            <!-- I was about to add the Robot Peg here and animate it -->

Code Behind:

public partial class GridRobot : Window
{
    public GridRobot()
    {
        InitializeComponent();
        DataContext = new GridRobotViewModel();
    }
}

View Model:

public class GridRobotViewModel: PropertyChangedBase
{
    private int _size;
    public int Size
    {
        get { return _size; }
        set
        {
            _size = value;
            OnPropertyChanged("Size");
            CreateItems();
        }
    }

    private ObservableCollection<GridItem> _squares;
    public ObservableCollection<GridItem> Squares
    {
        get { return _squares ?? (_squares = new ObservableCollection<GridItem>()); }
    }

    private ObservableCollection<GridItem> _route;
    public ObservableCollection<GridItem> Route
    {
        get { return _route ?? (_route = new ObservableCollection<GridItem>()); }
    }

    private void CreateItems()
    {
        Squares.Clear();
        Route.Clear();
        for (int i = 0; i < Size; i++)
        {
            for (int j = 0; j < Size; j++)
            {
                Squares.Add(new GridItem() {Row = i, Column = j});
            }
        }
    }

    private Command<GridItem> _goToCommand;
    public Command<GridItem> GoToCommand
    {
        get { return _goToCommand ?? (_goToCommand = new Command<GridItem>(Goto){IsEnabled = true}); }
    }

    private void Goto(GridItem item)
    {
        if (item.PathIndex == null)
        {
            item.PathIndex = Squares.Max(x => x.PathIndex ?? 0) + 1;

            Route.Add(item);    
        }
    }
}

Data Item:

public class GridItem: PropertyChangedBase
{
    public int Row { get; set; }

    public int Column { get; set; }

    private int? _pathIndex;
    public int? PathIndex
    {
        get { return _pathIndex; }
        set
        {
            _pathIndex = value;
            OnPropertyChanged("PathIndex");
        }
    }
}

Support Classes for MVVM:

public class PropertyChangedBase:INotifyPropertyChanged
{
    public event PropertyChangedEventHandler PropertyChanged;

    protected virtual void OnPropertyChanged(string propertyName)
    {
        Application.Current.Dispatcher.BeginInvoke((Action) (() =>
            {
                PropertyChangedEventHandler handler = PropertyChanged;
                if (handler != null) handler(this, new PropertyChangedEventArgs(propertyName));
            }));
    }
}

public class Command<T>: ICommand
{
    public Action<T> Action { get; set; }

    public void Execute(object parameter)
    {
        if (Action != null && parameter is T)
            Action((T)parameter);
    }

    public bool CanExecute(object parameter)
    {
        return IsEnabled;
    }

    private bool _isEnabled;
    public bool IsEnabled
    {
        get { return _isEnabled; }
        set
        {
            _isEnabled = value;
            if (CanExecuteChanged != null)
                CanExecuteChanged(this, EventArgs.Empty);
        }
    }

    public event EventHandler CanExecuteChanged;

    public Command(Action<T> action)
    {
        Action = action;
    }
}

Result:

• Just copy and paste my code in a File -> New Project -> WPF Application and see the results for yourself.
• You said 10 x 10, but I went a step further and added a Slider to make the grid size customizable.
• Clicking on any cell will make it be queued as part of the Route.
• Fully Resolution Independent.
• I was about to start putting some really nice stuff on it (animations, robot movement represented by an ellipse, Lines for the Path, etc).
• Forget winforms, it's useless.
