retrieving checkbox values in datalist

I have an .aspx page in which I am retrieving categoryid & category name from sql database's category table. Here I am retriving the categoryid value as checkbox value and near by checkbox I am retriving the categoryname for display purpose. What I want is, I have to show what are the categories that I have selected(by checkbox selection) when I am clicking on a button(named as..get items). I am posting the code I am using and attaching the required output.

Code:

<%@ Import Namespace="System.Data" %>
<%@ Import Namespace="System.Data.SQLClient" %>
<HTML>
	<HEAD>
		<TITLE>UserRegistration-User Details</TITLE>
	</HEAD>
	<% ' Program for requesting user details %>
	<meta content="ASP Express 2.1" name="GENERATOR">
	<script language="VB" runat="server">

		Sub Page_Load(Source as Object, E as EventArgs)
			if not Page.IsPostBack then
				BindData
				
			end if
		End Sub
		Sub doit(Source as Object, E as EventArgs)
			
			
			
		
		End Sub
		Sub BindData()
		    ' To show country table values in list box
		    'Name of stored proc...>sp_SelectCountry
			Dim Varvalu as string
			Varvalu="0"
			Dim sqls as string = "sp_Selectcategory"
			'Connection in web.config file
			Dim myConns As SqlConnection = New SqlConnection(ConfigurationSettings.AppSettings("MyDBConnection"))
			Dim Cmds as New SqlCommand(sqls, MyConns)
			Dim objDR as SQLDataReader
			cmds.CommandType=CommandType.StoredProcedure    ' Tells application that it's using a Stored Procedure
			'Dim objDR as SQLDataReader
			MyConns.Open()
			objDR=Cmds.ExecuteReader(system.data.CommandBehavi  or.CloseConnection)
			MyDataList.DataSource = objDR
			MyDataList.DataBind()
	
		End Sub
 
  
	</script>
	<FORM id="Form1" runat="server">
		<asp:datalist id="MyDataList" runat="server" Width="100%" Font-Size="10" GridLines="None" RepeatColumns="2"
			Headerstyle-HorizontalAlign="Center" Headerstyle-Font-Size="14" Headerstyle-Font-Bold="True"
			Headerstyle-Font-Name="Arial" Headerstyle-BackColor="#E0E0E0" Font-Name="Arial" cellspacing="2"
			cellpadding="2">
			<ItemTemplate>
				
				<asp:CheckBox ID="CBN1" Runat="server" Text='<%# DataBinder.Eval(Container.DataItem, "CategoryName") %>' value='<%# DataBinder.Eval(Container.DataItem, "CategoryID") %>'></asp:CheckBox>
				
				<br>
			</ItemTemplate>
		</asp:datalist>
		<asp:Label ID="label1" runat="server" />
		<asp:Button id="button1" Text="Get Items" onclick="doit" runat="server" /></FORM>
</HTML>

-------------------

Stored procedure is

Code:


CREATE PROCEDURE sp_SelectCategory

AS
begin
		  Select Distinct(CategoryName),CategoryID  from Category
End

------------------

Category Table is

Code:

if exists (select * from dbo.sysobjects where id = object_id(N'[dbo].[FK_SubCategory_Category]') and OBJECTPROPERTY(id, N'IsForeignKey') = 1)
ALTER TABLE [dbo].[SubCategory] DROP CONSTRAINT FK_SubCategory_Category
GO

if exists (select * from dbo.sysobjects where id = object_id(N'[dbo].[Category]') and OBJECTPROPERTY(id, N'IsUserTable') = 1)
drop table [dbo].[Category]
GO

CREATE TABLE [dbo].[Category] (
	[CategoryID] [int] NOT NULL ,
	[CategoryName] [nvarchar] (50) COLLATE SQL_Latin1_General_CP1_CI_AS NOT NULL 
) ON [PRIMARY]
GO

-----------------

web.config file is

Code:

<?xml version="1.0" encoding="utf-8" ?>
<configuration>
   <appSettings> 
<add key="MyDBConnection" value="server=localhost;uid=sa; pwd=;database=Bids" />
</appSettings> 
  <system.web>

    <!--  DYNAMIC DEBUG COMPILATION
          Set compilation debug="true" to insert debugging symbols (.pdb information)
          into the compiled page. Because this creates a larger file that executes
          more slowly, you should set this value to true only when debugging and to
          false at all other times. For more information, refer to the documentation about
          debugging ASP.NET files.
    -->
    <compilation defaultLanguage="vb" debug="true" />

    <!--  CUSTOM ERROR MESSAGES
          Set customErrors mode="On" or "RemoteOnly" to enable custom error messages, "Off" to disable. 
          Add <error> tags for each of the errors you want to handle.

          "On" Always display custom (friendly) messages.
          "Off" Always display detailed ASP.NET error information.
          "RemoteOnly" Display custom (friendly) messages only to users not running 
           on the local Web server. This setting is recommended for security purposes, so 
           that you do not display application detail information to remote clients.
    -->
    <customErrors mode="RemoteOnly" />

    <!--  AUTHENTICATION 
          This section sets the authentication policies of the application. Possible modes are "Windows", 
          "Forms", "Passport" and "None"

          "None" No authentication is performed. 
          "Windows" IIS performs authentication (Basic, Digest, or Integrated Windows) according to 
           its settings for the application. Anonymous access must be disabled in IIS. 
          "Forms" You provide a custom form (Web page) for users to enter their credentials, and then 
           you authenticate them in your application. A user credential token is stored in a cookie.
          "Passport" Authentication is performed via a centralized authentication service provided
           by Microsoft that offers a single logon and core profile services for member sites.
    -->
    <authentication mode="Windows" /> 


    <!--  AUTHORIZATION 
          This section sets the authorization policies of the application. You can allow or deny access
          to application resources by user or role. Wildcards: "*" mean everyone, "?" means anonymous 
          (unauthenticated) users.
    -->
    <authorization>
        <allow users="*" /> <!-- Allow all users -->

            <!--  <allow     users="[comma separated list of users]"
                             roles="[comma separated list of roles]"/>
                  <deny      users="[comma separated list of users]"
                             roles="[comma separated list of roles]"/>
            -->
    </authorization>

    <!--  APPLICATION-LEVEL TRACE LOGGING
          Application-level tracing enables trace log output for every page within an application. 
          Set trace enabled="true" to enable application trace logging.  If pageOutput="true", the
          trace information will be displayed at the bottom of each page.  Otherwise, you can view the 
          application trace log by browsing the "trace.axd" page from your web application
          root. 
    -->
    <trace enabled="false" requestLimit="10" pageOutput="false" traceMode="SortByTime" localOnly="true" />


    <!--  SESSION STATE SETTINGS
          By default ASP.NET uses cookies to identify which requests belong to a particular session. 
          If cookies are not available, a session can be tracked by adding a session identifier to the URL. 
          To disable cookies, set sessionState cookieless="true".
    -->
    <sessionState 
            mode="InProc"
            stateConnectionString="tcpip=127.0.0.1:42424"
            sqlConnectionString="data source=127.0.0.1;Trusted_Connection=yes"
            cookieless="false" 
            timeout="20" 
    />

    <!--  GLOBALIZATION
          This section sets the globalization settings of the application. 
    -->
    <globalization requestEncoding="utf-8" responseEncoding="utf-8" />
   
  </system.web>

</configuration>

can anybody help me to solve the problem?

Thanks
