method in partial class not listed in intellisense

[oiloiloil]

In VS 2010 I have created a test method in partial class stored in Default.Partial.aspx.cs within the same directory as Default.aspx.cs but it isn't recognized by the Default.aspx.cs\[code\]using System;using System.Collections.Generic;using System.Linq;using System.Web;/// <summary>/// Summary description for Default/// </summary>public partial class _Default : System.Web.UI.Page{ private void test() { }}\[/code\]Code of default.partial.cs\[code\]using System;using System.Collections.Generic;using System.Linq;using System.Web;using System.Web.UI;using System.Web.UI.WebControls;public partial class _Default : System.Web.UI.Page{ protected void Page_Load(object sender, EventArgs e) { test(); }}\[/code\]Update: if I add same namespace to both I get even weird message error I really don't understand partial class in asp.net whereas with winform I never encountered such problem !
