Hello everyone,

I have written a student report card application but I can only print a report at a time. I want to be able to print all students report at a go.

I will be glad if anybody can help. thank you!

below is codes I tried and it only shows the detail of the last student in the table.

try
           {
               for (int i = 0; i < listBox1.Items.Count - 1; i++)
               {
                   string myitems = listBox1.Items[i].ToString();

                   // TODO: This line of code loads data into the 'DataSet1.Investment' table. You can move, or remove it, as needed.
                   this.InvestmentTableAdapter.Fill(this.DataSet1.Investment, myitems.ToString());
                   // TODO: This line of code loads data into the 'DataSet1.DataTable1' table. You can move, or remove it, as needed.
                   this.DataTable1TableAdapter.Fill(this.DataSet1.DataTable1);
                   // TODO: This line of code loads data into the 'DataSet1.prcindividual' table. You can move, or remove it, as needed.
                   this.prcindividualTableAdapter.Fill(this.DataSet1.prcindividual, myitems.ToString(), "2015");
                   // TODO: This line of code loads data into the 'DataSet1.prcindividualcal' table. You can move, or remove it, as needed.
                   this.prcindividualcalTableAdapter.Fill(this.DataSet1.prcindividualcal, myitems.ToString());


               }
               this.reportViewer1.RefreshReport();

           }
           catch (Exception ex)
           {
               MessageBox.Show(ex.Message);
           }
