Remarks

This property is considered by a grid control that visualizes the current List View in a Windows Forms application.

The total summary value is displayed within the grid footer under the column, if the List View node’s IModelListView.IsFooterVisible property is set to true.

By default, this property is set to SummaryType.None.
