问题描述
我设置了一个包含多列的电子表格,其中一些列有数据验证下拉列表。我需要用户能够从下拉列表中选择多个选项。我已经使用下面的 VBA 为一列实现了这一点,但是我正在努力寻找将其应用于多列的正确方法。请有人帮忙。 目前我已经使用了“Target.Column = 9”,但是我需要将其应用于第 3、4、5、6、9 列。
Private Sub Worksheet_Change(ByVal Target As Range)
Dim Oldvalue As String
Dim Newvalue As String
Application.EnableEvents = True
On Error GoTo Exitsub
If Target.Column = 9 Then
If Target.SpecialCells(xlCellTypeAllValidation) Is nothing Then
GoTo Exitsub
Else: If Target.Value = "" Then GoTo Exitsub Else
Application.EnableEvents = False
Newvalue = Target.Value
Application.Undo
Oldvalue = Target.Value
If Oldvalue = "" Then
Target.Value = Newvalue
Else
If InStr(1,Oldvalue,Newvalue) = 0 Then
Target.Value = Oldvalue & "," & Newvalue
Else:
Target.Value = Oldvalue
End If
End If
End If
End If
Application.EnableEvents = True
Exitsub:
Application.EnableEvents = True
End Sub
提前致谢
解决方法
您可以扩展您的 If
If Target.Column = 9 or Target.Column = 3
等
但有时 Select Case
会更整洁一些。
Private Sub Worksheet_Change(ByVal Target As Range)
Dim Oldvalue As String
Dim Newvalue As String
Application.EnableEvents = True
On Error GoTo Exitsub
Select Case Target.Column
Case 3,4,5,6,9
If Target.SpecialCells(xlCellTypeAllValidation) Is Nothing Then
GoTo Exitsub
Else: If Target.Value = "" Then GoTo Exitsub Else
Application.EnableEvents = False
Newvalue = Target.Value
Application.Undo
Oldvalue = Target.Value
If Oldvalue = "" Then
Target.Value = Newvalue
Else
If InStr(1,Oldvalue,Newvalue) = 0 Then
Target.Value = Oldvalue & "," & Newvalue
Else:
Target.Value = Oldvalue
End If
End If
End If
End Select
Exitsub:
Application.EnableEvents = True
End Sub
