Switch and LED Controls
Use the Measurement Studio switch and LED controls as Boolean controls
in an ASP.NET Web application. You typically use a switch control to
receive and control Boolean input in an ASP.NET Web application. You
typically use an LED control to indicate a Boolean value on an ASP.NET
Web application. The switch and LED controls are shown in Figure 2-19.

With the switch and LED controls and the classes that interface with the
controls, you can perform the following operations:
• Receive notification before or after the state of the control changes.
• Specify the image format of the control as BMP, GIF, JPEG, or PNG.
• Configure the appearance of the control.
• Configure the LED control to blink while it is on or off and configure
the rate at which the LED control blinks.
