如何通過會話將值從gridview傳遞到另一個頁面？

Question

我想通過會話的幫助按下按鈕時，從網格視圖傳遞一個值到另一個頁面。如何實現它？

C＃代碼：

保護無效的Page_Load（對象發件人，EventArgs的）

{ 
     if (!IsPostBack) 
     { 
      BindEmployeeDetails(); 
     } 
    } 
    protected void BindEmployeeDetails() 
    { 
     con.Open(); 
     SqlCommand cmd = new SqlCommand("Select uniqueref,fldCustomerName,fldCustomerAddress,fldCustomerCity,fldOrderValue,fldINRrEUR from asm", con); 
     SqlDataAdapter da = new SqlDataAdapter(cmd); 
     DataSet ds = new DataSet(); 
     da.Fill(ds); 
     con.Close(); 
     if (ds.Tables[0].Rows.Count > 0) 
     { 
      GridView1.DataSource = ds; 
      GridView1.DataBind(); 
     } 
     else 
     { 
      ds.Tables[0].Rows.Add(ds.Tables[0].NewRow()); 
      GridView1.DataSource = ds; 
      GridView1.DataBind(); 
      int columncount = GridView1.Rows[0].Cells.Count; 
      GridView1.Rows[0].Cells.Clear(); 
      GridView1.Rows[0].Cells.Add(new TableCell()); 
      GridView1.Rows[0].Cells[0].ColumnSpan = columncount; 
      GridView1.Rows[0].Cells[0].Text = "No Records Found"; 
     } 

    } 



    protected void Add_Click(object sender, EventArgs e) 
    { 
     Response.Redirect("add.aspx"); 
    } 

    protected void Edit_Click(object sender, EventArgs e) 
    { 

     Response.Redirect("edit.aspx"); 
    } 

Answer 1

設定值成Session，是這樣的：從Session

// We will say that `GridView1.PrimaryKey` is an int 
Session["YourGridValue"] = GridView1.Value; 

讀取值，這樣：

// Check first to make sure our value is in Session 
    if(null != Session["YourGridValue"]) 
    { 
     int sessionValue = (int)Session["YourGridValue"]; 
    } 

注意：Session中的值存儲爲Object，但可以是字符串，int，List等。因此在檢索值時必須將其轉換爲正確的類型。
