I have the following code:

Code:
    Private Sub CellEditorTxtResult_SetControlValue(sender As Object, e As Infralution.Controls.VirtualTree.CellEditorSetValueEventArgs) Handles CellEditorTxtResult.SetControlValue
        If TypeOf e.Control Is TextBox AndAlso vtResults.SelectedRow IsNot Nothing AndAlso vtResults.SelectedRow.Level = 2 Then

            Dim txtCtrl As TextBox = DirectCast(e.Control, TextBox)
            With txtCtrl
                .Name = "txtResult"
                .AutoCompleteMode = AutoCompleteMode.SuggestAppend
                .AutoCompleteSource = AutoCompleteSource.CustomSource
                .AutoCompleteCustomSource.Add("aaa")
                .AutoCompleteCustomSource.Add("bbb")
                .AutoCompleteCustomSource.Add("12345")
            End With

        End If
    End Sub


The textbox shows up upon editing and text values can be entered and edited but the autocomplete feature is not working.
[/code]

AutoComplete does not appear to work for TextBoxes if multiline is set to true. Virtual Tree sets multiline true by default. If you change that it should work. Your SetControlValue handler should also set the txtCtrl.Text text value of the control eg

Code:
txtCtrl.Text = e.Value.ToString()


Otherwise when you edit a cell the edit control will not be initialized with the existing value of the cell.
