I'm doing my 2nd ever Crystal Report using the Visual Studio 2008 version.  The report has 2 different types of detail lines, each with their own corresponding heading.  I made two groups, two details and set conditional logic to determine which one prints for each type of data.  This works great.  But I need 1 (and only 1) of the details to do a "Format with multiple columns" type display with 2 or 3 columns of the data fields in each row of the dataset for this particular detail.  I can't see a way to set "Format with multiple columns" for only 1 of the detail lines.  I'm thinking there must be some way to do what I want (perhaps an array?) but I can't find any examples on the web or in the books I have.  FYI I tried doing this task with a Sub Report for the multi column detail but I ran into problems with the headings, pagination, and using multiple datasets so I abandoned that approach.  Could someone please offer some help?

I was thinking that there should be a way to capture each detail record before it printed.  I could keep a counter of what record number I was on.  If it was an odd number record I could populate two variables with the two fields from the current detail record.  If it was an even number record I could populate two other variables with the two fields from the current detail record, then print all 4 variables (with the appropriate formatting) as a detail line.  I could do this until the end of the group.  At the end of the group I'd check to see if I needed to print a last line because of an odd number of records.  I guess if I had more than one group (which I do) I could reset the "what record is it?" counter in the group header.   In other programming languages this would be pretty simple, but I have no idea how to manipulate the detail section of CR like this.  Is it doable?  With something like a "WhileReadingRecords"?  If so can you give me some how to?
