How sort records in a subreport based on the selection in a combobox on a form

Is there a way to sort the records in the detail section of a subreport based on the selection in a combobox on a form.

There are three choices:  Category, Location , and Room.  Each of this is a field in the query which is the reports recordsource.

I don't know if some code in the onopen event of the report would work?

I would do the sorting (and filtering, if that is needed) in code running from a control that opens the report, such as the Report button on my New Style Main Menu sample database.  Create a saved query using the selected sort, and make that query the record source of the subreport.  Here is a link for the Access Archon article featuring this database:
and here is a screen shot of the main menu:

You'll have to do it in the OnOpen of the report.  Report's ignore any sorting in an underlying data source.  Set the OrderBy property, and the OrderOnLoad property to True.

Something like this worked OK for me...

Obviously there will be other ways to do this, ...but sometimes I just like to manipulate the sorting in the Report's recordsource

Note too that sorting is impacted by Groups as well - so if you're Grouping by FieldA but tell Access to Sort by FieldB, then your records would show on the form "sorted" for FieldA, and for each of those Groups, the records would then be "sorted" by FieldB.

I mistakenly accepted your suggestion before I realized that I could not download your example.  Could you report it for me please?

Could not download it, ...or could not open it...?

Note that I used the recordsource here.

What the other experts posted about using the OrderBy Property is the more used technique.
For whatever reason,  I was having trouble with Ordeby in a SubReport, (opened by a form)

So my old fallback is to just grab the Recordsouce and sort that instead.
What this meas is that you ever add a sort in the report itself, the recordsouce sort will be ignored (as Jim States)

Finally note that this may all change if your report includes grouping levels.

So play around with this and also play around with Ordeby.
again, I can think of about half a dozen approaches to this...
