Add ComboBox in an Interactive UserForm in VBA

Question

I am using this tutorial (https://www.excel-easy.com/vba/examples/interactive-userform.html) for how to create an Interactive Userform that overwrites values based on a simple condition that if ID exists, then update or edit the rows.

However, this works very well for TextBox but I am struggling to add other controls from the Toolbox. Currently, I am trying to add ComboBox in the loops such that it can add values from the ComboBox.

Private Sub ComboBox1_Change()

End Sub

Private Sub CommandButton1_Click()
EditAdd
End Sub

Private Sub CommandButton2_Click()
ClearForm
End Sub

Private Sub CommandButton3_Click()
Unload Me
End Sub

Private Sub TextBox1_Change()
GetData
End Sub

Private Sub UserForm_Click()

End Sub

Private Sub UserForm_Initialize()
TextBox1.SetFocus
    ComboBox1.AddItem "One"
    ComboBox1.AddItem "Two"
    ComboBox1.AddItem "Three"
    ComboBox1.AddItem "Four"
    ComboBox1.AddItem "Five"
End Sub

Here is the module. I've tried to modify it by adding UserForm.Controls("ComboBox" & j).Value = Cells(i + 1, j).Value in the for loops, but I only get errors.

Dim id As Integer, i As Integer, j As Integer, flag As Boolean

Sub GetData()

If IsNumeric(UserForm.TextBox1.Value) Then
    flag = False
    i = 0
    id = UserForm.TextBox1.Value

    Do While Cells(i + 1, 1).Value <> ""

        If Cells(i + 1, 1).Value = id Then
            flag = True
            For j = 2 To 6
                UserForm.Controls("TextBox" & j).Value = Cells(i + 1, j).Value
                UserForm.Controls("ComboBox" & j).Value = Cells(i + 1, j).Value
            Next j
        End If


        i = i + 1

    Loop

    If flag = False Then
        For j = 2 To 6
            UserForm.Controls("TextBox" & j).Value = ""
            UserForm.Controls("ComboBox" & j).Value = ""
        Next j
    End If

Else
    ClearForm
End If

End Sub

Sub ClearForm()

For j = 1 To 6
    UserForm.Controls("TextBox" & j).Value = ""
    UserForm.Controls("ComboBox" & j).Value = ""
Next j

End Sub

Sub EditAdd()

Dim emptyRow As Long

If UserForm.TextBox1.Value <> "" Then
    flag = False
    i = 0
    id = UserForm.TextBox1.Value
    emptyRow = WorksheetFunction.CountA(Range("A:A")) + 1

    Do While Cells(i + 1, 1).Value <> ""

        If Cells(i + 1, 1).Value = id Then
            flag = True
            For j = 2 To 6
                Cells(i + 1, j).Value = UserForm.Controls("TextBox" & j).Value
                Cells(i + 1, j).Value = UserForm.Controls("ComboBox" & j).Value
            Next j
        End If

        i = i + 1

    Loop

    If flag = False Then
        For j = 1 To 6
            Cells(emptyRow, j).Value = UserForm.Controls("TextBox" & j).Value
            Cells(emptyRow, j).Value = UserForm.Controls("ComboBox" & j).Value
        Next j
    End If

End If

End Sub

How can I add ComboBox into my module such that the Userform overwrites existing values if ID exists?

Answer 1

I can't provide a full answer because I don't understand enough about what you are trying to achieve - hence the various comments and queries in the code. Perhaps it gives you enough to work out what you have to do.

Dim id As Integer, i As Integer, j As Integer, flag As Boolean

Sub GetData()

If IsNumeric(UserForm.TextBox1.Value) Then 'separate check required for combobox?
    flag = False
    i = 0
    id = UserForm.TextBox1.Value

    Do While Cells(i + 1, 1).Value <> ""
        If UserForm.ComboBox1.Value = Cells(i + 1, j).Value Then 'not sure if this check is right and the j needs to be replaced with something
            'do something
            'should this be a separate flag?
        End If
        If Cells(i + 1, 1).Value = id Then
            flag = True
            For j = 2 To 6
                UserForm.Controls("TextBox" & j).Value = Cells(i + 1, j).Value
            Next j
        End If
        i = i + 1
    Loop

    If flag = False Then 'might need changing if separate flags required
        UserForm.ComboBox1.Value = ""
        For j = 2 To 6
            UserForm.Controls("TextBox" & j).Value = ""
        Next j
    End If

Else
    ClearForm
End If

End Sub
