Switch and LED Array Controls
Use the Measurement Studio switch and LED array controls as an array of
Boolean controls on a Windows Forms user interface. You typically use a
switch array control, as shown in Figure2-10, to contro l ports of a digital
line or values of an array. You typically use an LED array control, also
shown in Figure2-10, to visualize ports of a digital li ne or values of an
array.
Figure 2-10. Windows Forms Switch and LED Array Controls
With the switch and LED array controls and the classes that interface with
the controls, you can perform the following operations:
• Set values by passing an array of data.
• Modify the number of controls displayed based on the length of the
specified values.
• Receive notification before or after the state of the control changes.
• Configure how the control behaves when you click it with the mouse
or press the spacebar when the control has focus.
• Configure the appearance of the control.
• Make the control background transparent.
• Configure the LED controls to blink while they are on or off and
configure the rate at which the LED controls blink.
