怎么给DataGridViewComboBoxColumn添加SelectedValueChanged事件？

[crowkkk]

在网上找了很久，找不到办法，在论坛里看到C#的实现方法如下：

private void dataGridView1_EditingControlShowing(object sender,
    DataGridViewEditingControlShowingEventArgs e)
{
    ((ComboBox)e.Control).SelectedIndexChanged +=
        new EventHandler(ComboBox_SelectedIndexChanged);
}

private void ComboBox_SelectedIndexChanged(object sender, EventArgs e)
{
    //。。。。。。。;
}

本人初学，这是用的委托吗？但VB代码怎么写呢？

自己拿分了，找了一上午没找到，发贴后马上找到了

Dim comboBox1 As ComboBox
    Private Sub DataGridView1_EditingControlShowing(ByVal sender As System.Object, ByVal e As System.Windows.Forms.DataGridViewEditingControlShowingEventArgs) Handles DataGridView1.EditingControlShowing
        If DataGridView1.CurrentCellAddress.X = 0 Then
            comboBox1 = CType(e.Control, ComboBox)
            RemoveHandler comboBox1.SelectedIndexChanged, New EventHandler(AddressOf ComboBox_SelectedIndexChanged)
            AddHandler comboBox1.SelectedIndexChanged, New EventHandler(AddressOf ComboBox_SelectedIndexChanged)
        End If
    End Sub

    Private Sub ComboBox_SelectedIndexChanged(ByVal sender As System.Object, ByVal e As System.EventArgs)
        MsgBox(comboBox1.SelectedValue.ToString)
    End Sub
