The Rectangle element is used to draw rectangles in report. All the properties of the Rectangle have been discussed in the Common Properties section. Note that you can turn the four sides of the rectangle on and off independently, so this is a good component to use to ensure your lines are horizontal or vertical. The Line shape is not supported on certain output types, because they don't support arbitrary shape rendering (e.g. HTML) - where you only need horizontal or vertical lines you might prefer to use a Rectangle with some sides turned off, because HTML can display these.
