后臺cs文件：

復(fù)制代碼代碼如下:

 
protected void Page_Load(object sender, EventArgs e) 
{ 
if (!IsPostBack) 
{ 
load(); 
} 
} 
private void load()//就實(shí)現(xiàn)綁定 
{ 
Jquery三層實(shí)現(xiàn)刪除功能.Model.T_News mm = new Model.T_News(); 
Jquery三層實(shí)現(xiàn)刪除功能.BLL.T_News bb = new BLL.T_News(); 
string sqlwhere = "Id<25"; 
ds = bb.GetList(sqlwhere);//獲取dataset綁定 
this.GridView1.DataSource = ds; 
GridView1.DataBind(); 
} 
protected void Button1_Click(object sender, EventArgs e) 
{ 
//遍歷每一行 
foreach (GridViewRow item in GridView1.Rows)//一定要記住這里是gridviewrow不是datarow 
{ 
CheckBox cb = (CheckBox)item.FindControl("CheckBox3");//找到這個(gè)選中項(xiàng) 
if (cb.Checked)//選中 
{ 
Jquery三層實(shí)現(xiàn)刪除功能.BLL.T_News bb = new BLL.T_News(); 
if (bb.DeleteList(item.Cells[1].Text))//調(diào)用bb.DeleteList(id）刪除 
{ 
Response.Write("刪除成功"); 
} 
load();
