Changing a grouping using code (1 Viewer)

[Funkyaccess]

Hi,

Is there anyway I can change my grouping on a specific field either by changing the field or changing the criteria eg a date field group by day/week/month/year

I have to date fields that I would like to use. If I can do this with code what is the best event to use to trigger this.

Or does it mean I should create another report with using the other date field.

I do this type of thing, referring back to the form used to open the report:

Private Sub Report_Open(Cancel As Integer)
  Select Case Forms!frmReports.fraGrouping
    Case 1 'group on car type
      Me.GroupLevel(0).ControlSource = "CarType"
      Me.txtGroup.ControlSource = "CarDesc"
    Case 2 'group on company
      Me.GroupLevel(0).ControlSource = "Company"
      Me.txtGroup.ControlSource = "Company"
    Case 3 'sort on date/time, no grouping
      Me.GroupLevel(0).ControlSource = "DispDateTime"
      Me.txtGroup.ControlSource = "DispDateTime"
      Me.GroupHeader0.Visible = False
  End Select
End Sub

Thanks I'll give that a try. Does that cover grouping within a time frame i.e day/week/month/year or what ever you want a date field to be grouped by?

I think I misunderstood the goal. That changes which field a report groups on, but doesn't change the data itself. If you're saying that you might want the report where it groups/sums data by week one time, by month the next, that would be different. Is that what you meant? Like a user selectable grouping period?

Yes that correct. Though you first reply was helpful as I can now change the column that needs to be group by. I just need to change the period using a radio button option group.

anybody able to help?

Sorry, lost track of this thread. The only ways that come to mind would either involve changing the SQL of the underlying query, or perhaps having day/week/month/year fields in the query and grouping on the appropriate one. If you can post a sample db with enough test data to illustrate the problem, I'll try to play with it.

just looked at the Access help with GroupLevel and it mentioned other things of which GroupOn seems to be the one I'm after will let you know if I run into difficulties.
