Examples
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"/>
Remarks
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.

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
Auto
Enables autosizing behavior. See Remarks.
