My report isn't work properly. It doesn't show any row of data which is retrieved from database. So I try to create a datagridview for test the result of query command (.rldc report and datagridview use the same datasouce) and it works fine. Only the .rdlc report that is not working because it shows header only. Here is my codes and a picture of running result.

VB

sqlcmd = "select * from tb_employee"
cmd = New OleDbCommand(sqlcmd, cn)
dr = cmd.ExecuteReader()
dt.Load(dr)
gvtest.DataSource = dt
datasetReport.Tables(0).Load(dr)
dr.Close()
cn.Close()
       rds.Name = "dsReportGroupByProject_dtReport"
rds.Value = datasetReport.Tables(0)
Me.ReportViewer1.LocalReport.DataSources.Add(rds)
Dim rpt(2) As ReportParameter
rpt(0) = New ReportParameter("monthStart",ddlmonth.SelectedItem.ToString)
rpt(1) = New ReportParameter("monthStop", ddlmonth.SelectedItem.ToString)
rpt(2) = New ReportParameter("quot;year", ddlyear.SelectedItem.ToString)
Me.ReportViewer1.LocalReport.SetParameters(rpt)
Me.ReportViewer1.RefreshReport()

Now,I have already fix it by improve that code to this:

VB

sqlcmd = "select * from tb_employee"
        cmd = New OleDbCommand(sqlcmd, cn)
        dr = cmd.ExecuteReader()
        dt.Load(dr)


        datasetReport.Tables(0).Load(dr)
        dr.Close()
        cn.Close()
        'ReportViewer1.LocalReport.ReportEmbeddedResource = "QSBGPayRoll.ReportEmps.rdlc"
        rds.Name = "dsReportGroupByProject_dtReport"
        'rds.Name = "DataSetReport_dt1"
        rds.Value = dt 'datasetReport.Tables(0)
        gvtest.DataSource = datasetReport.Tables(0)
        ReportViewer1.LocalReport.DataSources.Clear()
        Me.ReportViewer1.LocalReport.DataSources.Add(rds)
        Dim rpt(2) As ReportParameter
        rpt(0) = New ReportParameter("monthStart", ddlmonth.SelectedItem.ToString)
        rpt(1) = New ReportParameter("monthStop", ddlmonth.SelectedItem.ToString)
        rpt(2) = New ReportParameter("year", ddlyear.SelectedItem.ToString)
        Me.ReportViewer1.LocalReport.SetParameters(rpt)
        Me.ReportViewer1.RefreshReport()

Thank you for myself and my effort.
