Accessing and Customizing Elements

Accessing and customizing elements can be performed either at design time, or at run time. Before proceeding with this topic, it is recommended to get familiar with the visual structure of the RadDropDownButton.

Design time

You can access and modify the style for different elements in RadDropDownButton by using the Element hierarchy editor. It can be accessed by selecting the Edit UI Elements item from the Smart Tag.
