Hi,
I did what you wrote. But still not working (display Session not found). Here is my code. Please correct my code if I wrong. Thanks in advance.
private void Page_Init(object sender, System.EventArgs e)
{
string str = (Request.QueryString["ds"]!=null) ? Request.QueryString.Get("ds").ToString():"";
if (Session[str] == null)                    
{
Response.Write("Session not found.");
return;
}
DataSet ds = (DataSet)Session[str];
rd.FileName = Server.MapPath(ReportFileName);
crv.ReportSource = rd;
rd.SetDataSource(ds);
crv.DataBind();
}
