在C＃WPF中，如何设置以某种颜色突出显示的标签并以编程方式添加鼠标事件处理程序？

Question

So I've set up a TreeView and inside it, I've placed Labels which I need to be highlighted permanently in either red or green on initialization. (Like in the picture) Does anyone know how to do this programmatically? I instantiate the labels like this

Label l = new Label() { Content = roomnumber };

ALSO!! I've been trying to link it to handle a mousedoubleclick event but doing this doesn't work either. any ideas?

Label l = new Label() { Content = roomnumber, MouseDoubleClick="Window_MouseDoubleClick" };

You can set BackgroundProperty of Label as like below.

//Green Colored Background
Label label = new Label() { Content = roomnumber, Background = new System.Windows.Media.SolidColorBrush(System.Windows.Media.Colors.Green) };
//Red Colored Background
Label label = new Label() { Content = roomnumber, Background = new System.Windows.Media.SolidColorBrush(System.Windows.Media.Colors.Red) };

Label also has a MouseDoubleClick event you can subscribe this.

label.MouseDoubleClick += label_MouseDoubleClick;
....
void label_MouseDoubleClick(object sender, System.Windows.Input.MouseButtonEventArgs e)
{
    ////MessageBox.Show(((Label)sender).Content.ToString());
}
