Stack control

•The StackPanel control provides the ultimate in control layout flexibility on a user interface.
•By using the control you can stack controls on top of each other vertically or display them horizontally.
•The StackPanel will place its children in either a column (default) or row.
•This is controlled by the Orientation property. A vertical StackPanel can have its width and height specified;
•By using the StackPanel you can arrange controls on an interface without defining absolute positions for each control.
•if the height is not specified it will take up as much space vertically as is required to fit all of its children.
•An unconstrained horizontal StackPanel will be as wide as necessary to hold all of its children, and as tall as the tallest child. :
