Public Event BeforeSubtotal As SubtotalEventHandler

'Usage
 
Dim instance As C1FlexGridBase

[C1Description("Fires before a subtotal row is added to the grid.")]
public event SubtotalEventHandler BeforeSubtotal

[C1Description("Fires before a subtotal row is added to the grid.")]
public:
event SubtotalEventHandler^ BeforeSubtotal

Subtotal rows are added when the Subtotal(AggregateEnum,Int32,Int32,Int32,Int32,String) method is invoked.

The event handler may prevent the grid from adding a particular row, or it may customize the caption, style, and aggregate value used in the new subtotal row.
