So you have a XAML page, and in the code behind you have a couple of variables. How do you bind the elements with the local variables?

    To begin with, you will need the property with which you can bind the XAML element.
    Implement the following interface… INotifyPropertyChanged

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

       int _hour;
       public int Hour
       {
           get { return _hour; }
           set {
               if (value != _hour)
               {
                   _hour = value;
                   NotifyPropertyChanged("Hour");
               } 
           }
       }

    Inside the constructor of your page, add the following line…

         this.DataContext = this;

    Now, bind as usual…

<TextBlock Text="{Binding Hour}" />

    Yep, that simple!

Until next time,
