I've made a custom filter that is supposed to filter out a cetanin pagetype by it's PageTypeName prop. The thing is that it seems that the Filter event is never trigged by EP. I've tryed to debugg by attatching the asp process and it never get's there. I have tryed to put the filter event handler in both OnInit, PageLoad and in a separate class. here is the code: protected PageTree PageTreeControl; private MenuList _menuListControl; private void Page_Load(object sender, EventArgs e) { if(_menuListControl != null) { PageTreeControl.DataSource = _menuListControl; } PageTreeControl.Filter += new FilterEventHandler(PageTreeControl_Filter); if(!IsPostBack) { PageTreeControl.DataBind(); } } override protected void OnInit(EventArgs e) { InitializeComponent(); base.OnInit(e); PageTreeControl.Filter += new FilterEventHandler(PageTreeControl_Filter); } private void PageTreeControl_Filter(object sender, EPiServer.Filters.FilterEventArgs e) { PageDataCollection pdc = e.Pages; for(int i=0; i< pdc.Count; i++) { if(pdc[i].PageTypeName.Equals("Pagetype to filter")) { pdc.RemoveAt(i); i--; } } }
