c# dynamicly adding item in listbox - Items not showing

Question

I'm trying to dynamicly add items (textbox and button) into a listbox.

This is my xaml :

<ListBox x:Name="projects_list" Height="459" Canvas.Left="20" Canvas.Top="86" Width="755">
    <ListBox.ItemTemplate>
        <DataTemplate>
            <StackPanel Orientation="Vertical" Height="42">

            </StackPanel>
        </DataTemplate>
    </ListBox.ItemTemplate>
</ListBox>

And, in the StackPanel I want to have my 2 buttons.

Inside a foreach , I create the buttons like this:

items.ForEach(delegate (Projects project)
{
    Button txt = new Button(); // NAME
    txt.Height = 32;
    txt.Width = 320;
    txt.Content = project.name;

    Button gen_token = new Button(); 
    gen_token.Height = 26;
    gen_token.Width = 180;
    gen_token.Content = "Generate";

    this.projects_list.Items.Add(txt); 
    this.projects_list.Items.Add(gen_token);  
}

But, When I add the elements into my ListBox , nothing appears. Even though, there is a good number of StackPanel s in my list.

Any idea? Thanks!

EDIT : If I Had

      <Button Content="{Binding}" ></Button>

Into the stackPanel , My buttons are showing, but not really has I want to, they are one by stackpanel and I want both buttons on every panel ..

EDIT 2 : So, I tried this :

        public List<Dictionary<string, Button>> Items { get; set; }
        ....
        Items = new List<Dictionary<string, Button>>();
        DataContext = this;

And later in the each

         Dictionary<string, Button> dict = new Dictionary<string, Button>() { { "name", txt }, { "token", gen_token } };
                Items.Add(dict);

So In my xaml, I have :

            <ListBox x:Name="projects_list" Height="459" Canvas.Left="20" Canvas.Top="86" Width="755" ItemsSource="{Binding Items}"  >
            <ListBox.ItemTemplate>
                <DataTemplate>
                    <StackPanel Orientation="Vertical" Height="42">
                        <Button Content="{Binding Path=name}" ></Button>
                        <Button Content="{Binding Path=token}" ></Button>

                    </StackPanel>
                </DataTemplate>
            </ListBox.ItemTemplate>
        </ListBox>

But still, nothing appears :(

Answer 1

A quick example:

Window.Xaml

  <ListBox ItemsSource="{Binding Items}">
        <ListBox.ItemTemplate>
            <DataTemplate>
                <Button Content="{Binding}" />
            </DataTemplate>
        </ListBox.ItemTemplate>
    </ListBox>

Code behind

public partial class MainWindow : Window
{
    public ObservableCollection<string> Items { get; set; }
    public MainWindow()
    {
        InitializeComponent();
        Items = new ObservableCollection<string> { "Item 1", "Item2" };
        DataContext = this;
    }
}

This is just a quick example to give you an idea. You would probably do a ViewModel instead of code behind.
