gridView基本操作

用gricView实现常用的操作 选择啊 编辑啊 之类的

注意数据访问是用的EntityFrameWork

为了方便 页面代码这里我就不贴了，免得占地方

public partial class _Default : System.Web.UI.Page 
{
    protected void Page_Load(object sender, EventArgs e)
    {
        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();
    }
}

最终效果：
