No, there is not special printing feature built into the data grid. I
haven't printed data grid content myself so I don't have any
suggestions in this area.

Set the "columns" property. It is listed on the properties page.

There is undocumented drag reordering functionality in the data grid.
I haven't had time to finalize and test the APIs yet so it will remain
undocumented until I do so. If you want to dig around in the code you
can start by looking at the dgTrackDragDrop setProp.

You can customize the default column behavior to do this:
How Do I Override the Default Behavior For Rendering Data to a Cell?: <http://revolution.screenstepslive.com/spaces/revolution_tools/manuals/datagrid/lessons/4202-How-Do-I-Override-the-Default-Behavior-For-Rendering-Data-to-a-Cell-
Just modify the behavior in the mouseDoubleUp so that cell editing
only occurs if a particular column is clicked on.

There is no built-in way of doing this.

I still have to put together docs on field editing but I think
EditCell/EditCellOfIndex should do what you need.
dispatch "EditCell" to group "DataGrid 1" with pColumnName, pLineNo
dispatch "EditCellOfIndex" to group "DataGrid 1" with pColumnName,

In Rev 3.5 the selectGroupedControls property of a group determines
whether or not you can select group controls. This is a very important
feature for custom controls. Just set selectGroupedControls of the
data grid group to false if you want to inspect it.

You are welcome.
