I know howto generate TabItems on the fly (runtime) but I need a way to check if the tabItem exists before it is created.

C#

public void NewTabItem(object sender, RoutedEventArgs e)
{
  if( .........)
  {
    this.MyTabControl.SelectedIndex =
      this.MyTabControl.Items.Add(new TabItem { Header = "A1"});
  }
}

Solution 1

This question is really old but still... it is nice to have an answer

C#

        private bool createTab( List<string> tabNames, NIC savedSetting )
        {
            string newTabeName = savedSetting.AdapterName;
            bool tabExists = false;

            foreach(var checkTab in tabSettings.Items)
            {
                //cast as a TabItem to get access to the properties
                if( ( ( TabItem )checkTab ).Header.ToString() == newTabeName )
                {
                    tabExists = true;
                    break;
                }
            }

            if( !tabExists )
            {
                var NIC_Tab = new TabItem()
                {                    
                    Header = newTabeName,
                    Content = new TabDataControl(),
                    DataContext = savedSetting
                };
                tabSettings.Items.Add( NIC_Tab );
            }
            return tabExists;
        }
</string>

        {
            string newTabeName = savedSetting.AdapterName;
            bool tabExists = false;

<pre>
        foreach(var checkTab in tabSettings.Items)
        {
            //cast as a TabItem to get access to the properties
            if( ( ( TabItem )checkTab ).Header.ToString() == newTabeName )
            {
                tabExists = true;
                break;
            }
        }

        if( !tabExists )
        {
            var NIC_Tab = new TabItem()
            {
                Header = newTabeName,
                Content = new TabDataControl(),
