DropDownButtonDisplayMode Property (XamDateTimeEditor)

Specifies when to display the drop down button. Default is MouseOver.
Public Property DropDownButtonDisplayMode As DropDownButtonDisplayMode
public DropDownButtonDisplayMode DropDownButtonDisplayMode {get; set;}

The DropDownButtonDisplayMode determines when the drop down button should be displayed.

Note that the drop down button will always be displayed when the editor is in edit mode. Therefore if the IsAlwaysInEditMode is true, this property will be ignored and the button will always be displayed.

Note that the default value of the property is MouseOver however styles of some of the themes may explicitly set this property to some other value to ensure consistency with the default operating system behavior. For example, the default XamComboEditor style in "Aero" theme used in Windows Vista sets this property to Always.

The following example demonstrates handling the events that are invoked when the calendar dropdown is opened and closed.

For an overview of how to handle events in Visual Basic or Visual C#, see Event Handlers in Visual Basic and Visual C#. For specific information and code examples illustrating how to consume events in your application, see Consuming Events in the .NET Framework Developer's Guide.
