How to set Delay and Interval of WPF RepeatButton?

The Delay and Interval properties make a RepeatButton different than a normal button.

A RepeatButton is a button that fires Click events repeatedly when it is pressed and held. The rate and aspects of repeating are determined by the Delay and Interval properties that the control exposes.

The code snippet in Listing 3 sets the Delay and Interval properties.

<RepeatButton Margin="10,10,0,0" VerticalAlignment="Top"

              HorizontalAlignment="Left"                      

              Name="GrowButton"  Width="80" Height="30"

              Delay="500" Interval="100"

              >

    Grow

</RepeatButton>
