[英]Excel VBA add item to a programatic ComboBox when other ComboBox Change
I add a new page in Multipage1 programmatically我以编程方式在 Multipage1 中添加一个新页面
Private Sub CommandButton3_Click()
Dim i As Integer
i = MultiPage1.Pages.Count
MultiPage1.Pages.Add.Caption = "Guarantee " & i
Then I would like my new page containing 3 ComboBoxes and the ComboBox1 will list the item in the table on my worksheet name "LeftTB", here is the code.然后我想要我的新页面包含 3 个 ComboBoxes,ComboBox1 将在我的工作表名称“LeftTB”上列出表中的项目,这是代码。
For r = 1 To 3
Set myCB = MultiPage1.Pages(i).Controls.Add("Forms.ComboBox.1", "ComboBox" & r, 1)
With myCB
.Width = 150
.Height = 18
Select Case r
Case Is = 1
.Left = 54
.Top = 156
'add item to combobox1
Dim rng, cl As Range
'LeftTB is the name of Table contain Data
Set rng = Range("LeftTB")
For Each cl In rng
.AddItem cl.Value
Next cl
Case Is = 2
.Left = 252
.Top = 156
Case Is = 3
.Left = 54
.Top = 180
End Select
End With
Next r
End Sub
It works fine to add value in ComboBox1 by this code.通过此代码在 ComboBox1 中添加值可以正常工作。 For the item in ComboBox 2, it depends on the value of the ComboBox1 as the code below.
对于 ComboBox 2 中的项目,它取决于 ComboBox1 的值,如下代码所示。
Private Sub ComboBox1_Change()
Dim rng, cl As Range
'The CenterTB is the table in my worksheet with two columns. The first column (SubD) contains the same data as table "LeftTB" and the next column is the item I would like to add to ComboBox2
Set rng = Range("CenterTB[SubD]")
For i = 1 to me.MultiPage1.Pages.Count
me.MultiPage1.Pages(i).Controls("ComboBox2").Clear
For Each cl In rng
If cl.Value = me.MultiPage1.Pages(i).Controls("ComboBox1").Text Then
me.MultiPage1.Pages(i).Controls("ComboBox2").AddItem cl.Offset(0, 1).Value
End If
Next cl
Next i
End Sub
However, it does not work when ComboBox1 is programmatic.但是,当 ComboBox1 是编程时,它不起作用。 I have no idea to detect the change procedure of Combobox1 when it is programmatic.
我不知道在编程时检测 Combobox1 的更改过程。
Can someone provide me the solution?有人可以为我提供解决方案吗?
When creating controls on the fly, VBA does not automatically create their Events!在动态创建控件时,VBA 不会自动创建它们的事件!
There are two ways to do that.有两种方法可以做到这一点。 To create a events wrapper class, or simpler, in case of a known number of controls to be added (your case) to previously declare the controls in a specific way:
要创建事件包装器 class 或更简单,如果要添加已知数量的控件(您的情况)以先前以特定方式声明控件:
Option Explicit
Private WithEvents ComboBox1 As MSForms.ComboBox
Private WithEvents ComboBox2 As MSForms.ComboBox 'possible to use its events, too
Private WithEvents ComboBox3 As MSForms.ComboBox 'possible to use its events, too
Private Sub btCreateCmb_Click()
Dim myCB As MSForms.ComboBox, r As Long
For r = 1 To 3
Set myCB = MultiPage1.Pages(i).Controls.Add("Forms.ComboBox.1", "ComboBox" & r, 1)
With myCB
.Width = 150
.Height = 18
Select Case r
Case Is = 1
Set ComboBox1 = myCB 'added to Set your first combo
.Left = 54
.Top = 156
'add item to combobox1
Dim rng, cl As Range
'LeftTB is the name of Table contain Data
Set rng = Range("LeftTB")
For Each cl In rng
.AddItem cl.Value
Next cl
Case Is = 2
Set ComboBox2 = myCB 'added to Set your second combo
.Left = 252
.Top = 156
Case Is = 3
Set ComboBox3 = myCB 'added to Set your third combo
.Left = 54
.Top = 180
End Select
End With
Next r
End Sub
Private Sub ComboBox1_Change()
MsgBox "Changed 1..."
End Sub
If you exactly followed the above suggestions, It should be surely triggered!如果您完全按照上述建议进行操作,它肯定会被触发!
Now, you can put in its event code whatever you need...现在,您可以根据需要放入其事件代码...
