Hi Andre,
thanks again for your kind interest in solving this tricky issue.
I tried your code but the result is the same. It automates the
process of clicking on two column headers.
What I would like to accomplish is different. I would like to sort
with more than one criteria my datagrid rows when I click the header
of the column date. Here there is an example of the scenario I would
like to accomplish (look at the first two rows in both examples:
Number Date Customer
1 01/01/2010 aaaaaa
2 01/01/2010 bbbbbb
3 01/01/2010 cccccccc
4 02/01/2010 aaaaaaa
5 02/01/2010 bbbbbbb
I would like that when I sort by date, the data can also by sorted
by (for example) customer (On the same date, the data must sorted
alfabetically by Customer)
With your code (or with the default sorting code of datagrid) the
result is this:
Number Date Customer
2 01/01/2010 bbbbbb
1 01/01/2010 aaaaaaa
3 01/01/2010 cccccccc
4 02/01/2010 aaaaaaa
5 02/01/2010 bbbbbbb
I can accomplish what I need querying the database with something
like:
select number, date, customer from invoices order by date asc,
customer asc
I think that, apart from the sql query, there are two chances:
1. The datagrid code can itself manage muti criteria sorting (maybe
here Trevor can give us a hint)
2. We have to process the array of the datagrid, sorting with
multicriteria and then populate again the datagrid with the new array.
Any idea?
Bonsoir Marcello,
Sorry again, I have been rather "slow" to understand ;-))
I think that my first proposal was what you wanted except that I did
it from a button (a mouseUp handler) while you wanted to it from a
click on the header (which I proposed in my second solution, but then,
I misunterpreted your sentence "I would like to sort the lines of the
invoice datagrid first by invoice date and then by number"
Actually, to do a multi-criteria sorting (here two criteria) one must
sort firstly by the second criteria, then by the first one. So that
one gets the names in alphabetical order inside each date.
So a mixt of my two proposal seems to do the trick ( In fact it
suffices to inverse the order of the two "dispatch" lines in the last
script I send you (as they were in the first proposal); hence:
---------------------------------------
local hcColumn,theColumn
-------
on mouseDown
## just to be sure the sort types are right
set the dgColumnSortType["date"] of grp "datagrid 1" to "system
dateTime"
set the dgColumnSortType["name"] of grp "datagrid 1" to text
## to impose the sorting direction of "name"
set the dgColumnSortDirection["name"] of grp "datagrid 1" to
"ascending"
## sorting by 2 criteria:alphabetical order of customers inside each
date
put the dgHeaderControl of the mouseControl into hcColumn
if hcColumn is not empty then
put the dgColumn of the target into theColumn
if theColumn is "date" then
dispatch "sortByColumn" to the target with "name" ## second
criterium
--wait 1 sec
dispatch "sortByColumn" to the target with "date" ## first
criterium
end if
end if
end mouseDown
Is this working as you are expecting (seems OK here in my trials)
(cross my fingers ;-o)))
Best regards from Grenoble
André
