WPF TabControl - TabItem [英] WPF TabControl - TabItem

问题描述

我知道如何动态生成TabItems（运行时）但是我需要一种方法来检查tabItem在创建之前是否存在。

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

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

推荐答案

检查MyTabControl中的值，如果标头已经存在或者某些数据在items。

check the values in the MyTabControl if the header already exists or some data in the items.

这个问题真的很旧但是仍然......很高兴有答案

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

        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>

private bool createTab( List<string> tabNames, NIC savedSetting )
        {
            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(),
                DataContext = savedSetting
            };
            tabSettings.Items.Add( NIC_Tab );
        }
        return tabExists;
    }
