ASPxPivotGrid control sends callbacks to load the required page dynamically. To enable this functionality, set PivotGridWebOptionsView.HorizontalScrollingMode and PivotGridWebOptionsView.VerticalScrollingMode to Virtual mode for horizontal and vertical scrolling, respectively.
In virtual mode, the vertical scroll bar can be used with the built-in pager and the ASPxPivotGrid automatically switches to the required page.
Specify the following options to ensure that virtual scrolling operates properly.
- Set the Pivot Grid height and width using the ASPxWebControl.Height and ASPxPivotGrid.Width properties respectively.
- Enable the scroll bar to use Virtual mode by changing the PivotGridWebOptionsView.VerticalScrollBarMode and PivotGridWebOptionsView.HorizontalScrollBarMode properties to Visible or Auto.
