User Page Authentication Using Sessions

I am trying to prevent unauthorized access to pages on my VB.Net website. I have set up users manually and I am using Sessions to store the information about the User. I am not using the built in login and authentication features due to other reasons.

The code I am trying to run on Page Load is ..
 
Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
        If Session("Role") = "Admin" Then

        Else
            Response.Redirect("Default.aspx")
        End If
    End Sub

Open in new window


So if the Session("Role") is "Admin" then it will do nothing and allow the user access to the page, but for all other users it will send them back to the homepage.

This however doesnt work, you always get sent back to the default.aspx page, regardless of whether Session("Role") = Admin or not, as I have checked by using a MsgBox(Session("Role")), which returns "Admin".

Im thinking im using the wrong event, should I use something instead of Load?

Cheers,

Chris

example for adding column:-

   
    DataGridViewColumn col = new DataGridViewColumn();
	DataGridViewCell cell = new DataGridViewTextBoxCell();
	col.CellTemplate = cell;
	col.HeaderText = "testing";
	col.Name = "testing";
	col.Visible = true;
	col.Width = 60;

Please create the Session("Role")  in the login page or where ever required then only check it because the sessions are not created automatically.

I realised that the problem was the Session was being created with spaces after the string, which when i was comparing it to "Admin" was causing a problem, So i ran the Session("Role") through a function that removed white spaces and it works fine now.
