Hi,
Is there a way that I can get the same sort of output as when you create a
relationship between two tables, but with only one table?
With a dataset containing two (or more) tables that has a data relation
added, you get a resultant output (say a datagrid) that groups by the column
detailed in the relationship. When the datagrid is displayed it shows each
parent record (row) with a '+' next to it. When selected you can then
display the related child records.
I have a single table with multiple records. Let's say one field is name.
There may be multiple records for each person who is displayed in the name
field. Instead of doing a simple sort and showing all records at the same
time, I would like to have the '+', and only show the persons name once. I
could then expand that record to show all for that person.
Is this possible?
I am using VB.Net, windows display (not IE), and sql server.
Hope there is an answer out there............even if it is NO ;-)
Rgds, PhilPhil,
use
SELECT DISTINCT name FROM table
for the first DataTable and
SELECT name, other_cols_needed FROM table
for the second DataTable.
Then add a DataRelation on the name column.

Thanks for the response but I only have ONE table, as stated. If I had two
tables then it wouldn't be a problem for me. Can it be done with one table?
Cheers, Phil

You can use two selects to fill two DataTable objects from a single SQL
table.
