2、后台关键代码
Session
public partial class 展示 : System.Web.UI.Page {
public string imgUrl1; public string Name1; public string Price1; public string Number1;
protected void Page_Load(object sender, EventArgs e) { }
protected void Button1_Click(object sender, EventArgs e)
{
session1();
Response.Write(\购物车.aspx','_blank')\); // Response.Redirect(\购物车.aspx\ }
protected void Button2_Click(object sender, EventArgs e) {
session1(); }
protected void Button4_Click(object sender, EventArgs e) {
int n = Convert.ToInt32(num.Text); n++;
string s = Convert.ToString(n); num.Text = s; }
protected void Button3_Click(object sender, EventArgs e) {
int n = Convert.ToInt32(num.Text); n--;
string s = Convert.ToString(n); num.Text = s; }
public void session1() {
imgUrl1 = \商品1.jpg\; Name1 = \商品1\; Price1 = Label3.Text; Number1 = num.Text; Session[\] = imgUrl1; Session[\] = Name1; Session[\] = Price1; Session[\] = Number1; } } 购物车
protected void Button1_Click(object sender, EventArgs e) {
pr1 = Session[\].ToString(); pr2 = Session[\].ToString(); p1 = Convert.ToDouble(pr1); p2 = Convert.ToDouble(pr2); num1 = Session[\].ToString(); num2 = Session[\].ToString();
n1 = Convert.ToInt32(num1); n2 = Convert.ToInt32(num2); total = p1 * n1 + p2 * n2;
Label1.Text = Convert.ToString(total); }
3、测试结果
六、查询页面 1、前台关键代码
2.后台关键代码
protected void Page_Load(object sender, EventArgs e) { }
protected void DropDownList1_SelectedIndexChanged(object sender, EventArgs e) {
String value = DropDownList1.SelectedItem.Text; //Console.WriteLine(value); Label1.Text = value;
OleDbConnection conn = new OleDbConnection(\Source=\ + Server.MapPath(\)); //建立Command对象
OleDbCommand cmd = new OleDbCommand(\ + value + \, conn);
//建立DataAdapter对象
OleDbDataAdapter adp = new OleDbDataAdapter(cmd);
//AccessDataSource2.SelectCommand=\ //GridView1.DataSource = //建立DataSet对象
DataSet ds = new DataSet(); //填充DataSet对象 adp.Fill(ds, \); //绑定数据对象
GridView1.DataSource = ds.Tables[\].DefaultView; GridView1.DataBind(); }
protected void Button1_Click(object sender, EventArgs e) {
String value = DropDownList1.SelectedItem.Text;
OleDbConnection conn = new OleDbConnection(\Source=\ + Server.MapPath(\)); //建立Command对象
OleDbCommand cmd = new OleDbCommand(\ + value + \, conn);
//建立DataAdapter对象
OleDbDataAdapter adp = new OleDbDataAdapter(cmd);
//AccessDataSource2.SelectCommand=\ //GridView1.DataSource = //建立DataSet对象
DataSet ds = new DataSet(); //填充DataSet对象 adp.Fill(ds, \); //绑定数据对象
GridView2.DataSource = ds.Tables[\].DefaultView; GridView2.DataBind();
