Add Item to ListBox from TextBox

I have this ListBox:

<ListBox x:Name="PlaylistList" AlternationCount="2" SelectionChanged="DidChangeSelection">
        <ListBox.GroupStyle>
            <GroupStyle />
        </ListBox.GroupStyle>
        <ListBox.ItemTemplate>
            <DataTemplate>
                <TextBlock Text="{Binding Name}"/>
            </DataTemplate>
        </ListBox.ItemTemplate>
    </ListBox>

And i want to add option to add new item to the ListBox. And i want to do it by adding a TextBox to the ListBox when the user press a Button and then the user press enter and add the text in the TextBox to the ListBox.

I try to add text box to the listbox but i can add only one type of ListBox.ItemTemplate, how can i handle it?

Write this code when your button is clicked so that the textbox text will be added to the listbox.

private void addEventButton_Click(object sender, EventArgs e)
    {


        // Adds events to listbox. 
       if (this.titleTextBox.Text != "")
        {
            listBox1.Items.Add(this.titleTextBox.Text); 
            listBox2.Items.Add(this.titleTextBox.Text);
            this.titleTextBox.Focus();
            this.titleTextBox.Clear();

         }
      }

Updated to add textbox inside Listbox:

To add new item into ListBox, in Button Click code-behind do:

TextBox TextBoxItem = new TextBox();
// set TextBoxItem properties here
PlaylistList.Items.Add(TextBoxItem);

Your ListBox:

<ListBox
    Name="MyListBox"
    ItemsSource="{Binding Path=Reason}"
    DisplayMemberPath="Description"/>

Make a ObversableCollection for the Items of the ListBox

public ObservableCollection<IdObject> items
{
    get { return (ObservableCollection<IdObject>)GetValue(ApplicationsProperty); }
    set { SetValue(ApplicationsProperty, value); }
}

items = new ObservableCollection<IdObject>();

My ID-Object in this case has the following properties:

private int _id = 0;
private string _description = "";

Bind the collection to the ListBox:

MyListBox.ItemsSource = items;

Then make a TextBox with a Button, and an event for pressing the button, where you add the text to the observable collection:

items.Add(new IdObject(someId, TextBox.Text));

The ListBox will update, when the ObservableCollection is changed
