ช่วยหน่อยค่ะ ต้องการส่งค่าไปแสดงอีกหน้านึงค่ะ ช่วยดูหน่อยค่ะว่าเขียนถูกไหม asp.net c# |

ทำแล้วค่ะ แต่ของดิฉันก็ยังไม่ได้ก็เลยลองเปลี่ยนมาทำ แบบนี้
หน้า Default.aspx
<asp:GridView ID="GridView1" runat="server" onrowcommand="GridView1_RowCommand">
<Columns>
<asp:ButtonField CommandName="see1" HeaderText="ลำดับ" DataTextField="id" />
<asp:ButtonField CommandName="see1" HeaderText="ชื่อ" DataTextField="name" />
</Columns>
หน้า Default.aspx.cs
rotected void Page_Load(object sender, EventArgs e)
{
string StrConn = WebConfigurationManager.ConnectionStrings["DD"].ToString();
SqlConnection Conn = new SqlConnection(StrConn);
Conn.Open();
string sqlProduct;
sqlProduct = " SELECT * FROM student WHERE id ='" + TextBox1.Text + "' ";
SqlDataAdapter da = new SqlDataAdapter(sqlProduct, Conn);
DataSet ds = new DataSet();
da.Fill(ds, "student");
GridView1.DataSource = ds.Tables["student"];
GridView1.DataBind();
}
protected void GridView1_RowCommand(object sender, GridViewCommandEventArgs e)
{
int rowIndex1 = Convert.ToInt32(e.CommandArgument);
if (e.CommandName == "see1")
{
String id1_1 = GridView1.Rows[rowIndex1].Cells[0].Text;
Session["sent1"] = id1_1;
String id1_2 = GridView1.Rows[rowIndex1].Cells[1].Text;
Session["sent2"] = id1_2;
Response.Redirect("Default2.aspx");
}
}
ค่ะ แต่หน้าที่รับข้อมูลก็ไม่แสดงค่า ไม่รู้ว่าเขียนอะไรผิด
หน้า Default2.aspx.cs
Label1.Text = Session["sent1"].ToString();
Label2.Text = Session["sent2"].ToString();
ช่วยหน่อยนะคะ ลองทำหลายวิธีค่าก็ไม่ยอมไปแสดงหน้าDefault2.aspx ซักที

Code (C#)
//*** Hyperlink ***//
Label hplEdit = (HyperLink)(e.Row.FindControl("hplEdit"));
if (hplEdit != null)
{
hplEdit.Text = "Edit";
hplEdit.NavigateUrl = "WebPage.aspx?CustomerID=" + (string)DataBinder.Eval(e.Row.DataItem, "CustomerID");
