AbsoluteLayout.LayoutBounds -- -A comma-separated list—possibly with spaces—of four values that specify the bounding rectangle's position and dimensions. The first two values in the list must represent numbers. The latter two values may each either be numbers, or the string "AutoSize". The -AbsoluteLayout.LayoutFlags attached property determines how the values in the list are interpreted to create the bounding rectangle.
- -
-
AbsoluteLayout.LayoutFlags -- -- -enumeration value names: All ,None ,HeightProportional ,WidthProportional ,SizeProportional ,XProportional ,YProportional , orPositionProportional . Application developers can combine any of these flags together by supplying a comma-separated list.

-
- For elements whose height and width fit on the screen, proportional position dimensions in the range [0,1] represent elements that are completely on the screen, regardless of whether the height, width, or both are specified in device or proportional units. The above point means that, to specify an element in the lower right hand corner of the screen and that is half as wide and half as all as the screen, with a value of All , the application developer would specify "1.0, 1.0, 0.5, 0.5".The app developer can inadvertently cause child elements for which one or both size dimensions were specified proportionally to be displayed partially off the screen, or hidden altogether, by specifying device-unit positions that do not leave enough room for the calculated size of the child. Each part of the bounding structure is interpreted according to the value that controls it. A given rectangle might, for example, have an X-coordinate that is in device units, a Y-coordinate that is in proportional units, a height that is in proportional units, and a width that is in device units, or any other combination of device and proportional units. Rectangles that, when interpreted by using the current set on the child, represent bounding boxes that are partially or wholly off-screen—for example, by having a width that is larger than the screen width—may give unexpected results.
