Dimmed buttons in the array

[robinwei@df.com]

Hi,

I encountered a strange behavior on some buttons(control) in an array and I just can't figure out how to resolve this. If you look at the picture I attached below, you can see some buttons are dimmed in the array. It looks like this whenever I open up the VI and no matter how I initialized the button while they are not dimmed, they always go back to dimmed if I reopen it. It doesn't affect the functionality, but it is super annoying and it looks very unprofessional. Thanks for your advice in advanced.

The number of elements in the array is tied to its "default value". If you want to set a new default value, you can select the control, then click edit >> make selected values default.

Those buttons are dimmed because those array elements are empty.

1. Put the desired default value into the array.
2. Right-click on the array (make sure it's on the array, not on one of the elements).
3. Select: Data Operations -> Make Current Value Default.

Thanks Greg for your suggestion. I did that for like 10 times, but it didn't work. 🙂
