Description

DropDownCount is an Integer property which specifies the maximum number of values from Items that can be displayed in the drop-down list for the control. Setting a new value for the property causes the widgetset class to be notified using its SetDropDownCount method when a handle has been allocated for the control.

DropDownCount is used (along with the item count and ItemHeight) in the AdjustDropDown method to set the minimum dimensions for the drop-down list.

The default value for the property is 8.
