Question

基本上，我试图在UserForm上创建多个相关的动态组合框，因为它从LookupList工作表中提取值，如下所示

应如何工作：

ComboBox1 would list the company
ComboBox2 is dependent on ComboBox1
ComboBox3 is dependent on ComboBox2

示例：

ComboBox1: Company = Mercedes
ComboBox2: Mercedes Model = A Class
ComboBox3: A Class Model = AMG

我尝试了下面的代码，但卡在了ComboBox2上

Private Sub UserForm_Initialize()

'dynamically call ComboBox1 when form initialize
With Worksheets("LookupList")
ComboBox1.List = .Range("A2:A" & .Range("a" & .Rows.Count).End(xlUp).Row).Value

End With
End Sub

Private Sub ComboBox1_Change()
Dim index As Integer

'list ComboBox1 and look for dependency
index = ComboBox1.ListIndex
ComboBox2.Clear
ComboBox3.Clear

'call values in ComboBox2
Select Case index
Case Is = 0
'Calls Mercedes Car Model contents dynamically
With Worksheets("LookupList")
ComboBox2.List = .Range("C2:C" & .Range("c" & Rows.Count).End(xlUp).Row).Value
End With

Case Is = 1
'Calls BMW Car Model contents dynamically
With Worksheets("LookupList")
ComboBox2.List = .Range("G2:G" & .Range("g" & Rows.Count).End(xlUp).Row).Value
End With

End Select
End Sub

Private Sub ComboBox2_Change()

Dim index As Integer
Dim verify_data As Long

index = ComboBox2.ListIndex

verify_data = ComboBox2.ListIndex

'Calls values in ComboBox3
Select Case index

If verify_data = 0 Then
'If Mercedes A Class Model is selected from ComboBox2, list A Class model types
Case Is = 0
With Workseets("LookupList")
ComboBox3.List = .Range("D2:D" & .Range("d" & Rows.Count).End(xlUp).Row).Value
End With

End If
End Select
End Sub

Answer 1

缩短代码的一种方法是使用更好的语法对其进行重构，并将每个查找列表分配给一个命名范围。

find_package(boost_coroutine)
find_package(boost_context)

我设法解决了自己的问题，如下面的代码所示。如果有人使用较短的方法，请随时分享。

  Private Sub ComboBox2_Change()

  Dim index As Integer

  'list ComboBox2 and look for dependency
   index = ComboBox2.ListIndex
   ComboBox3.Clear

   If Me.ComboBox2.Value = "A Class" Then
   With Worksheets("LookupLists")
   ComboBox3.List = .Range("D2:D" & .Range("d" & 
   Rows.Count).End(xlUp).Row).Value

   End With
   End If

   If Me.ComboBox2.Value = "B Class" Then
    With Worksheets("LookupLists")
    ComboBox3.List = .Range("E2:E" & .Range("e" & 
    Rows.Count).End(xlUp).Row).Value

    End With
    End If
    End Sub

尝试

Private Sub UserForm_Initialize()

    Dim Ws As Worksheet
    Set Ws = Worksheets("LookupList")
    With Ws
        ComboBox1.List = .Range("A2:A" & .Range("a" & Rows.Count).End(xlUp).Row).Value
    End With
End Sub
Private Sub ComboBox1_Change()
    Dim Ws As Worksheet
    Dim rngT As Range, rngHead As Range
    Set Ws = Worksheets("LookupList")
    Set rngHead = Ws.Range("a1", "i1")


    ComboBox2.Clear
    ComboBox3.Clear

    Set rngT = rngHead.Find(ComboBox1.Value, LookIn:=xlValues, Lookat:=xlPart)
    If Not rngT Is Nothing Then
        ComboBox2.List = Ws.Range(rngT.Offset(1, 0), rngT.End(xlDown)).Value
    End If


End Sub
Private Sub ComboBox2_Change()
    Dim Ws As Worksheet
    Dim rngT As Range, rngHead As Range
    Set Ws = Worksheets("LookupList")
    Set rngHead = Ws.Range("a1", "i1")

    ComboBox3.Clear
    If ComboBox2.Value <> "" Then
        Set rngT = rngHead.Find(ComboBox2.Value, LookIn:=xlValues, Lookat:=xlPart)
        If Not rngT Is Nothing Then
            ComboBox3.List = Ws.Range(rngT.Offset(1, 0), rngT.End(xlDown)).Value
        End If
    End If

End Sub
