Display in grid selected option

Hello guys!

So...I have 3 SQL services that get a parameter as input. Let's say service1, service2 and service3

And I have a 4th service that returns a list with all the possible parameters, displayed in a grid. Let's say GetParameters

I would want to update all the 3 services (displayed each in a separate grid) when I click on an option from GetParameters.

How could I do that?

I tried binding with a session variable but that didn't show much success.

Any kind of resource or video or anything would help.

Thank you!

By the way, below is a screen shot with what I mean.
