How to retrieve a stored session of datagrid?

In my asp.net web form [findstores.aspx.vb], I saved a session for the datagrid to Session("StoreListSession") = dvStorelist. After user clicked "Apply this job!" button (a ButtonColumn) in the datagrid item, the user will be redirected to another page(OnlineApp.aspx), where the "Cancel" button on that page should bring the user back to the "findstores.aspx" page, so that user can click other items of the datagrid.

[In "onlinapp.aspx"]
Sub btnCancel_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnCancel.Click
Response.Redirect("FindCrewJobs.aspx")
End Sub

** How can I get the stored datagrid session when the page is redirected to "findstores.aspx", so that user will see the original datagrid in findstores.aspx page ????

[In "findstores.aspx.vb"]
Private Sub Page_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
If Not IsPostBack Then
Dim State As String
Dim ds As DataSet
Dim dr As SqlDataReader
State = Request.QueryString("State")

'Generate store list from querystrings
If Request.QueryString("State") <> Nothing Then

ds = New DataSet
If Not conDWDb.State = ConnectionState.Open Then
conDWDb.Open()
End If
Dim cmdAddressInfo As New SqlCommand
Dim dtrAddressInfo As SqlDataReader
With cmdAddressInfo
.Connection = conDWDb
.CommandText = "Select Store_Num ,Store_Address+', '+City+', '+State+' '+Zip_Code AS Address,Store_Fax from store_table where co_code=1 and store_mgr is not null and State=@State"
.Parameters.Add("@State", SqlDbType.Char).Value = State
End With
Dim adpt As SqlDataAdapter = New SqlDataAdapter(cmdAddressInfo)
adpt.Fill(ds, "StoreList_Table")
dgcrewstores.DataSource = ds
Dim dvStorelist As New DataView(ds.Tables("Storelist_Table"))
Session("StoreListSession") = dvStorelist
dgcrewstores.DataBind()
End If
conDWDb.Close()
End If
End Sub
