ComboBox在DotNetBar SuperDataGrid中渲染

我想在DotNetBar SuperDataGrid Controll中將列渲染爲組合框（更精確地作爲GridComboBoxExEditControl）。 SuperDataGrid連接到綁定源。在DataBindingComplete事件我有以下幾點：ComboBox在DotNetBar SuperDataGrid中渲染

Private Sub SuperGrid_DataBindingComplete(ByVal sender As Object, ByVal e As DevComponents.DotNetBar.SuperGrid.GridDataBindingCompleteEventArgs) Handles SuperGrid.DataBindingComplete 
    Dim panel As DevComponents.DotNetBar.SuperGrid.GridPanel 
    panel = e.GridPanel 

    panel.Columns("ArticleID").RenderType = GetType(MyComboBox) 
    panel.Columns("ArticleID").RenderParams = New Object() {ArticleBindingSource, "Article", "Article"} 

End Sub

而且MyComboBox類雲：

Public Class MyComboBox 
Inherits GridComboBoxExEditControl 
Public Sub New(ByVal Bind As BindingSource, ByVal disp As String, ByVal val As String) 
    DataSource = Bind 
    DisplayMember = disp 
    ValueMember = val 
End Sub 
End Class

這將導致以下：的SuperDataGrid顯示在單元格中正確的價值觀。如果作爲「Article」呈現，綁定是正確的，並且「ArticleID」的每個值都是正確的。問題是，當數值從ArticleID = 1 to ArticleID = 2 （Article =「Article No1」到Article =「Artcle No2」）變化時，SuperDataGrid進入某種形式的無限循環，並且值開始在1和2之間切換。錯誤？如果有人能提供一些關於這個問題的建議，我將非常感激。 P.S. 我也試過這個：

panel.Columns("ArticleID").EditorType = GetType(GridComboBoxExEditControl) 
Dim art As GridComboBoxExEditControl = DirectCast(panel.Columns("ArticleID").EditControl, GridComboBoxExEditControl) 
     art.DataSource = ArticleBindingSource 
     art.DisplayMember = "Article" 
art.ValueMember = "ArticleID"

得到了同樣的結果。

{ArticleBindingSource，「Article」，「ArticleID」}我認爲當DisplayMember的值相同時， ValueMember
