Hi Giuseppe,

Check in /umbraco/editContent.aspx.cs for the controls

The best method might be to use AppBase to inject some jQuery into the page to do what you need.  Check this source for an idea of how to get a handle on the page controls from AppBase

-Tom

Edit - in fact, here is some code I've used that removes the Unpublish button from the properties tab using jQuery & AppBase, might help get you started:

    public class RemoveUnpublishButton : ApplicationBase
    {

        public RemoveUnpublishButton()
        {
            umbracoPage.Load += new umbraco.presentation.masterpages.MasterPageLoadHandler(umbracoPage_Load);
        }

        void umbracoPage_Load(object sender, EventArgs e)
        {
            var page = (umbracoPage)sender;

            if (page.Page.Request.Path.ToLower().Replace((GlobalSettings.Path + "/").ToLower(), "").Contains("editcontent.aspx"))
            {
                var currentDocId = Convert.ToInt32(HttpContext.Current.Request.QueryString["id"]);
                Document d = new Document(currentDocId);
                if (d.ContentType.Alias == "QuizChoice" || d.ContentType.Alias == "QuizChoiceWithImage" || d.ContentType.Alias.StartsWith("Question-"))
                {
                    string s = "<script type='text/javascript'>";
                    s += "$(document).ready(function() {";
                    s += "$('#body_UnPublishButton').hide();";
                    s += "});";
                    s += "</script>";
                    page.Page.ClientScript.RegisterClientScriptBlock(this.GetType(), "jshideunpublish", s);
                }
            }
        }
    }

Thanks Tom, this is a great help for me!

Have a good day
