report

You would need to design the report using a dataset first and then populate it with datatable at runtime

http://msdn.microsoft.com/en-us/library/ms252094(v=vs.80).aspx

Create the report with a ghost dataset with the fields you want Then do somehitng like

StrSql = StrSql + "Señect .........")
ReportViewer1.Reset()
ReportViewer1.LocalReport.ReportEmbeddedResource = "WindowsApplication1.ReportName.rdlc"
Conn.Open()
adap1 = New System.Data.SqlClient.SqlDataAdapter(StrSql, Conn)
ds = New System.Data.DataSet()
adap1.Fill(ds, "Wherever")
Conn.Close()
ReportViewer1.LocalReport.DataSources.Clear()
Dim rs As Microsoft.Reporting.WinForms.ReportDataSource = Nothing
rs = New Microsoft.Reporting.WinForms.ReportDataSource("RerortDatasetGhostName", ds.Tables(0))
ReportViewer1.LocalReport.DataSources.Add(rs)
ReportViewer1.AutoSize = True
Me.ReportViewer1.RefreshReport()

Hope this help
