Bind a multi-dimensional ArrayList to a Gridview - asp.net

Question

I have a DataGrid of seats available, each with a checkbox to be able to reserve the seat. In the button click event, if the CheckBox is clicked, I am adding the contents of the row to an ArrayList, then adding the ArrayList to a session before redirecting to the confirmation page:
protected void Reserve_Click(object sender, EventArgs e)
{
{
ArrayList seatingArreaList = new ArrayList();
for (int i = 0; i < GridView1.Rows.Count; i++)
{
Guid SeatId = (Guid)GridView1.DataKeys[i][0];
CheckBox cbReserve = (CheckBox)GridView1.Rows[i].FindControl("cbReserve");
Label lblSection = (Label)GridView1.Rows[i].FindControl("lblSection");
Label lblRow = (Label)GridView1.Rows[i].FindControl("lblRow");
Label lblPrice = (Label)GridView1.Rows[i].FindControl("lblPrice");
if (cbReserve.Checked)
{
string tempRowInfo = lblSection.Text + "|" + lblRow.Text + "|" + lblPrice.Text;
seatingArreaList.Add(tempRowInfo);
}
}
// Add the selected seats to a session
Session["Seating"] = seatingArreaList;
}
Response.Redirect("Confirm.aspx?concertId=" + Request.QueryString["concertId"]);
}
On the confirmation page, Id like to split this array up and bind it to another gridview in their individual columns.
On the confirmation page, a session exists that has three columns separated with a pipe, I am struggling to split this up and bind it to a confirmation grid.
Please help!

Answer 1

This would probably be easier to just create a DataTable, then add it to the session variable. Once redirected to the confirmation page just bind GridView to the DataTable pulled from the session variable.
protected void Reserve_Click(object sender, EventArgs e)
{
DataTable dt = new DataTable();
dt.Columns.Add("Section");
dt.Columns.Add("Row");
dt.Columns.Add("Price");
{
ArrayList seatingArreaList = new ArrayList();
for (int i = 0; i < GridView1.Rows.Count; i++)
{
Guid SeatId = (Guid)GridView1.DataKeys[i][0];
CheckBox cbReserve = (CheckBox)GridView1.Rows[i].FindControl("cbReserve");
Label lblSection = (Label)GridView1.Rows[i].FindControl("lblSection");
Label lblRow = (Label)GridView1.Rows[i].FindControl("lblRow");
Label lblPrice = (Label)GridView1.Rows[i].FindControl("lblPrice");
if (cbReserve.Checked)
{
DataRow dr = dt.NewRow();
dr["Section"] = lblSection.Text;
dr["Row"] = lblRow.Text;
dr["Price"] = lblPrice.Text;
dt.Rows.Add(dr);
}
}
// Add the selected seats to a session
Session["Seating"] = dt;
}
Response.Redirect("Confirm.aspx?concertId=" + Request.QueryString["concertId"]);
}

Answer 2

var q = from dto in seatingArreaList
let z = dto.Split("|".ToCharArray())
select z;
and then just bing q to the grid.
