我有一个带有 datagridviewcomboboxcolumn 的 datagridview，我在该列上启用了编辑。只要没有为该列设置 datapropertyname，它就可以工作。

当设置了 datapropertyname 并且我在组合框中键入该项目时，它应该被建议，但是当按下 ENTER 时，之前选择的项目再次被选中。

当按下回车后未设置数据属性名时，建议的项目被选中。

我启用编辑的代码：

Private Sub DataGridView1_EditingControlShowing(ByVal sender As Object, ByVal e As DataGridViewEditingControlShowingEventArgs) Handles DataGridView1.EditingControlShowing
    If e.Control.GetType Is GetType(DataGridViewComboBoxEditingControl) Then
        Dim cb As ComboBox = TryCast(e.Control, ComboBox)
        If cb IsNot Nothing Then
            cb.DropDownStyle = ComboBoxStyle.DropDown
        End If
    End If
End Sub
