Remarks

The WPF Spreadsheet control ships with a set of events that allow you to control the expand/collapse operations for row and column groups in a worksheet.

The following events occur when a user clicks a plus / minus symbol on the outline bar (or the Hide Detail/Show Detail button on the Data ribbon tab):

• BeforeGroupProcessing
• GroupStateChanging
• GroupStateChanged
• AfterGroupProcessing

The following events occur when a user clicks one of the outline buttons to expand/collapse row or column groups:

• BeforeOutlineButtonClick
• AfterOutlineButtonClick
• AfterGroupProcessing

The AfterGroupProcessing event fires when the expand/collapse operation is completed. The event’s IsRowGroup argument allows you to check the type of affected groups (row or column).
