Hi Beat,
Thanks. I'm glad you like it.
I have studied the manual and the list, so I hope my questions have
not been asked before :
1. Is it possible to print the content (including headers) of a
Datagrid like printing a field. I mean so that the layout of the
Datagrid is kept. This would be absolutely great.
Of course I could 'Print card', but the quality is much less than
printing text from a field. I am afraid it won't yet be possible, as
it is not mentioned in the manual or on the list.
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.
2. How do I set the number of columns by script?
Set the "columns" property. It is listed on the properties page.

3. Is it possible to drag a complete line in a DataGrid to a new
position (custom hand sorting)?
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.
4. How can I lock one column for editing, leaving the others free to
be edited? dgProps["allow editing"] seems to be a global prop.
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.
5. Is it possible for a piece of text to overflow into the next cell
if that cell is empty. If so, how do I do that?
There is no built-in way of doing this.
6. How do I 'open up' a cell by script for the user to immediately
type into it.
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,
pIndex
I noticed that the Datagrid group stays 'grouped', also if I choose
the inverse of 'select grouped'. While ordinary groups yield their
parts, not so the Datagrid.
I am wondering if the only reason is, that the user will not mess up
the coordinates of the parts of the group, or is there another
deeper reason behind?
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.
much thanks for this great piece of work,
You are welcome.
