I think you're better off with a custom component (perhaps implemented
as an HBox of List controls). A DataGrid does indeed intend to show
*rows* of data. You'll be fighting the component's basic design idea the
whole way if you start with a DataGrid.
You should also consider the user interface impact of such a component:
it's an intriguing approach to the problem and it could certainly work,
but it's easy to create a usability train wreck when getting too
adventurous in UI design. Make sure to test it with real users as much
as possible.

Hi, folks,
I am trying to do something weird with datagrid, which will be described
a
bit later. Please let me have your insights about if it is the right
direction or not.
I would like to have a table about 30 rows by 19 columns, which will
present
information about cars. Each column represents an attribute (e.g., mpg,
acceleration, price) of various cars, and each row (kind of) represent a
car
(e.g., civic, camry, accord, etc.). One thing strange about this table
is
that, all columns are sorted. It is different from the multi-sorting
feature
of AdvancedGrid. Let me show you an example.
Cars | MPG | Price
Accord | 10 mpg (of Civic) | $1 (of Camry)
Civic | 20 mpg (of Accord) | $2 (of Civic)
Camry | 30 mpg (of Camry) | $3 (of Accord)
Since all the columns (i.e., Cars, MPG, Price) are sorted, the rows are
messed up. The first row contains the information about Accord, the MPG
of
Civic, and the price of Camry. In this representation, a row doesn't
represent a specific car any more. So, what I am trying to do is when a
person move a mouse cursor on a cell of Accord, all the cells related
with
Accord will be highlighted. In this way, a user will find out which cell
belongs to Accord through highlights even though rows are messed up.
While implementing this, I found that the underlying data structure does
not
seem to be well matched with this user interface. Each row is treated as
the
same element of a collection. Drawing is done line by line. However, as
you
can see, a row in this strange datagrid represents attributes of
different
elements. Due to this, highlights cannot be drawn line by line. It will
highlights all over the places.
What do you think? Should I build one from scratch? Or, using DataGrid
will
be fine for this?
Regards,
Ji Soo Yi
