DataList嵌套DataGrid实现折叠展开效果

效果如图:

 

关键代码:

  protected void Page_Load(object sender, EventArgs e)
    {

        if (!IsPostBack)
        {
            BindDataList();
            modify();
        }
    }
    protected void modify()
    {
        for (int i = 0; i < DataList1.Items.Count;)
        {
            DataGrid dg1 = (DataGrid)DataList1.Items
