        if (!IsPostBack)

        {

            if (Session["valiCode"] != null)

                Response.Write(Session["valiCode"]);



            GridView1.DataSource = new BslDB().departInfo;

            GridView1.DataBind();

        }

    }

    protected void Button1_Click(object sender, EventArgs e)

    {

        //MembershipUser user= Membership.GetUser();

        ////User.Identity.Name = "xx";

        //string name = User.Identity.Name;

        //Response.Write(user.UserName);

        BslDB bsl = new BslDB();

        departInfo depart = new departInfo();

        depart.departName = depName.Text;

        depart.telphone = phone.Text;

        depart.leader = person.Text;



        bsl.AddTodepartInfo(depart);



        int result = bsl.SaveChanges();





        GridView1.DataSource = bsl.departInfo;

        GridView1.DataBind();

        

    }







   

    protected void GridView1_SelectedIndexChanging1(object sender, GridViewSelectEventArgs e)

    {

        ////GridView1.Rows[e.NewSelectedIndex].dataf

        //GridView1.DataKeys[e.NewSelectedIndex].Value;

        if(e.NewSelectedIndex!=-1)

        Response.Write("xxx" + GridView1.DataKeys[e.NewSelectedIndex].Value);

        int id = Convert.ToInt32( GridView1.DataKeys[e.NewSelectedIndex].Value);

        var de = new BslDB().departInfo.Where(c => c.id ==id ).First() ;

        depName.Text = de.departName;

        phone.Text = de.telphone;

        person.Text = de.leader;

        ViewState["curDep"] = id.ToString();

        Response.Write(de.departName);

        

    }

    protected void Button2_Click(object sender, EventArgs e)

    {

        BslDB db=new BslDB();

        var de = db.departInfo.Where(c => c.id == 8).First();

        de.departName = "yy俱乐部";

        db.SaveChanges();

    }

}
