 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  Auto  Enables autosizing behavior. See Remarks. 

Property Value

A double that represents the height that is retrieved or the height to set. The default value as defined to the property system is a calculated value based on taking a one-third fraction of the system max screen height parameters, but this default is potentially overridden by various control templates.

Identifier Field

MaxDropDownHeightProperty

Metadata Flags

None

Auto sizing is not the default, and will result in the drop down size potentially exceeding the available size in the parent element. This is not typically desirable.

The following example shows how to use the MaxDropDownHeight property to specify the height of the ComboBox control's drop-down.

<Setter Property = "MaxDropDownHeight" Value="30"/>
