        DataTable dc = getsub(txtprop.Text);
        prgreport.Visible = true;
        ReportDataSource ds = new ReportDataSource("byproGRdataset", dts);
        ReportDataSource dss = new ReportDataSource("propM", dc);
        prgreport.LocalReport.DataSources.Add(ds);
        prgreport.LocalReport.DataSources.Add(dss);
        //path
        prgreport.LocalReport.ReportPath = "marksbyprGR.rdlc";

    private DataTable getdata(string valu)
    {
        DataTable dt = new DataTable();

        using (OleDbConnection con = new OleDbConnection(constring))
        {
            OleDbCommand comm = new OleDbCommand("SELECT DISTINCTROW [Mark],[TMNumber],[TMCountry],[Class],[RenDate],[Status],[Comments],[GoodsServices],[logo] FROM Mark WHERE [Proprietor] like '%'+@SearchText+'%' GROUP BY [Mark],[TMNumber],[TMCountry],[Class],[Comments],[RenDate],[Status],[GoodsServices],[logo] ORDER BY [Mark],[Class],[TMCountry]", con);
            comm.CommandType = CommandType.Text;
            comm.Parameters.AddWithValue("@SearchText", valu);
            OleDbDataAdapter adp = new OleDbDataAdapter(comm);

            adp.Fill(dt);
