How to pass the checkbox list value from one page to another

 I have a checkboxlist ,which has its databound from SQL dabase.I am using this checkboxlist in administrator page.So that when a checkbox in the checkboxlist is clicked I would like to pass this value to another page in which I enable a function(For example I enable a Button if the checkboxlist is checked else the button is disabled).
  I tried to pass this value(the checkboxlist selected value) using a session but I dont know how to do this exactly as I am new to and C#.
 I am trying with the code below .Can you help me how I can achieve this

The code in the Administrator page
code in aspx.cs 

 protected void Page_Load(object sender, EventArgs e)
                if (Session["Sel_Inst"] != null)
                    Label2.Text = Session["Sel_Inst"].ToString();

 protected void CheckBoxList1_SelectedIndexChanged(object sender, EventArgs e)
            Label1.Text = string.Empty;
            foreach (ListItem listitem in CheckBoxList1.Items) { 
                if (listitem.Selected) 
                    Label1.Text += listitem.Value + "<br />";
            Session["Sel_Inst"] = Convert.ToString(Label1.Text);

code in aspx 

            ID="CheckBoxList1" runat="server" AutoPostBack="True" DataSourceID="SqlDataSource2" 
            DataTextField="Institution_name" DataValueField="Institution_no" 
            onselectedindexchanged="CheckBoxList1_SelectedIndexChanged" >

Hmm.  I think your best approach would be to commit the data back to the SQL database, then use the committed values to dis/enable the buttons on the second page.

If you don't want to do that, you can store the checkbox values (both checked and unchecked) in an array, stuff that into your session variable, then parse the array on the second page to dis/enable the buttons.

you can use a hiddenfield and with Postbackurl feature with PreviousPage, or you can also use querystring
