PageChangedOnPublish

Is it possible to affect the "Page changed on publish"-checkbox in edit mode for a page to make it set by default (and allow the editor to manually uncheck it)? I've tried hooking up EPDataFactory_LoadedPage to set e.Page.Property["PageChangedOnPublish"].Value=true, but it doesn't seem to affect the checkbox at all.

I've just made this (this morning actually). I looked around a bit and found a code sample that I modified. This creates a hidden editpanel that can be used for other purposes as well, such as hooking on javascript on submit button.


    [EPiServer.PlugIn.GuiPlugIn(DisplayName = "hidden",
         Description = "edit hooks",
         Area = EPiServer.PlugIn.PlugInArea.EditPanel,
         Url = "~/templates/Plugins/EditHiddenHooks.ascx")
    ]
    public class EditHiddenHooks : UserControlBase, ICustomPlugInLoader
    {
        PlugInDescriptor[] ICustomPlugInLoader.List()
        {
            PlugInDescriptor[] plugins = new PlugInDescriptor[0];

            this.PageBase.PreRender += new EventHandler(Page_PreRender);

            return plugins;
        }

        private void Page_Load(object sender, System.EventArgs e)
        {
        }


        #region Web Form Designer generated code
        override protected void OnInit(EventArgs e)
        {
            //
            // CODEGEN: This call is required by the ASP.NET Web Form Designer.
            //
            InitializeComponent();
            base.OnInit(e);
        }

        ///

        /// the contents of this method with the code editor.
