'Declaration
 
<C1DescriptionAttribute("Fires before a subtotal row is added to the grid.")>
Public Event BeforeSubtotal As SubtotalEventHandler

'Usage
 
Dim instance As C1FlexGridBase
Dim handler As SubtotalEventHandler
 
AddHandler instance.BeforeSubtotal, handler

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.
