Command Routing and event routing in WPF are two very beginner headaches concepts, and for command routing, it can be understood that system (WPF) defines a series of actions that can be used directly in an application. For example, you can simply do this by defining a series of menus to copy, cut, and paste the text boxes in the form: 1:　 2:　　　 3:　　　　　 4:　　　　　 5:　　　 6:　　　 7:　　　　　 8:　　　 　　　　 9:　　　　　　　　　　

First, Canvas Layout controls for absolute positioning of neutron elements in WPF Its child elements define the width and height of the element using width and height Use Convas.left (convas.right), Convas.top (Convas.bottom) to define the relative position of the Convas container If Convas.left and Convas.right, Convas.top and Convas.bottom are present at the same time, Convas.left, Convas.top takes precedence For example: 1:　 2:　　　 3:　　　 4:
