Answer 1

Why not just bind the Text property to a property on your view model? That way you get notified when it has changed, and also get the new value:

public string MyData
{
    get { return this.myData; }
    set
    {
        if (this.myData != value)
        {
            this.myData = value;
            this.OnPropertyChanged(() => this.MyData);
        }
    }
}
