How to dynamic change the appearance of donzen of control of the same kind?

[Ralph_Zhou]

I want to change the appearance of a donzen of LED control in the panel by
program. How to realize it through a for loop without explicit change the
value of every control?

You may create a control reference for each LED and collect all references in an array.
Feed a for loop with this array and use property nodes to change value and appearance of all LEDs.

Pincanter,

COuld you also typedef the control and then make a change to one of them instead of all?...or can typedefs not be changed in runtime?

[pincpanter]

You can do the same with custom controls, too.
If I correctly remember, there are some limitation with strictly typed controls when you try to change things like colors and other appearance properties.
Values can always be changed, though.
