VB.Net以编程方式在Rows.Add上设置DataGridViewComboBox .ValueMember

Question

我正在尝试以编程方式设置DataGridViewComboBox的值，当我填充网格时，但我一直收到一个关于无法对组合框进行排序的错误 - ＆＃34;具有DataSource集的ComboBox无法排序。使用基础数据模型对数据进行排序。＆＃34;

我不是要对组合框的数据进行排序，我只是在执行Rows.Add函数时尝试设置值成员。

编辑**整个列应包含相同的组合框项，并且不是特定于行的。

Public Sub LoadComboBox()
Dim comboBox = New Dictionary(Of Integer, String)

    Try
        //myStepTable = data ' SQL query to get ID and Step

        For Each row As DataRow In myStepTable.Rows
            comboBox.Add(row.Item("StepID"), row.Item("Step"))
        Next

        'colStep is the defined name of the combobox column
        colStep.DataSource = New BindingSource(comboBox, Nothing)
        colStep.DisplayMember = "Value"
        colStep.ValueMember = "Key"
End Sub

Public Sub LoadGrid()
    LoadComboBox()
    myDataTable = data 'SQL query to get row data

    For Each row As DataRow In myDataTable.Rows
        dgvRecipeSteps.Rows.Add(row.Item("RowID"), row.Item("StepID"))
    Next
End Sub
