Création d'un custom button

Bonjour à tous.

J'essaye de créer un bouton qui possèderait un champs texte supplémentaire.

Je me suis dis que j'allais créer un button et créer un style afin d'avoir ce que je veux.

J'ai donc créé ce style :

Mais comment via code atteindre un champs contenu dans un style???
Plus particulièrement ici le champs TxtCount.

Mais je ne voyais pas comment faire via le style.
J'ai donc créé un CustomControl :

Code:

1
2
3
4
5
6
7
8
9
10
11
12
13
14
15
16
17
18
19
20
21
22
23
24
25

public class ButtonCount : Button, INotifyPropertyChanged
    {
        int _Count;
 
        static ButtonCount()
        {
            DefaultStyleKeyProperty.OverrideMetadata(typeof(ButtonCount), new FrameworkPropertyMetadata(typeof(ButtonCount)));
        }
 
        public int Count
        {
            get
            { return _Count; }
            set
            { if(value!=_Count)_Count = value; OnPropertyChanged("Count"); CountString = _Count.ToString(); }
        }
        public String CountString
        {
            get
            { return _Count.ToString(); }
            set
            { OnPropertyChanged("CountString"); }
        }
 
        #region INotifyPropertyChanged Members
        public event PropertyChangedEventHandler PropertyChanged;
        protected void OnPropertyChanged(string propertyName)
        {
            if (PropertyChanged != null)
                PropertyChanged(this, new PropertyChangedEventArgs(propertyName));
        }
        #endregion
    }

Puis dans mon style j'ai fais une tentative de binding sur la propriété text:

Code:

1
2
 
<TextBlock x:Name="TxtCount" TextWrapping="Wrap" Text="{Binding CountString}" etc.../>

Dans ma fenêtre j'ai déclaré mon button comme cela:

Code:

1
2
 
<MyCustomControls:ButtonCount Style="{DynamicResource BtnCount}" Click="ButtonCount_Click" Width="100" Height="40" Content="Name"/>

Le style est bon.
Mais aucune réaction pour mon TxtCount qui reste vide.
Pas à pas j'ai vu que ça passait bien dans le set de mon CountString.

C'est surement ce binding dans le style qui n'est pas bon:

Code:

1
2
 
<TextBlock x:Name="TxtCount" TextWrapping="Wrap" Text="{Binding CountString}" etc.../>

J'ai beau regarder des tutos sur les customcontrols, je ne vois pas trop de cas similaire au mien.

Si quelqu'un a une piste merci.
