Также имеется функция для вставки в новые "табы" контента

code c#:

        private TabItem AddTabItem(string tabHeader, string tabName, object tabContent)
        {
            int count = _tabItems.Count;

            // create new tab item
            TabItem tab = new TabItem();

            tab.Header = tabHeader;
            tab.Name = tabName;
            tab.Tag = _tabItems.Count;
            tab.HeaderTemplate = tabControl.FindResource("TabHeader") as DataTemplate;

            // add controls to tab item
            if(tabContent != null)
            tab.Content = tabContent;

            // insert tab item 
            _tabItems.Insert(count, tab);

            tab.Focus();

            return tab;
        } // End Of AddTabItem
