NPopupCombo Class
In This Topic
Represents a control which may display a NPopup instance in a combo-box like manner. As it is completely generic you may build any configuration - create a NPopupCombo instance, specify its "Popup" property and the control is ready-to-use. When the drop-down button on the right is pressed, the popup will be displayed, aligned with the combo. You may explicitly override the placement by specifying "UseDefaultPlacement" property. The default alignment depends on the DropDownDirection property.
