Hi Andre,
thank you very much for your answer. I tried your code but it
doesn't do the job. It is like pushing the column header of the
datagrid two times (first the number one and the the date one).
Bonjour Marcello,
Sorry, I had read your question too quickly. Did not noticed you would
like to start from a click on the header (so went as if it would be
from a button)
I am quite sure what you want is possible; (sure also that Trevor will
help on that ;-))
Excited by the problem, I am trying to find a solution but up to now
without any success. I don't find out how to get the name of the
clicked column' header (except in the sort command itself)
the dgColumn of the target returns the name but not when clicking on
the header (only when clicking on a a row in a column.
Looking forward getting a solution
Best regards from Grenoble
André
My data come from a sql base so I can (as Steven said) make the
query do the work of the multiple sorting before loading into the
datagrid but I'm scared about performances when it comes to manage
hundreds of thousands of data. In this scenario I need to retrieve
data from the sql base and then populate the datagrid every time I
need to sort the rows without the data I already have in the
datagrid. This means more traffic over the network and multiple
populations of the datagrid...
Best regards
Marcello

I think yes! Assuming for instance you want the dates sorted from
the oldest down to the more recent
and then, for each date, the numbers should be sorted from the
smaller down to the greater
you should sort the numbers column first then the dates' column.
Something like that:
on mouseUp
##setting the sort type value for each column
set the dgColumnSortType["date"] of grp "datagrid 1" to "system
dateTime"
set the dgColumnSortType["number"] of grp "datagrid 1" to "numeric"
set the dgColumnSortType["title"] of grp "datagrid 1" to text
## making sure the two columns will have the same sortDirection if
necessary
set the dgColumnSortDirection["date"] of grp "datagrid 1" to
"ascending"
set the dgColumnSortDirection["number"] of grp "datagrid 1" to
"ascending"
## sort "number" first then "date"
dispatch "sortByColumn" to grp "datagrid 1" with "number"
dispatch "sortByColumn" to grp "datagrid 1" with "date"
end mouseUp
