Hello everybody,
I have difficulties with a subreport.
The main report is displayed OK, but the subreport just says "The
subreport could not be shown".
If I set no dataset to the subreport, I can display the parameter
correctly in the subreport, so it is received OK, but not managed after
that.
I tried with a sample :
http://gotreportviewer.com/masterdetail/index.html
(the first one on the page, the one that has a subreport).
It displays the sample data OK, after that I add datasets with my data
(one for the main report —orders, and one for the subreport —orderdetails).
I set the datasets to the reports, set the fields and parameters, and
when launching I see that the main report just says "A data source
instance has not been supplied for the data source
'DataSetPoste_tabPoste'", whereas I verified that the tabPoste DataTable
in the DataSetPoste dataset returns the good data.
Could anyone give me any clue about how to instanciate a dataset, once
you know that it returns correct data ?
