Worksheet Object Events

See Also

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 the event name from the Procedure drop-down list box.

Worksheet-level events occur when a worksheet is activated or the user changes a worksheet cell. The following example adjusts the size of columns A through F whenever the worksheet is recalculated.

Private Sub Worksheet_Calculate()
    Columns("A:F").AutoFit
End Sub

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
