if(session["cart"]!=null) {
DataTable da = new DataTable();

DataRow dr = da.NewRow();
dr["ProductName"] = ds.Tables[0].Rows[0]["ProductName"];

da.Rows.Add(dr);
foreach(DataRow row in da.Rows )
{
dt.ImportRow(row);
}
return dt;
}
Here dt comes with an Emptydata..............
Structure of datatable dt is .......
dt.Columns.Add("ProductImages", typeof(string));
dt.Columns.Add("ProductName", typeof(string));
dt.Columns.Add("Price", typeof(double));
