Assign a number to all cells in the front panel

I have several rows arranged like a table:

Screen Shot 2018-03-07 at 4.43.14 PM.png

The leftmost column displays the scroll number for each row. I want to allow the user to assign a number to all the cells in this column (so that all rows are scrolled to the same position) by entering this number only once, while leaving the option to scroll an individual row independently. What kind of item can I add to the front panel to accomplish this? Thank you.

There is no front panel item that does this out-of-the-box.

 

You need to handle value change events of e.g. a numeric control. If it changes, set the array's Index Values with a property node.

 

This will effectively set the indices of all arrays when the numeric changes. It will still allow changing the Index Values manually of each individual array.

 

Note that the numeric can also be a scrollbar.
