Gets or sets the x-coordinate value of a Rect.
The width of the Rect, in pixels.
This property is read/write. The default value is 0.
Property values for a Rect and an object for Rect are not available for all cases where Rect is used as a property type. For more information, see the "Remarks" section in the Rect reference topic.
The properties of a Rect do not have a XAML usage, because there is no way to create a Rect in XAML as an object element. Instead, you always specify a Rect as a string that is either provided as a XAML attribute value or set to a property value in script. Each of these cases is supported by a type conversion behavior. If the particular property that is being set can return a Rect as an object to script, the value that is provided in the original string can be retrieved as the Width value of that Rect object.
