Worksheet Object Events
Events on sheets are enabled by default. To view the event procedures for a sheet, right-click the sheet tab and click View Code on the shortcut menu. Select one of the following events from the Procedure drop-down list box.
Worksheet-level events occur when a worksheet is activated, when the user changes a worksheet cell, or when the PivotTable changes. The following example adjusts the size of columns A through F whenever the worksheet is recalculated.
Some events can be used to substitute an action for the default application behavior, or to make a small change to the default behavior. The following example traps the right-click event and adds a new menu item to the shortcut menu for cells B1:B10.
Private Sub Worksheet_BeforeRightClick(ByVal Target As Range, _ Cancel As Boolean) For Each icbc In Application.CommandBars("cell").Controls If icbc.Tag = "brccm" Then icbc.Delete Next icbc If Not Application.Intersect(Target, Range("b1:b10")) _ Is Nothing Then With Application.CommandBars("cell").Controls _ .Add(Type:=msoControlButton, before:=6, _ temporary:=True) .Caption = "New Context Menu Item" .OnAction = "MyMacro" .Tag = "brccm" End With End If End Sub
