I have a grid that returns fields from a SQL Database.
I've setup my grid to not display a couple of the fields by setting their "Visible" property to False in the Column/Behavior section of the Property Builder.

I've set the Edit mode to be PopUp so that the editing of a record happens in a PopUp window.

Everthing works fine except that the PopUp window displays the fields that have their "Visible" property set to False.

Is there a specific place to set propertys for which fields to display in the PopUp window?
Or is it working as designed and I need to find a different solution?

Thanks in advance for any help,
Mike T.

That worked perfectly. 
Thank you very much for taking time to help me.
