Excel VBA - 将值插入多列组合框 [英] Excel VBA - inserting values into multicolumn combobox

问题描述

我在 Excel 的用户表单上有两个组合框.当我选择第一个组合框时，它会过滤当前工作表上的行并在组合框 2 中显示值.

I've got two combo boxes on a user form in Excel. When I select the first combo box, it filters the rows on the current worksheet and displays the values in combobox2.

我希望 combobox2 成为一个多列组合框，以便我可以将多个值从一个工作表复制并粘贴到另一个工作表，但我无法将多个值输入到 combobox2 中.这是我一起破解的代码.当我更改组合框 1 中的值但组合框 2 显示单个值时，我能够过滤结果:

I would like combobox2 to be a multicolumn combobox so I can copy and paste multiple values from one worksheet to another but I can't get multiple values into combobox2. This is the code I've hacked together. I am able to filter the results when I change the value in combobox1 but combobox2 is displaying a single value:

Private Sub ComboBox1_Change()
Me.ComboBox2.Clear

'filter the results in combo box 2 when the user selects the different         options in combo box 1
    Dim wb As Workbook
    Dim ws As Worksheet
    Dim copyFrom As Range, aCell As Range
    Dim lRow As Long
    Dim strSearch As String

Set wb = ThisWorkbook
'~~> Set this to the worksheet where the autofilter is applied
Set ws = wb.Worksheets("RegEvents")

'~~> Filter Column on text in Combo box 1
strSearch = ComboBox1.Value

With ws
    '~~> Remove any filters
    .AutoFilterMode = False

    With .Range("RegEvents_WorksheetData")
        .AutoFilter Field:=Range("RegEvents_Action").Column, Criteria1:="="     & strSearch

        '~~> Identify the filtered range
        Set copyFrom = .Offset(1, 0).SpecialCells(xlCellTypeVisible)

        '~~> Add values from filtered search to Combobox2
        For Each aCell In copyFrom

If aCell.Value <> "" And aCell.Column = Range("RegEvents_EventID").Column Then
ComboBox2.AddItem (aCell.Value)
End If

If aCell.Value <> "" And aCell.Column = Range("RegEvents_Event").Column Then
ComboBox2.AddItem (aCell.Value)
 End If

     Next
    End With

    '~~> Remove any filters
    .AutoFilterMode = False
End With
End Sub

Private Sub UserForm_Initialize()
'Used to create an array
Dim listItems As Variant
    Me.ComboBox1.ListIndex = -1 ' -1 = no items selected

Label1.Caption = "Action"
Label2.Caption = "Event"

listItems = Range("CatogriesAction")

With ComboBox1
'Loops through the array and only adds non blank values to the combo box
For i = 1 To UBound(listItems, 1)
 If Len(Trim(listItems(i, 1))) > 0 Then
 .AddItem listItems(i, 1) ' populate the listbox
 End If
 Next i

 .ListIndex = 0 ' -1 = no items selected, set to 0 to select the first item
 End With

'Set number of columns for combobox 2
With Me.ComboBox2
 .ColumnCount = 2
 .BoundColumn = 2
 .ColumnWidths = ".5 in; .5 in"
 End With

End Sub

推荐答案

对于多列组合框，您必须使用 .List 属性来填充列数据.所以在你的情况下:

For multi column ComboBoxes you must use the .List property to fill the columns data. So in your case:

For Each aCell In copyFrom

 If aCell.Value <> "" And aCell.Column = Range("RegEvents_EventID").Column Then
  ComboBox2.AddItem aCell.Value
  lRow = aCell.Row
 End If

 If aCell.Row = lRow And aCell.Column = Range("RegEvents_Event").Column Then
  With ComboBox2
   .List(.ListCount - 1, 1) = aCell.Value
  End With
 End If

Next

使用 .TextColumn 在文本字段中显示两列的完整示例.要求:带有 ComboBox1 的用户表单

A complete Example using .TextColumn displaying both columns in the text field. Requirements: UserForm with ComboBox1

Private Sub UserForm_Initialize()

 With Me.ComboBox1
  .ColumnCount = 3
  .BoundColumn = 2
  .TextColumn = 3
  .ColumnWidths = "1cm;1cm;0"
 End With

 RegEvents_EventID = [{1;2;3;4;5}]
 RegEvents_Event = [{"Event 1";"Event 2";"Event 3";"Event 4";"Event 5"}]

 For i = LBound(RegEvents_EventID) To UBound(RegEvents_EventID)
  With Me.ComboBox1
   .AddItem RegEvents_EventID(i, 1)
   .List(.ListCount - 1, 1) = RegEvents_Event(i, 1)
   .List(.ListCount - 1, 2) = RegEvents_EventID(i, 1) & " " & RegEvents_Event(i, 1)
  End With
 Next

End Sub
