Coding Within Form

I wanted to do some thing like this but I keep getting the Container Not Defined error. Can someone help?

Form Side:

<% if DataBinder.Eval(Container.DataItem,"Checkbox") = 1 %>
<asp:CheckBox ID = "chkOne" Runat = "server" Text='<%# DataBinder.Eval(Container.DataItem,"TestOne") %>' />
<% else %>
<asp:Label ID = "lblOne" Runat = "server" Text='<%# DataBinder.Eval(Container.DataItem,"TestOne") %>' />
<% end if %>

Server Side:
Private Sub Page_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
Dim conn As SqlConnection = New SqlConnection(ConfigurationSettings.AppSettings("SQLServer"))
Dim cmd As SqlCommand = New SqlCommand
Dim ds As DataSet = New DataSet
Dim da As SqlDataAdapter = New SqlDataAdapter
cmd.CommandText = "Select * from Test"
cmd.Connection = conn
da.SelectCommand = cmd
da.Fill(ds)
Repeater1.DataSource = ds
Repeater1.DataBind()
End Sub
