C# grouping / sorting Crystal Reports at runtime

[StevenK]

I am trying to set the grouping / sorting fields at run-time from C#.NET against a Crystal Report.
I'm using the code as provided in the help files using syntax like :
FieldDefinition FieldDef = new FieldDefinition();
FieldDef = Report.Database.Tables[0].Fields["FieldName"];
Report.DataDefinition.Groups[0].ConditionField = FieldDef;

I have the appropriate 'using' set up (for CrystalDecisions.CrystalReports.Engine.FieldDefinition.FieldDefinition()).

When I attempt to compile this code I am presented with a build error suggesting that :
'CrystalDecisions.CrystalReports.Engine.FieldDefinition.FieldDefinition()' is inaccessible due to its protection level'.

I've followed / copied the code sample as suggested within the help files.
Where have I gone wrong / what am I missing ?

Any pointers / help would be appreciated.

Thanks in advance.
Steve

I got the same error. But if would compile if I did not make a Field Definition. If I just used one line like:

cr.DataDefinition.Groups[0].ConditionField = cr.Database.Tables[0].Fields[3];

I'm now in the same boat as yourself.
However my report I'm making use of does not already have a Group set up - I need to be able to add (and set the Group Field) in one hit ?
Can this be done ?
Thanks again
Steve

You cannot add groups on the fly in Crystal Reports 8.5. You can in Crystal Reports 9, but the end user will have to buy a license.
