Property Value

Type	Description
CheckedListBoxControl	A CheckedListBoxControl embedded in the control’s dropdown.

Remarks

The recommended approach to customizing settings of the embedded CheckedListBoxControl is using the properties and events provided by the CheckedComboBoxEdit.Properties object. Although direct customization of the InternalListBox object is possible, this capability should only be employed in advanced cases that are not covered by the settings and events available from the CheckedComboBoxEdit.Properties object.

The InternalListBox property is initialized when the dropdown window is opened for the first time. The object is not destroyed on closing the dropdown window. If the dropdown window has not been invoked, the InternalListBox property returns null.

To respond to showing a dropdown window, you can handle the RepositoryItemPopupBase.Popup event.
