Question Local Report Parameter Loading Problem

[buraqenigma]

i want to pass some paramaters to a localreport in my project but i get the "The source of the report definition has not been specified" error message.

My Code :

Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles
Button1.Click Dim ds As New ReportDataSource("ds_rapordata") Dim rps(0) As ReportParameter 
frm_rapor_goster.ReportViewer1.Reset() ds.Value = dt_grid.DataSource 
frm_rapor_goster.ReportViewer1.LocalReport.DataSources.Clear() 
frm_rapor_goster.ReportViewer1.LocalReport.DataSources.Add(ds) rps.SetValue(NewReportParameter("rp_baslik", "Başlık"), 0) 
frm_rapor_goster.ReportViewer1.LocalReport.SetParameters(rps) 
frm_rapor_goster.ReportViewer1.LocalReport.ReportEmbeddedResource = "WF_PROJECT.rpr_ucuslar_milli.rdlc" 
frm_rapor_goster.MdiParent = Me.MdiParent 
frm_rapor_goster.Show() End Sub

Thanx from now.
