How do you select rows from one gridview to populate another gridview on a different page?

Hi All,

There have been some questions asked about his but am still unsure how to apply to my situation. Basically..

Using Visual Web developer 2005 (VB.Net),

I have a database  table (SQL Server Express 2005) called Contact that has ContactID, FirstName, LastName, Company and Email for columns. ContactID is the primary key.

I have a aspx page called searchresults that has a gridview to show the contact data. (ContactID is not included in the gridview) There are checkboxes next to each row done using asp like this
<ItemTemplate>
             <asp:CheckBox ID="chkSelect" runat="server"  />
</ItemTemplate>

The data itself is generated using code like this...

    Public Function generatedata(ByVal conn As String, ByVal query As String) As DataTable

        Dim connection As New SqlConnection(conn)
        Dim command As New SqlCommand
        command.Connection = connection
        command.CommandType = CommandType.Text
        command.CommandText = query
        Dim adapter As New SqlDataAdapter(command)
        Dim buffer As New DataTable

        adapter.Fill(buffer)

        Return buffer
    End Function


    Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
        Dim conn_string, query As String
        Dim results As New DataTable

        conn_string = "Data Source=.\SQLEXPRESS;AttachDbFilename=" & "C:\Documents and Settings\mk\My Documents\Visual Studio 2005\WebSites\Contacts\App_Data\Contacts.mdf" & ";Integrated Security=True;Connect Timeout=30;User Instance=True"

'although this is a search results page, this query is used to populate the gridview with data for 'development purposes, the search function has not been implemented yet
        query = "select FirstName As [First Name], LastName As [Last Name], Email from Contact WHERE ContactID<150"

        results = generatedata(conn_string, query)

        GridView1.DataSource = results
        GridView1.DataBind()
    End Sub

What I want to do is select the rows I am interested in, click a button, go to a different page such as details.aspx and fill the gridview with the rows I have selected.

My coding ability in all honesty is not that great I am only just about getting to grips with vb.net, I would really appreciate it if anyone could show us how this could be done. I'll be manipulating the data in the gridviews in certain ways which isn't really that important at this moment in time - so long as I can understand how to get data from gridview to gridview on different pages I think I should be able to manage. My apologies about the length of this question.
