I have several extremely similar datawindows that I have to maintain that go
against the same table. Recently, I had to add a column to that table, and
also add the column to ALL of these datawindows that go against this table.

column is linked to the column I selected, HOWEVER, when I...to Calculated Columns, then to update another column in same table in ADO.NET

My first solution signs where:
create a computed field (small_function_result) that takes the value from
the preceding row:
small(value, value, cf_getrow for all); where cf_getrow is a computed field
create a computed field (Diff) that computes the difference:
My results should look like this:

You have to use a custom template and lay the table out the way you want, either dropping controls in the template or creating a custom ITemplate that takes care of it for you.

Please - Can anyone suggest the best way to display a joined dataset with 4 read-only columns, 4 editable columns and a checkbox column?
The content for this display currently has < 100 rows - but could approach 1000 in the future.
I currently have this setup with a Datagrid (working) - but I would like to be able to edit the 4 columns of ALL rows in the displayed list instead of one row at a time as the Datagrid allows.
After editing, I use an update function to traverse the modified list/table and save all values that have the Checkbox clicked.

to write the file column after column. Is there a file writing mode
If not, I guess, I will have to write the matrix row by row and then

share some skeleton of code for something like this would be great.
