protected void GridView1_RowDeleting(object sender, GridViewDeleteEventArgs e)

 //获取ID的值
        string strId = this.GridView1.Rows[e.RowIndex].Cells[1].Text.Trim();
 //获取LinkButton1的控件
        LinkButton lb = (LinkButton)GridView1.Rows[e.RowIndex].FindControl("LinkButton1");
        Label17.Text = lb.Text.ToString();
        contion += " and product.babyClassId = " + strId;
        Bind_DataList(contion, 3);
