DataGridView.RowDividerDoubleClick Event
Assembly: System.Windows.Forms (in system.windows.forms.dll)
You can use this event to customize the automatic sizing behavior that occurs when a user double-clicks a row divider.
The row DividerWidth property does not extend the area in which a user can double-click. If the height of a divider has been increased through the use of this property, this event occurs when the user double-clicks the boundary between the divider and the adjacent column.
For more information about handling events, see Consuming Events.
