<ContextMenu HorizontalOffset="50" VerticalOffset="50" HasDropShadow="false">

XAML Values

double Double

String representation of a Double value. This is interpreted as a device-independent unit (1/96th inch) measurement. Strings need not explicitly include decimal points. For instance a value of 1 is acceptable.

The same Double range restrictions as mentioned in the Property Value section apply.

qualifiedDouble A double value as described above, followed by one of the following unit declaration strings: px, in, cm, pt.

px (default) is device-independent units (1/96th inch per unit)

in is inches; 1in==96px

cm is centimeters; 1cm==(96/2.54) px

pt is points; 1pt==(96/72) px

Note In many cases a double may be set to Auto but a ContextMenu will not appear if the offsets are set to Auto.
