C# code

//在datagridview的Editing事件里面写privatevoid dataGridView_EditingControlShowing(object sender, DataGridViewEditingControlShowingEventArgs e)
{
    ComboBox cb = e.Control as ComboBox;
    if (cb !=null)
    {
        cb.SelectedIndexChanged +=new EventHandler(cb_SelectedIndexChanged);
    }
}
void cb_SelectedIndexChanged(object sender, EventArgs e)
{
     //这里执行你需要的,这就是下拉事件}
