Question

public partial class MainWindow : Window

    //use DataContaxt method here without using new object
    enter code here

}


public partial class DetailedBookView : UserControl
{
    int DataContaxt = 10;
}

Answer 1

Make Method and fields which you want to use in another class of DetailedBookView static. Doing so, you can use these methods and fields with the class name directly.

public partial class DetailedBookView : UserControl
{
    static int DataContaxt = 10;
}

Now you can use DataContaxt directly as:

public partial class MainWindow : Window
{    
    int a = DetailedBookView.DataContaxt;

}
