Question

我有4个数据验证下拉菜单，我想对每个循环使用a来遍历4个数据验证下拉菜单的所有可能值，并将结果复制到工作表中。

下拉列表位于单元格H3和H4以及U3和U4中。 H3和U3包含相同的值，而H4和U4包含相同的值。

首先，我想检查工作表中是否有数据验证列表。

然后，我要遍历4个下拉列表值的所有可能值，并将结果保存在新的工作表中！

我在stackoverflow Iterate through VBA dropdown list上找到了一个线程

并且从该线程中，我正在使用以下代码：

Sub LoopThroughList()
Dim Dropdown1, Dropdown2, Dropdown3, Dropdown4 As String
Dim Range1, Range2, Range3, Range4 As Range
Dim option1, option2, option3, option4 As Range

Dim Counter As Long

Counter = 1

' *** SET DROPDOWN LOCATIONS HERE ***
' ***********************************

    Dropdown1 = "H3"
    Dropdown2 = "H4"
    Dropdown2 = "U3"
    Dropdown2 = "U4"

' ***********************************
' ***********************************

Set Range1 = Evaluate(Range("H3").Validation.Formula1)
Set Range2 = Evaluate(Range("H4").Validation.Formula1)
Set Range3 = Evaluate(Range("U3").Validation.Formula1)
Set Range4 = Evaluate(Range("U4").Validation.Formula1)

For Each option1 In Range1
    For Each option2 In Range2
        For Each option3 In Range3
            For Each option4 In Range4

            Sheets(2).Cells(Counter, 1) = option1
            Sheets(2).Cells(Counter, 2) = option2
            Sheets(2).Cells(Counter, 3) = option3
            Sheets(2).Cells(Counter, 3) = option4
            Counter = Counter + 1
            Debug.Print option1, option2, option3, option4
            Next option4
        Next option3
    Next option2
Next option1


End Sub

我在https://www.ozgrid.com/forum/forum/help-forums/excel-general/134028-loop-through-excel-drop-down-list-and-copy-paste-the-value?t=190022上发现了另一个线程，该线程通过VBA遍历了两个数据验证下拉列表。

显式选项

Sub LoopThroughDv()
    Dim dvCell As Range
    Dim inputRange As Range
    Dim c As Range
    Dim i As Long

     'Which cell has data validation
    Set dvCell = Worksheets("Input Output").Range("I4")

     'Determine where validation comes from
    Set inputRange = Evaluate(dvCell.Validation.Formula1)

    i = 0
     'Begin our loop
    Application.ScreenUpdating = True
    For Each c In inputRange
            dvCell = c.Value
       ' Worksheets("Output").Cells(i, "A").Value = dvCell
        'Worksheets("Output").Cells(i, "A").Value = Worksheets("Input Output").Range("A1").Value
        MsgBox dvCell
        Debug.Print dvCell
        i = i + 1
    Next c
    Application.ScreenUpdating = True

End Sub

如何改进此代码？另外，是否可以将整个工作表保存在循环下？对于每个循环，我的vlookups的值都会更改，我想将信息复制到新的工作表中，最后在数据透视表中使用它。

此外，在线程loop through multiple data validation lists中找到了此代码

Sub CopyPaste()
Application.ScreenUpdating = False
Dim inputRange1, inputRange2 As Range
Dim option1, option2 As Range
Set inputRange1 = 
Evaluate(Worksheets("Scenario").Range("TabSelection").Validation.Formula1)
Set inputRange2 = 
Evaluate(Worksheets("Scenario").Range("IndexSelection").Validation.Formula1)
For Each option1 In inputRange1
Worksheets("Scenario").Range("TabSelection").Value = option1.Value
    For Each option2 In inputRange2
    ActiveSheet.EnableCalculation = True
    Worksheets("Scenario").Range("IndexSelection").Value = option2.Value
        Worksheets("Scenario").Range("CopyRange").Copy
        With Sheets("Paste").Range("A" & Rows.Count).End(xlUp).Offset(2)
            .PasteSpecial Paste:=xlPasteColumnWidths
            .PasteSpecial Paste:=xlPasteValues
            .PasteSpecial Paste:=xlPasteFormats
        End With
Next option2
Next option1
Application.ScreenUpdating = True
End Sub

我已尝试将代码最小化：

Sub LoopThroughDv()
Application.ScreenUpdating = True
Dim inputRange1, inputRange2 As Range
Dim option1, option2 As Range
Set inputRange1 = Evaluate(Worksheets("Input Output").Range("I4").Validation.Formula1)
Set inputRange2 = Evaluate(Worksheets("Input Output").Range("M4").Validation.Formula1)
ActiveSheet.EnableCalculation = True

