Hello,

I am glad to hear that you have found a solution to your problem.

As the information on the link that did not work can be found useful, I will add the snippets just in case you need them in the future:

UltraDropDown in VB:

Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
        Me.BindUltraDropDown()
End Sub

Private Sub BindUltraDropDown()

        Dim dt As DataTable = New DataTable()
        dt.Columns.Add("ID", GetType(Integer))
        dt.Columns.Add("DisplayText", GetType(String))

        dt.Rows.Add(New Object() {1, "A"})
        dt.Rows.Add(New Object() {2, "B"})
        dt.Rows.Add(New Object() {3, "C"})
        dt.AcceptChanges()

        Me.UltraDropDown1.SetDataBinding(dt, Nothing)
        Me.UltraDropDown1.ValueMember = "ID"
        Me.UltraDropDown1.DisplayMember = "DisplayText"
End Sub

Private Sub UltraGrid1_InitializeLayout(ByVal sender As System.Object, ByVal e As Infragistics.Win.UltraWinGrid.InitializeLayoutEventArgs) Handles UltraGrid1.InitializeLayout
        e.Layout.Bands(0).Columns("Int32 1").ValueList = Me.UltraDropDown1
End Sub

ValueList in VB:

Private Sub UltraGrid1_InitializeLayout(ByVal sender As System.Object, ByVal e As Infragistics.Win.UltraWinGrid.InitializeLayoutEventArgs) Handles UltraGrid1.InitializeLayout
    Dim vl As ValueList

        If (Not e.Layout.ValueLists.Exists("MyValueList")) Then
            vl = e.Layout.ValueLists.Add("MyValueList")
            vl.ValueListItems.Add(1, "A")
            vl.ValueListItems.Add(2, "B")
            vl.ValueListItems.Add(3, "C")
        End If

        e.Layout.Bands(0).Columns("Int32 1").ValueList = e.Layout.ValueLists("MyValueList")

End Sub

UltraCombo

The UltraCombo can be used as a ValueList and it has essentially the same features as UltraDropDown. However, UltraCombo is intended for use as a standalone ComboBox. So while it can be used as a ValueList, there is no reason to do so. It has no advantage over UltraDropDown and has greater overhead.

In addition to being an IValueList, the UltraCombo is also an Editor. So it can also be assigned as the EditorControl of a column. This has certain advantages over the UltraDropDown, such as the ability to use a DataFilter or provide EditorButtons. But if you are not using these features, the extra overhead of UltraCombo means that the UltraDropDown is a better choice.

If you have any further questions, please let me know.

Hello, Tihomir, I was not able to get this working. At the end I used a function that someone created internally that returns the combobox created and with that it worked, thanks.
