I need to sort the lines of a datagrid with more than one criteria.
For instance:
The datagrid represents invoices with these columns:
- invoice date
- invoice number
- invoice title
When I click on the invoice date header I would like to sort the
lines of the invoice datagrid first by invoice date and then by
number.
Begin by reading this lesson:
http://lessons.runrev.com/spaces/lessons/manuals/datagrid/lessons/7330-How-Do-I-Customize-Column-Sorting-
In the switch statement you create for "invoice date" just perform the
sort you need using SortDataByKey (http://lessons.runrev.com/spaces/lessons/manuals/datagrid/lessons/7334-How-Do-I-Sort-Records-By-A-Specific-Key-s-Values-
):
on SortDataGridColumn pColumn
switch pColumn
case "invoice date"
SortDataByKey "invoice date", ...
SortDataByKey "invoice number", ...
HiliteAndStoreSortByColumn pColumn
break
default
pass SortDataGridColumn
end switch
end SortDataGridColumn
Untested but it should work.
