Question

为什么gridview 绑定的东西都不显示？？高手帮帮忙啊，解决了会再加分！

protected void GridView1_RowCommand(object sender, GridViewCommandEventArgs e)
{
DataTable cart1 = new DataTable();
if (e.CommandName == "select")
{
if (Session["shopcart2"] == null)
{
cart1.Columns.Add("商品编号", typeof(string));
cart1.Columns.Add("商品名称", typeof(string));
cart1.Columns.Add("单价", typeof(double));
cart1.Columns.Add("订购数量", typeof(int));
cart1.Columns.Add("合计", typeof(double));
Session["shopcart2"] = cart1;

}
// Response.Write("<script>alert('购物车中没有任何商品!') </script>");

cart1 = (DataTable)Session["shopcart2"];
int index = Convert.ToInt32(e.CommandArgument);
GridViewRow row = GridView1.Rows[index];
//Session[Session.SessionID+"uid"] = Label1.Text;
//System.Web.UI.WebControls.GridViewRow rows = (GridViewRow)((Control)sender).Parent.Parent;
TextBox tt = ((System.Web.UI.WebControls.TextBox)row.Cells[1].FindControl("TextBox1"));
string spl = tt.Text;
int sl = int.Parse(spl);
string bh = row.Cells[2].Text;
string name = row.Cells[3].Text;
string sdj = row.Cells[4].Text;
double dj = double.Parse(sdj);
DataRow rr = cart1.NewRow();
rr["商品编号"] = bh;
rr["商品名称"] = name;
rr["单价"] = dj;
rr["订购数量"] = sl;
double zj = dj * sl;
rr["合计"] = zj;
cart1.Rows.Add(rr);
Session["shopcart2"] = cart1;
}
}
gridview的数据源时session["shopcart2"]，pageload也有databind，可是进到这一页什么都不显示？？？！！
