本文介绍了一个关于 DataGridView 中 ComboBox 控件编程的示例，展示了如何为特定列的 ComboBox 添加事件处理器，以便在选择更改时触发特定操作。

   Private Sub Grid_EditingControlShowing(ByVal sender As Object, ByVal e As System.Windows.Forms.DataGridViewEditingControlShowingEventArgs) Handles Grid.EditingControlShowing
        If Grid.CurrentCell.ColumnIndex = COL_HINCD Then
            If Not (TypeOf (e.Control) Is ComboBox) Then Exit Sub
            Dim cbo As ComboBox
            cbo = TryCast(e.Control, ComboBox)
            If cbo IsNot Nothing Then
                RemoveHandler cbo.SelectedIndexChanged, AddressOf ComboBox_SelectedIndexChanged
                AddHandler cbo.SelectedIndexChanged, AddressOf ComboBox_SelectedIndexChanged
            End If
        End If
    End Sub
