I want every button to have binding to this memory card

 class memoryCard : INotifyPropertyChanged
{
    #region c'tor
    public memoryCard(Brush _buttonColor)
    {
        buttonColor=_buttonColor;
    }
    #endregion

    #region allReadyFoundedCard

    bool cardWasfounded = false;
        public bool CardWasfounded
        {
            get
            {
                return cardWasfounded;
            }
            set
            {
                if (cardWasfounded != value)
                {
                    cardWasfounded = value;
                    if (PropertyChanged != null)
                    {
                        PropertyChanged(this,
                        new PropertyChangedEventArgs("cardWasfounded"));

                    }
                }
            }
        }
        #endregion 

    #region colorofbutton
        string name = "sdasdas";
        public Brush buttonColor;
        public Brush ButtonColor
        {
            get
            {
                return buttonColor;
            }
            set
            {
                if (buttonColor != value)
                {
                    buttonColor = value;
                    if (PropertyChanged != null) PropertyChanged(this,
                        new PropertyChangedEventArgs("buttonColor"));
                }
            }
        }
        #endregion

    #region INotifyPropertyChanged Members

        public event PropertyChangedEventHandler PropertyChanged;

        private void NotifyPropertyChanged(String info)
        {
            if (PropertyChanged != null)
            {
                PropertyChanged(this, new PropertyChangedEventArgs(info));
            }
        }

        #endregion
}

whom i want to bind to one of my grids this way :

using this mainwindow class:

 public MainWindow()
    {
        List<List<memoryCard>> lsts = new List<List<memoryCard>>();

        for (int i = 0; i < 5; i++)
        {
            lsts.Add(new List<memoryCard>());

            for (int j = 0; j < 5; j++)
            {
                lsts[i].Add(new memoryCard(Brushes.Green));
            }
        }

        InitializeComponent();

        lst.ItemsSource = lsts; 
    }

Alright, so from what i’ve gathered you’ve got a collection of collections of a custom data type which contains a colour that you’d like to bind to.

So heres a small demo that you should (hopefully) be able to expand.

XAML:

<ItemsControl ItemsSource="{Binding Path=MyCollection}" 
              Height="300" Width="600">
    <ItemsControl.ItemTemplate>
        <DataTemplate>
            <Expander Header="Open Me">
                <ItemsControl DataContext="{Binding}" ItemsSource="{Binding}">
                    <ItemsControl.ItemTemplate>
                        <DataTemplate>
                            <Button DataContext="{Binding}"
                                    Background="{Binding Path=ButtonColor}"
                                    Content="{Binding Path=CardWasFounded}"/>
                        </DataTemplate>
                    </ItemsControl.ItemTemplate>
                </ItemsControl>
            </Expander>
        </DataTemplate>
    </ItemsControl.ItemTemplate>
</ItemsControl>

And in the code behind:

public ObservableCollection<List<memoryCard>> MyCollection {get; set;}

public MainWindow()
{
    DataContext = this;
    MyCollection = new ObservableCollection<List<memoryCard>>();

    for (int i = 0; i < 5; i++)
    {
        List<memoryCard> list = new List<memoryCard>();

        for (int j = 0; j < 5; j++)
        {
            list.Add(new memoryCard(Brushes.Green));
        }
        MyCollection.Add(list);
    }

    InitializeComponent();
}

Is this similar to what you’re trying to do?
