RadRepeatButton provides press-and-hold functionality. While the mouse button is pressed down, the ButtonClick event fires at a pre-determined interval. RadRepeatButton is an ideal UI element for allowing users to control an increasing or decreasing value, such as volume or brightness. To learn how to use the RadRepeatButton, see Working with the Telerik RadRepeatButton. As with all RadControls, RadRepeatButton is themable and also has a set of predefined themes.
