Figure 8-6 The WrapPanel Layout control
Figure 8-6 demonstrates how you can lay out a group of controls to fill an available space. In the case of the CheckBox controls, the Orientation of the WrapPanel is set to Vertical (the default is Horizontal). When the number of CheckBox controls fills the vertical column, remaining CheckBoxes wrap to the next column. Because the sizes of the CheckBox controls are the same, you have a uniform layout, which is easier than trying to do the same thing with a Grid or other layout control. The final layout control we’ll discuss is the Canvas, which is next.
Canvas Layout
There are times when you might want to perform explicit layout of controls. If you were building a diagramming application or a drawing program, or if you just wanted to explicitly specify the location of controls, the Canvas layout will work fine. Figure
The Rectangle and Ellipse controls were dragged and dropped from the Toolbox onto the Canvas control. Notice the Canvas.Left, Canvas.Top, Width, and Height properties in the Properties window, demonstrating the absolute positioning of the selected Ellipse control.
