后台cs文件：

复制代码代码如下:

 
protected void Page_Load(object sender, EventArgs e) 
{ 
if (!IsPostBack) 
{ 
load(); 
} 
} 
private void load()//就实现绑定 
{

Jquery三层实现删除功能.BLL.T_News bb = new BLL.T_News(); 
string sqlwhere = "Id<25"; 
ds = bb.GetList(sqlwhere);//获取dataset绑定 
this.GridView1.DataSource = ds; 
GridView1.DataBind(); 
} 
protected void Button1_Click(object sender, EventArgs e) 
{ 
//遍历每一行 
foreach (GridViewRow item in GridView1.Rows)//一定要记住这里是gridviewrow不是datarow 
{ 
CheckBox cb = (CheckBox)item.FindControl("CheckBox3");//找到这个选中项 
if (cb.Checked)//选中 
{

if (bb.DeleteList(item.Cells[1].Text))//调用bb.DeleteList(id）删除 
{ 
Response.Write("删除成功"); 
} 
load();