For Each option1 In inputRange1
    ActiveSheet.EnableCalculation = True
    Debug.Print option1
    Worksheets("Input Output").Range("D10").Value = option1.Value
    For Each option2 In inputRange2
        Debug.Print option2

        Worksheets("Input Output").Range("E10").Value = option2.Value

    Next option2
Next option1

Application.ScreenUpdating = True
End Sub

Excel - Data Validation list from filtered table此线程也很有用！

我找到了另一个带有指令Determine if cell contains data validation的线程来查找数据验证单元。现在，我有了数据验证单元的地址，公式1和incelldropdown。

如何逐步浏览数据验证？

Option Explicit

Public Sub ShowValidationInfo()

    Dim rngCell             As Range
    Dim lngValidation       As Long

    For Each rngCell In ActiveSheet.UsedRange

        lngValidation = 0

        On Error Resume Next
        lngValidation = rngCell.SpecialCells(xlCellTypeSameValidation).Count
        On Error GoTo 0

        If lngValidation <> 0 Then
            Debug.Print rngCell.Address
            Debug.Print rngCell.Validation.Formula1
            Debug.Print rngCell.Validation.InCellDropdown
        End If
    Next

End Sub

我发现该代码可以实现我想要的功能，但是它仅对一个数据验证下拉列表起作用。如何修改此代码以使用2或#n下拉菜单？

Sub LoopThroughDv()
    Dim dvCell As Range
    Dim inputRange As Range
    Dim c As Range
    Dim i As Long

     'Which cell has data validation
    Set dvCell = Worksheets("Input Output").Range("I4")

     'Determine where validation comes from
    Set inputRange = Evaluate(dvCell.Validation.Formula1)

    i = 0
     'Begin our loop
    Application.ScreenUpdating = True
    For Each c In inputRange
            dvCell = c.Value
       ' Worksheets("Output").Cells(i, "A").Value = dvCell
        'Worksheets("Output").Cells(i, "A").Value = Worksheets("Input Output").Range("A1").Value
        MsgBox dvCell
        Debug.Print dvCell
        i = i + 1
    Next c
    Application.ScreenUpdating = True

End Sub

更新2018年7月24日：

我仍在尝试遍历4个数据验证列表，有人可以帮助我修改下面的代码以使用2个数据验证列表吗？

Option Explicit

Sub LoopThroughValidationList()
    Dim lst As Variant
    Dim rCl As Range
    Dim str As String
    Dim iX As Integer

    str = Range("B1").Validation.Formula1
    On Error GoTo exit_proc:
    If Left(str, 1) = "=" Then
        str = Right(str, Len(str) - 1)
        For Each rCl In Worksheets(Range(str).Parent.Name).Range(str).Cells
            Range("B1").Value = rCl.Value
        Next rCl
    Else
        lst = Split(str, ",")
        For iX = 0 To UBound(lst)
            Range("B1").Value = lst(iX)
        Next iX
    End If
    Exit Sub
exit_proc:
    MsgBox "No validation list ", vbCritical, "Error"
End Sub

即使使用INDEX和MATCH的命名范围无效，此代码仍将起作用。

ExtractDataValidationList：Sub

Sub ExtractDataValidationList(Source As Range, Optional TargetWorkSheet As Worksheet)
    Dim cell As Range, rValidation As Range
    Dim list As Object, item As Variant, values As Variant
    On Error Resume Next
    Set rValidation = Source.SpecialCells(xlCellTypeAllValidation)
    On Error GoTo 0

    If rValidation Is Nothing Then
        MsgBox "No Data Validation Found"
    Else
        Set list = CreateObject("System.Collections.ArrayList")
        For Each cell In rValidation
            On Error Resume Next
            values = Range(cell.Validation.Formula1).Value
            If Err.Number <> 0 Then values = Split(cell.Validation.Formula1, ",")
            On Error GoTo 0

            For Each item In values
                If Not list.Contains(item) Then list.Add item
            Next
        Next

        If list.Count = 0 Then
            MsgBox "No Items in Data Validation Formula1"
        Else
            list.Sort
            If TargetWorkSheet Is Nothing Then Set TargetWorkSheet = Worksheets.Add
            TargetWorkSheet.Range("A1").Resize(list.Count).Value = WorksheetFunction.Transpose(list.ToArray)
        End If
    End If

End Sub
