I am assuming you know nothing about AJAX ( which has no OnNavigate event ) and you're using the ASP.NET AJAX library, in which case, this is the wrong forum. Christian Graus Driven to the arms of OSX by Vista. Read my blog to find out how I've worked around bugs in Microsoft tools and frameworks.

Found what caused problem. I forgot to add scriptmanager as triger to updatepanel, however, why there is no hint everywhere i`we looked about that. :( It`s nothing to wory before something happen and when it happents it`s alredy to late to wory! :)

I know that :( But I do not care about viewstate or Postback, all controls that should talk to server are in main page, not in update panel, only thing that do not work as wanted is ScriptManagers OnNavigate event. It fires too late. I need that event to handle f5, back and forward. If controls are added as fallows: protected void mi1_click(object sender, EventArgs e) { test(); } all is ok :( But in this case: public void OnNavigateHistory(object sender, HistoryEventArgs e) { test(); } it will not work :( void test() { //This line works fine in both cases. It sets couple of properties, as label texts and session variables. set_title("Test title"); //Instead of button I need my usercontrol, but even button will not show up. Button btn = new Button(); btn.Text = "I bitīt matos!!!!!!!!!!!"; PHolder.Controls.Clear(); PHolder.Controls.Add(btn); sm.AddHistoryPoint("aa", "bb"); } It`s nothing to wory before something happen and when it happents it`s alredy to late to wory! :) modified on Friday, July 31, 2009 3:15 PM

Slow down. What you are asking does not make sense. What is it that you are trying to do? And please in the best English that you can and the best description that you can. Asking questions and then deleting them does not help. Why is common sense not common? Never argue with an idiot. They will drag you down to their level where they are an expert.

iDataClient is proxy class created by VS 2008. clsData on client side is my helper class that calls methods on proxy class. Problem was, that I have one GUI for local data and remote data, and I do not want to write allmoast same code twice, as there is much other work to be done and I work alone.
