DataGrid: How do you hide all images?

[donryan]

I've got a data grid that contains a "group" called btnDEL on the form template that is normally hidden. When the user "swipes" it is displayed (this works fine). However, I'm trying to issue a reset command to hide the object again on another action (click or touch). I know how to create a repeat loop to cycle through the rows, but how do I issue a command to force hide this specific "group" object? Can anyone help?
