数据过滤器干扰UltraGrid内部UltraCombo上的自动完成

我在UltraGrid中设置了一个UltraCombo,AutoComplete设置为“建议”。UltraCombo具有“Name”的DisplayMember和“ID”的ValueMember。我发现,当我将DataFilter附加到UltraCombo时(我想在值为零时使其显示为空),如果他们键入的数字恰好与ID匹配,并且还以Name开头,它将自动完成,但底层值从未更改。因此,不会触发AfterUpdate或CellChange,当您离开单元格时,它将变为空白。如何让“自动完成”工作,但仍将零值显示为空白?以下是我的代码(注意,如果您注释掉设置UltraCombo1.DataFilter的行,更新可以正常工作,但您会丢失DataFiltering):

Imports Infragistics.Win.UltraWinGrid
Imports Infragistics.Win

Public Class Form1

    Public Sub New()
        InitializeComponent()
        Dim datatableCombo = New DataTable
        datatableCombo.Columns.Add("ID", GetType(Integer))
        datatableCombo.Columns.Add("Name", GetType(String))
        datatableCombo.Rows.Add({1, "123"})
        datatableCombo.Rows.Add({2, "234"})
        datatableCombo.Rows.Add({3, "456"})

        UltraCombo1.DataFilter = New MyDataFilter()
        UltraCombo1.DataSource = datatableCombo
        UltraCombo1.ValueMember = "ID"
        UltraCombo1.DisplayMember = "Name"

        Dim position As Integer = 0
        UltraCombo1.DisplayLayout.Bands(0).Columns("ID").Hidden = False
        UltraCombo1.DisplayLayout.Bands(0).Columns("ID").Header.VisiblePosition = position
        position += 1
        UltraCombo1.DisplayLayout.Bands(0).Columns("Name").Hidden = False
        UltraCombo1.DisplayLayout.Bands(0).Columns("Name").Header.VisiblePosition = position
        position += 1

        Dim datatableGrid = New DataTable
        datatableGrid.Columns.Add("ID", GetType(Integer))
        datatableGrid.Columns.Add("Name", GetType(String))
        UltraGrid1.DataSource = datatableGrid

        UltraGrid1.DisplayLayout.GroupByBox.Hidden = True
        UltraGrid1.DisplayLayout.Override.RowSelectors = DefaultableBoolean.True
        UltraGrid1.DisplayLayout.Override.AllowAddNew = AllowAddNew.TemplateOnBottom

        UltraGrid1.DisplayLayout.Bands(0).Columns("ID").EditorComponent = UltraCombo1
        UltraGrid1.DisplayLayout.Bands(0).Columns("ID").CellClickAction = CellClickAction.EditAndSelectText
        UltraGrid1.DisplayLayout.Bands(0).Columns("ID").Style = ColumnStyle.DropDownValidate
    End Sub

    Public Class MyDataFilter
        Implements Infragistics.Win.IEditorDataFilter

        Public Function Convert(ByVal convertArgs As Infragistics.Win.EditorDataFilterConvertArgs) As Object Implements Infragistics.Win.IEditorDataFilter.Convert
            ' Shouldn't affect anything?
            convertArgs.Handled = False
            Return Nothing
        End Function
    End Class

End Class
