Dim query As String = "SELECT std_Info.std_ID,std_Info.std_Name_ar FROM std_Info"
        Dim reportDataSet As New DataSet
        Dim sqlAD As New SqlDataAdapter(query, conn)
        sqlAD.Fill(reportDataSet)
        Dim rds As New ReportDataSource("DataSet1",reportDataSet.Tables(0).TableName().ToString())

        Me.ReportViewer1.ProcessingMode = ProcessingMode.Local
        Me.ReportViewer1.LocalReport.LoadReportDefinition(New StreamReader("FULL PATH\test.rdl"))
        ReportViewer1.LocalReport.ReportPath = "FULL PATH\test.rdl"
        ReportViewer1.LocalReport.DataSources.Clear()
        ReportViewer1.LocalReport.DataSources.Add(rds)
        Me.ReportViewer1.RefreshReport()

so the problem is .. only the design of my report appears BUT NO DATA :(
