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.


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


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

The following example shows how to use the VerticalOffset property to cause a ContextMenu to open at a specified location in relation to its button parent.
