This one is a grand example of why I have such warm and fuzzies about Crystal Reports:
Reference Part II from yesterday.
It is 2:58 on Tuesday. I've been dorking with this since Friday afternoon sometime. About 1/2 hour ago I pulled everything back in from Version Control for about the 4th time today.
I modified the existing subreport by pulling fields out of the element associated with the report, and miraculously got it to accept it.
I then went into the code behind and pulled the data from the REAL table, and that worked!
So what I had was data from the table I wanted it from, populated to a subreport with 2 of 4 fields showing.
I modified the xsd file again and added just one of the two remaining fields, but I could not get the Field Explorer to change.
I deleted the .cs for the .rpt file and shut down Visual Studio and restarted it. Since I (obviously) have no idea what makes this work or not, I did a rebuild all. I then went into the Field Explorer and lo and behold, it has changed!
It changed back to what it was 1/2 hour ago! .... sigh...
