Page.Load should be fine. This is my test C# code:

namespace NotImportant
{
    public partial class Testing : System.Web.UI.Page
    {
        protected void Page_Load(object sender, EventArgs e)
        {
            TextBox1.AutoPostBack = true;
            TextBox1.TextChanged += new EventHandler(TextBox1_TextChanged);
        }

        void TextBox1_TextChanged(object sender, EventArgs e)
        {
            System.Diagnostics.Debugger.Break();
        }
    }
}

The eventhandler fires as expected - not sure what is different in your case......
