cmd = new SqlCommand(Query, cs);
try

//set path of the Local report
ReportViewer1.LocalReport.ReportPath = Server.MapPath("~/DistOfficer/Report.rdlc");
//creating object of DataSet dsEmployee and filling the DataSet using SQLDataAdapter
SqlDataAdapter adapt = new SqlDataAdapter(Query.ToString(), cs);
DataSet ds = new DataSet();
adapt.Fill(ds, "dsEmployeey");
//Providing DataSource for the Report
ReportDataSource rds = new ReportDataSource("dsEmployee", ds.Tables[0]);
ReportViewer1.LocalReport.DataSources.Clear();
//Add ReportDataSource
ReportViewer1.LocalReport.DataSources.Add(rds);
}
