DotNetBar SuperDataGrid中的ComboBox渲染

Question

我希望将DotNetBar SuperDataGrid控件中的列呈现为comboBox (更准确地说，是GridComboBoxExEditControl)。SuperDataGrid连接到绑定源。在DataBindingComplete事件中，我有以下内容：

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

MyComboBox类是这样的：

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

这将导致以下结果: SuperDataGrid在单元格中显示正确的值。绑定是正确的，如果将"ArticleID“呈现为”文章“，则每个值都是正确的。问题是，当值从ArticleID = 1 to ArticleID = 2 (No1=“文章No2")转移到SuperDataGrid = "Artcle No2”时，SuperDataGrid会进入某种形式的无限循环，并且值开始在1和2之间移动。如果有人能在这个问题上提供一些建议，我将不胜感激。附言:我还试过这个：

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"

得到了同样的结果。

Answer 1

{ArticleBindingSource，“文章”，"ArticleID"}当DisplayMember，ValueMember的值相同时，我认为这是错误的
