            string tabName = (sender as Button).CommandParameter.ToString();
 
            var item = tabDynamic.Items.Cast<TabItem>().Where(i => i.Name.Equals(tabName)).SingleOrDefault();
 

            TabItem tab = item as TabItem;
 
            if (tab != null)
            {

                {
                    MessageBox.Show("Cannot remove last tab.");
                }
                else if (MessageBox.Show(string.Format("Are you sure you want to remove the tab '{0}'?", tab.Header.ToString()),
                    "Remove Tab", MessageBoxButton.YesNo) == MessageBoxResult.Yes)
                {
                    // get selected tab
                    TabItem selectedTab = tabDynamic.SelectedItem as TabItem;
 
                    // clear tab control binding

                    _tabItems.Remove(tab);
 
                    // bind tab control
                    tabDynamic.DataContext = _tabItems;
 
                    // select previously selected tab. if that is removed then select first tab
                    if (selectedTab == null || selectedTab.Equals(tab))
                    {
                        selectedTab = _tabItems[0];
