I have a WinForm with ReportViewer control and I need to pass some data
to the report I created. It's just few variables, not data from db.

How can I pass my custom object to my report ?

I think I'm looking for something like :

this.reportViewer1.RefreshReport(myObject);
or
this.reportViewer1.PassObject(myObject);
or whatever,
so I can somehow use this object in rdlc file .

What type of object? Can it be added as a data source? Perhaps you can just pass values from your object as parameters?

i think i got it :
            List<ReportParameter> paramList=new List<ReportParameter>();
            paramList.Add(new ReportParameter("TestPass", "10"));
            this.reportViewer1.ServerReport.SetParameters(paramList);
            this.reportViewer1.RefreshReport();  

but now how do I access these parameters in rdlc file ?

First add your parameters to the report. Click Reports from the file menu, then report parameters.
Next from your form with the report, dim an array for the parameters you wish to pass

        Dim parItems(2) As ReportParameter
        parItems(0) = New ReportParameter("Parameter1", MyObject.FirstName)
        parItems(1) = New ReportParameter("Parameter2", MyObject.LastName)
        parItems(2) = New ReportParameter("Parameter3", MyObject.Address)

Then before refreshing the report add your parameters

Me.ctlReportViewer.LocalReport.SetParameters(parItems)
