是否可以绑定到ColumnSpan属性

绑定ColumnSpan属性时遇到问题。经过几个小时的调试，我想知道这是否可能。

public partial class MainPage : PhoneApplicationPage, INotifyPropertyChanged
{
    public event PropertyChangedEventHandler PropertyChanged;
    private int myProperty;
    public MainPage()
    {
        InitializeComponent();
        Binding binding = new Binding("MyProperty");
        binding.Source = this;
        btn0.SetBinding(Grid.ColumnSpanProperty, binding);
    }
    public int MyProperty
    {
        get
        {
            return myProperty;
        }
        set
        {
            myProperty = value;
            OnPropertyChanged("MyProperty");
        }
    }
    protected virtual void OnPropertyChanged(string property)
    {
        if (PropertyChanged != null)
        {
            PropertyChanged(this, new PropertyChangedEventArgs(property));
        }
    }
}

是否可能绑定到Grid.Column而不绑定到Grid.ColumnSpan？如果ColumnSpan有可能，我做错了什么？
