How to multiple output with Grid?

[lwei]

Hello!

I am working on an user select project.

I have a button and two grids.

The project function is to select users from the first Grid,

and after clicking on the button, the user's name output to the other Grid.

The problem is:

I can select multiple users but can only output one user.

How can I make it possible to output two or more users?

The output should be an Infotable with the DataShape which is the same as the first Grid, or a new DataShape which contains at least user's name. Then the service will read the infos from the input (which is also an Infotable I suppose), creates and add rows to a new Infotable as ouput.
