Handle GridView1_RowUpdating

Hey guys,

I'm the type of guy who likes to avoid designer code, so I'm trying to handle the GridView1_RowUpdating of my GridView.

Code:

---

protected void GridView1_RowUpdating(object sender, GridViewUpdateEventArgs e)
    {
        foreach (DictionaryEntry entry in e.NewValues)
        {
            Response.Write("This does not print<br>");
            Response.Write(entry.Value);
        }

        Response.Write("This does print<br>");


        GridView1.EditIndex = -1;
        GridView1.DataSource = Session["SessionDataViewTable"];
        GridView1.DataBind();
    }

---

For some reason nothing is found in my e.NewValues collection. Even though I made an entry, and clicked on Update.
Am I missing something?

Some more specs on this issue.
-Visual Studio 2005
-Windows XP
-C# Code used in ASP.NET web application


Let me know if you need more info from me. Thanks. :)
