I have a login.aspx that user uses to login. It calls dologin.aspx which connects to the database, verifies the user information then sets the session variables. After setting the session variables it redirects to default.aspx which has 3 frames, header, menu and Report. When pipeline.aspx page loads in the report frame, all my session variables are gone. I try to Response.Write(Session["arType"]); and I get nothing. Below is the code for <B>DoLogin.aspx</B>

if (lobj_dataset.Tables[0].Rows.Count >0) {
     Session["UserID"]=lobj_dataset.Tables[0].Rows[0]["ID"];
     Session["Username"]=lobj_dataset.Tables[0].Rows[0]["Username"];
  Session["FullName"]=Convert.ToString(lobj_dataset.Tables[0].Rows[0]["FullName"]).Trim();
     Session["ARView"]=lobj_dataset.Tables[0].Rows[0]["ARView"];
     Session["Mapping"]=lobj_dataset.Tables[0].Rows[0]["Mapping"];
 Session["MenuUpdates"]=lobj_dataset.Tables[0].Rows[0]["MenuUpdates"];  Session["RootLevel"]=Convert.ToInt32(lobj_dataset.Tables[0].Rows[0]["RootLevel"]); 
 Session["AccountManager"]=lobj_dataset.Tables[0].Rows[0]["AccountManager"];
     Session["gridType"]=0;     Session["arType"]="%";
     Session["sortType"]="Priority, Company";     Session.Timeout=60;
     Response.Redirect("default.aspx", false); 
}
 else {
     Response.Redirect("login.aspx"); 
} 
lobj_connection.Close();

Any suggestions would be greatly appreciated, I've been stuck on this all day and need to move on as quick as possible.

Thanks,
Josh

I can't see anything wrong with the code above, the problem could be somewhere else.

First of all, make sure you have session cookies enabled in your browser. Try making a new project with 2 pages and set a single session variable on one page and test it on the other:

Page 1, just one button. In the OnClick event:
Session["test"] = "Foo";
Response.Redirect("page2.aspx");

Page 2, just a label. In the OnLoad event:
Label1.Text = (string)Session["test"];

and see if Page 2 displays Foo. If it doesn't, you most likely have a problem with the way sessions are set up, and not the code.

p.s. You don't need 2 pages to do a login. Login.aspx can have 2 textboxes and a button, and the login code can be put in the buttons OnClick event.
Also, your code will be cleaner if you set up a new object to hold the user details and just set a single session variable to hold that object:

public struct TUser
{
    public int UserID
    public string Username;
    public string FullName;
    public string ARView;
   // ...etc
}

TUser MyUser = new TUser()
MyUser.Username = "Foo";
MyUser.FullName = "Foo Bar";
MyUser.ID = "42";
Session["CurrentUser"] = MyUser;

Label1.Text = "Welcome to our site, " + ((TUser)Session["CurrentUser"]).FullName;
