Button Type property
This is where you can specify certain aspects of button behavior. This property can have one of three possible values:
The Standard button type (the default) has no special characteristics.
If the Button Type property is set to SplitButton, a Menu Page property becomes active’. This Menu Page property contains a menu definition that is displayed when the area with the arrow is clicked.
If the Button Type property is set to CommandLink, a Note property becomes active. This Note property contains the note that is displayed under the label.
These button types can only be used on Vista and Windows 7 machines. On other machines a gray area is displayed.
