In my app i used WPF TabControl, I want click event on TabItem, how do i do it?

Xaml:

<TabControl 
      SelectionChanged="TabControl_SelectionChanged"
      TabStripPlacement="Left">
      <TabItem Header="Grass" x:Name="Tab1"></TabItem>

I Made Some Changes To Your Code Which Worked Successfully As Below:

private void TabControl_SelectionChanged(object sender, SelectionChangedEventArgs e)
{
    Dispatcher.InvokeAsync(() =>
    {
        string Tabitem = ((sender as TabControl).SelectedItem as TabItem).Name as string;
        switch (Tabitem)
        {
            case "Tab1":
                MessageBox.Show("you chose Grass");
                break;
            case "Tab2":
                MessageBox.Show("you chose Tree");
                break;
            case "Tab3":
                MessageBox.Show("you chose Flower");
                break;
            default:
                return;
        }

    });
}

Note:

The "Dispatcher.InvokeAsync" code prevents threads from interfering
