Report in C#

I made a report in C# using Visual Studio 2010 Report1.rdlc. I put the control printDocument1 on the form, with properties DocumentName c: Report1.rdlc. I also put controls printPreviewControl1 and printPreviewDialog1 and in those two controls' properties I selected Document printDocument1. When I run it, a blank report comes up without a dialog, I don't know what else do I need to do to have the data and dialog showing...
