Extending Umbraco

I'm using the Load page event to add a menu button for a specific content type. However it appears the event is called twice which results in the button being added twice. Any ideas?

private void umbracoPage_Load(object sender, System.EventArgs e)
        {
            umbracoPage page = (umbracoPage)sender;
            string path = page.Page.Request.Path.Replace((umbraco.GlobalSettings.Path + "/"), "");

            if (string.Compare(path, "editcontent.aspx", StringComparison.OrdinalIgnoreCase) != 0)
            {
                return;
            }

            ContentPlaceHolder cph = (ContentPlaceHolder)page.FindControl("body");

            Control c2 = cph.FindControl("TabView1");

            if (c2 == null)
            {
                return;
            }
            
            ContentControl cc = (ContentControl)c2;
            string docTypeAlias = cc.ContentObject.ContentType.Alias;

            if (string.Compare(docTypeAlias, "WarrantyForm", StringComparison.OrdinalIgnoreCase) != 0)
            {
                return;
            }

            TabView tabView = (TabView)c2;
            ArrayList panels = tabView.GetPanels();
            TabPage tabPage = (TabPage)panels[0];

            tabPage.Menu.InsertSplitter();
            MenuIconI ni = tabPage.Menu.NewIcon();

            ni.ImageURL = "images/editor/approve.gif";
            ni.AltText = "Approve This Warranty Claim";

            string approvalFormUrl = umbraco.GlobalSettings.Path + "/plugins/approveform.aspx";
            ni.OnClickCommand = string.Format("document.location.href='{0}'", approvalFormUrl);
        }

Hi seanrock, try this:

privatevoid umbracoPage_Load(object sender,System.EventArgs e)
        { if(!IsPostBack){
            umbracoPage page =(umbracoPage)sender;
            string path = page.Page.Request.Path.Replace((umbraco.GlobalSettings.Path+"/"),"");

            if(string.Compare(path,"editcontent.aspx",StringComparison.OrdinalIgnoreCase)!=0)
            {
                return;
            }

            ContentPlaceHolder cph =(ContentPlaceHolder)page.FindControl("body");

            Control c2 = cph.FindControl("TabView1");

            if(c2 ==null)
            {
                return;
            }
            
            ContentControl cc =(ContentControl)c2;
            string docTypeAlias = cc.ContentObject.ContentType.Alias;

            if(string.Compare(docTypeAlias,"WarrantyForm",StringComparison.OrdinalIgnoreCase)!=0)
            {
                return;
            }

            TabView tabView =(TabView)c2;
            ArrayList panels = tabView.GetPanels();
            TabPage tabPage =(TabPage)panels[0];

            tabPage.Menu.InsertSplitter();
            MenuIconI ni = tabPage.Menu.NewIcon();

            ni.ImageURL="images/editor/approve.gif";
            ni.AltText="Approve This Warranty Claim";

            string approvalFormUrl = umbraco.GlobalSettings.Path+"/plugins/approveform.aspx";
            ni.OnClickCommand=string.Format("document.location.href='{0}'", approvalFormUrl);
        } }

Marcio Goularte, thanks but that isn't going to work. IsPostBack isn't part of the ApplicationBase which this class inherits from. umbracoPage does inherit from System.Web.UI.MasterPage however the IsPostBack property is always false.

Sorry! I have not seen right. I thought it was the Page_Load event, I replied without reading. Unfortunately I have no idea. Your code looks correct.
