Question

通过鼠标单击从ActiveX组合框中选择项目后，我希望关闭组合框并选择该项目。

这里是一个例子。

我尝试了TempCombo_Click事件，但是在TempCombo_Change事件之后将其触发。当我单击选择项目时，传递给TempCombo_Change事件的搜索字符串为空。因此，我需要一些东西来保留TempCombo_Change事件中的项目选择。

我使用对Autocomplete suggestion in Excel data validation list again中的VBA代码的修改

这是我用来生成上述示例的VBA确切代码。

Private Sub Worksheet_SelectionChange(ByVal Target As Range)
    Dim xCombox As OLEObject
    Dim xStr As String
    Dim xWs As Worksheet
    Dim xArr
    Set xWs = Application.ActiveSheet
    On Error Resume Next
    Set xCombox = xWs.OLEObjects("TempCombo")
    With xCombox
        .ListFillRange = ""
        .LinkedCell = ""
        .Visible = False
    End With
    If Target.Validation.Type = 3 Then
        Target.Validation.InCellDropdown = False
        'Cancel = True
        xStr = Target.Validation.Formula1
        xStr = Right(xStr, Len(xStr) - 1)
        If xStr = "" Then Exit Sub
        With xCombox
            .Visible = True
            .Left = Target.Left
            .Top = Target.Top
            .Width = Target.Width + 5
            .Height = Target.Height + 5
            .ListFillRange = xStr
            If .ListFillRange = "" Then
                xArr = Split(xStr, Application.International(xlListSeparator))
                Me.TempCombo.List = xArr
            End If
            .LinkedCell = Target.Address
        End With
        xCombox.Activate
        Me.TempCombo.DropDown
    End If
End Sub

Private Sub TempCombo_KeyDown(ByVal KeyCode As MSForms.ReturnInteger, ByVal Shift As Integer)
    Select Case KeyCode
        Case 9 'tab
            Application.ActiveCell.Offset(0, 1).Activate
        Case 13 'enter
            Application.ActiveCell.Offset(1, 0).Activate
    End Select
End Sub

Private Sub TempCombo_Change()
If Me.TempCombo = "" Then Exit Sub
ActiveSheet.OLEObjects(1).ListFillRange = ""
ActiveSheet.OLEObjects("TempCombo").Object.Clear
ThisWorkbook.ActiveSheet.OLEObjects("TempCombo").Activate

With Me.TempCombo
    If Not .Visible Then Exit Sub
    .Visible = False 'to refresh the drop down
    .Visible = True
    .Activate

'Dump the range into a 2D array
        Dim Arr2D As Variant
        Arr2D = [RangeItems].Value

'Declare and resize the 1D array
        Dim Arr1D As Variant
        ReDim Arr1D(1 To UBound(Arr2D, 1))

'Convert 2D to 1D
        Dim i As Integer
        For i = 1 To UBound(Arr2D, 1)
            Arr1D(i) = Arr2D(i, 1)
        Next

    Dim itm As Variant 'itm is for iterate purpose
    Dim ShortItemList() As Variant 'ShortItemList() is a variable which stores only filtered items
    i = -1
    For Each itm In Arr1D
        If InStr(1, itm, .Value, vbTextCompare) > 0 Or .Value = "" Then
            Debug.Print itm
             i = i + 1
             ReDim Preserve ShortItemList(i)
             ShortItemList(i) = itm
        End If
    Next itm
    .DropDown
End With

On Error Resume Next 'if we filter too much, there will be no items on ShortItemList
ThisWorkbook.ActiveSheet.OLEObjects("TempCombo").Object.List = ShortItemList

End Sub

TempCombo_Click事件中的这一行解决了问题：

ActiveCell.Value = ThisWorkbook.ActiveSheet.OLEObjects("TempCombo").Object.Value

哪些VBA事件可以捕获ActiveX组合框的点击值？
