Hello.

How to check data existing in the ChildReport from the main report via the
RAP ?
Here is an example.

procedure DetailBeforePrint;;
begin
ppSubReport.SkipWhenNoRecords:=False;
if ppSubReport.IsEmpty then
Label1.Caption:='SubReport is empty'; ------???
end;

    - for a master/detail linking relationship, you can use the Linking dialog
    from the Data workspace to specify that you want to include master records
    in which no corresponding detail exists.

    - the Report and ChildReport classes have a NoDataBehaviors property that
    can be used to control what happens when the data is empty. Access the
    workspace the subreport and then use the object inspector to set the child
    report NoDataBehaviors. Use ndMessageOnPage value to display a message on
    the empty page. See the RBuilder.hlp for details.
