The code for the switch works but when I run the last one the problem get
stuck. Here is the code for submit button:

protected void btnSubmit_Click1(object sender, EventArgs e)
{
// Session cookie to be carried over to Conformation.aspx
lblClassification.Text = DropDownList1.SelectedItem.ToString();
Session["Classification"] = lblClassification.Text;

if (DropDownList2.SelectedIndex == 1)
{
Session["choice"] = DropDownList2.SelectedItem.Value;
lblPage.Text = Convert.ToString(DropDownList2.SelectedIndex == 1);
Session["nPage"] = lblPage.Text;

Response.Redirect("Network.aspx");
}
else if (DropDownList2.SelectedIndex == 2)
{
Session["choice"] = DropDownList2.SelectedItem.Value;
lblPage.Text = Convert.ToString(DropDownList2.SelectedIndex == 2);
Session["sPage"] = lblPage.Text;

Response.Redirect("Server.aspx");
}
else if (DropDownList2.SelectedIndex == 3)
{
Session["choice"] = DropDownList2.SelectedItem.Value;
lblPage.Text = Convert.ToString(DropDownList2.SelectedIndex == 3);
Session["sdPage"] = lblPage.Text;

Response.Redirect("Storage.aspx");
}
else if (DropDownList2.SelectedIndex == 4)
{
DropDownList2.Enabled = false;
Session["choice"] = DropDownList2.SelectedItem.Value;
lblPage.Text = Convert.ToString(DropDownList2.SelectedIndex == 4);
Session["wsPage"] = lblPage.Text;

Response.Redirect("Workstation.aspx");
}
else
Session.Clear();
}

And here is the code for the switch:

public void MainSessionData()
{
string choice = (string)Session["choice"];

switch (choice)

lblWS.Text = "S".ToLower();
if (Session["Classification"].Equals("Top Secret"))
lblWS.Text = "TS".ToLower();
}
// If user choose none of the above program defaults to

if (Session["Classification"] != null)
{
lblwsClass.Text =
Session["Classification"].ToString();
}
lblWorkstation.Text = Session["wsPage"].ToString();
UpdatePanel4.Visible = true;
wsPassSessionData();
UpdatePanel1.Visible = false;
UpdatePanel2.Visible = false;
UpdatePanel3.Visible = false;
}
break;

The program hang if I try to do some after I choose "Workstaion"

I think first of all you should try to make the code more clear. You
have so many vain lines and it is not easy to see the core.

For example,

#1 if (DropDownList2.SelectedIndex == 1)
#2 {
#3 Session["choice"] = DropDownList2.SelectedItem.Value;
#4 lblPage.Text = Convert.ToString
(DropDownList2.SelectedIndex == 1);
#5 Session["nPage"] = lblPage.Text;
#6 Response.Redirect("Network.aspx");
#7 }

1) Lines #1 and #4 do the same.
2) Line #4 assigns always "true" in all cases except the "else" case.
3) Line #2 does the same in all cases
4) Not sure why you need to have different session key for each case
but it looks like #5 does the same in all cases too

So, finally you can at least have something like this

// Session cookie to be carried over to Conformation.aspx
lblClassification.Text = DropDownList1.SelectedItem.ToString();
Session["Classification"] = lblClassification.Text;
lblPage.Text = "true";
Session["choice"] = DropDownList2.SelectedItem.Value;
if (DropDownList2.SelectedIndex == 1)
{
Session["nPage"] = lblPage.Text;
Response.Redirect("Network.aspx");
}
else if (DropDownList2.SelectedIndex == 2)
{
Session["sPage"] = lblPage.Text;
Response.Redirect("Server.aspx");
}
else if (DropDownList2.SelectedIndex == 3)
{
Session["sdPage"] = lblPage.Text;
Response.Redirect("Storage.aspx");
}
else if (DropDownList2.SelectedIndex == 4)
{
DropDownList2.Enabled = false;
Session["wsPage"] = lblPage.Text;
Response.Redirect("Workstation.aspx");
}
else
Session.Clear();

Do the same with you second method and I am sure you will easily find
the problem.

You last case calls wsPassSessionData(); check if that method is ok

I can't find anything wrong with that method, I found out if the user
chooses Workstation first then goes back to the home page and chooses
anything else, the program hang at Response.Redirect("ProcessName.aspx");

it probably means that ProcessName.aspx is incorrect.
