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.
Type: System.Double The vertical distance between the target origin and the popup alignment point. For information about the target origin and popup alignment point, see Popup Placement Behavior. The default is 0.
