reach from faceplate container

Hello, I have similar problem like this,

I want to reach from faceplate container where is in screen faceplate, to screen faceplate parameter.

I opened topic for this but I havent been getting any answer from anyone.

Maybe we can use dataset function. But I cannot tried it yet.

We can send a lot of parameter from screen to inside container via dataset function. But i don know that we send parameter from container to screen.
