The column's width, expressed as a floating-point value for a pixel count. Typically this is specified as an integer, although interpolation of floating-point values is supported by grid layout.
A convention by which you can size rows or columns to take the remaining available space in a Grid. A star sizing always includes the asterisk character (*), and optionally precedes the asterisk with an integer value that specifies a weighted factor versus other possible star sizings (for example, 3*). For more information about star sizing, see Grid.
The column's width, described by the literal Auto. For more information about Auto sizing, see Grid or GridLength.
If a child element is added to a column in a Grid, and the column has its Width property set to Auto, the child will be measured without restrictions. This behavior can prevent horizontal scroll bars from displaying if a ScrollViewer is being used, as the child element is measured as unbounded. For purposes of display, the child is clipped instead of scrolled.
