Session Data and DataGrid

[filmar]

Hi people!
I need some help:
can I do something like this:
DataView CartView;
protected void BindGrid(int paging)
{
DataRow d;
DataTable Cart = new DataTable();
Cart.Columns.Add(new DataColumn("Text", typeof(String)));
Cart.Columns.Add(new DataColumn("Date_Input", typeof(String)));
Cart.Columns.Add(new DataColumn("page", typeof(int)));
int page = 1;
int count = 0;

clsDB objDb = new clsDB();
SqlDataReader dr = objDb.getRS("select top 800 * from Notice");
if (dr != null && dr.HasRows)
{
while (dr.Read())
{
if (count == 20)
{
count = 0;
page++;
}
d = Cart.NewRow();
d[0] = dr["Text"].ToString();
d[1] = dr["Date_Input"].ToString();
d[2] = page.ToString();
Cart.Rows.Add(d);
count++;
}
dr.Close();
}
Session["temp"] = Cart;
Cart.Clear();
Cart.Dispose();
if (objDb != null)
{
objDb.Close();
objDb = null;
}
ItemsGrid.VirtualItemCount = 800;
CartView = new DataView((DataTable)Session["Test"]);
CartView.Rowfilter = "page='"+paging.ToString()+"'";
ItemsGrid.DataSource = CartView;
ItemsGrid.DataBind();
}

I mean can I get Data from Session like this method i used?
DataTable has data coz clsDB works nice.
