How can i add RadWindow from ContentPage (Default.aspx) to the RadWindowManager in MasterPage?

Answer 1

RadWindow:

RadWindow radwindowNews = new RadWindow();
radwindowNews.ID = "RadWindow1";
radwindowNews.Width = 820;
radwindowNews.Height = 600;
radwindowNews.Modal = true;
radwindowNews.ReloadOnShow = true;
radwindowNews.AutoSize = false;
radwindowNews.ShowContentDuringLoad = false;
radwindowNews.Behaviors = WindowBehaviors.Close;

Add the RadWindow:

RadWindowManager radManager =
    (RadWindowManager)this.Master.FindControl("MasterRadWindowManager");
radManager.Windows.Add(radwindowNews);
