Specifies options configuring the load panel.
When PivotGrid operates with a large number of records or uses a remote storage as a data source, loading data takes time. As data is being prepared, PivotGrid displays a load panel.
The load panel consists of a pane, a loading indicator and a text. You can specify whether the pane or loading indicator must be displayed using the showPane or showIndicator options respectively. The text displayed by the load panel can be specified using the text option. Also, you can change the height or width of the load panel using the corresponding options of the loadPanel configuration object.
Since the grid load panel is practically the DevExtreme LoadPanel widget, you can specify any option belonging to this widget in the loadPanel object.
Specifies the URL pointing to an image that will be used as a load indicator.
