Data Rules - how to set a style for all columns in view and what is Multi Action Column?

I would like to set style Read Only for all columns in Data View based on condition. Is this doable in App-Studio Data Rules Wizard? (I don’t want to add column by column).

What is purpose of Multi Action Column? How this can be used? Any examples or at least explanation?

Use “DisableRow”:

I wrote in my original message that I want to set style based on condition. Your proposal is not allowing to use condition.

So add a condition? Those are there too.

Information to the people like me (working on Saturdays and blind or bit tired [pick correct option]):
In “Select Action” drop down you should select “Disable” option. Then “DisableRow” will be available.
