Reportviewer empty

[Fury]

Hello,

I'm using a reportviewer to print out an order.
Everything goes well if there is only one orderdetail.
If there is more than one the reportviewer shows nothing, i get an empty page.
When i debug it seems that de refresh is missed.
I use a typed dataset and when i try the query in the querybuilder everything seems fine...
Can someone help me?

Te problem is solved. The cause was that i got the OrderID repeating while i really didn't need it in the report so i removed it and it works fine now.
But i have a question or two about the design of the report.
Is it possible to make rounded rectangles?
And I have a field in the table that represents a boolean value.
But it shows True or False. Is it possible to show anything else than True or False like in a DatagridView?
