Create Report programmatically

[IMF]

Hello,

 

I need to create a report programmatically and watch this report in a report viewer when i push a button for print this. I have read information but i can't resolve it. This is my code:

 

 

protected void Page_Load(object sender, EventArgs e)
   {
       doReport();
   }

   private void doReport()
   {
       DataTable table = new DataTable();
       table.Columns.Add("Col1", typeof(string));
       table.Columns.Add("Col2", typeof(string));
       table.Columns.Add("Col3", typeof(string));
       table.Columns.Add("Col4", typeof(string));

       List<datos> datosList = new List<datos>();
       datosList.Add(new datos { dato1 = " lala", dato2 = "lele", dato3 = "lili", dato4 = "lolo" });
       datosList.Add(new datos { dato1 = " lala", dato2 = "lele", dato3 = "lili", dato4 = "lolo" });
       datosList.Add(new datos { dato1 = " lala", dato2 = "lele", dato3 = "lili", dato4 = "lolo" });
       datosList.Add(new datos { dato1 = " lala", dato2 = "lele", dato3 = "lili", dato4 = "lolo" });

       for (int i = 0; i < datosList.Count; i++)
       {
           string dato1 = datosList[i].dato1;
           string dato2 = datosList[i].dato2;
           string dato3 = datosList[i].dato3;
           string dato4 = datosList[i].dato4;
           table.Rows.Add(dato1, dato2, dato3, dato4);
       }

       Telerik.Reporting.ObjectDataSource objectDataSource = new Telerik.Reporting.ObjectDataSource();
       objectDataSource.DataSource = table;
       objectDataSource.CalculatedFields.Add(new Telerik.Reporting.CalculatedField("FullName", typeof(string), "=Fields.PagePath + ' ' + Fields.Pageviews")); // Adding a sample calculated field.


       Telerik.Reporting.Report report = new Telerik.Reporting.Report();
       report.Name = "prueba";
       report.DocumentName = "prueba";
       report.DataSource = objectDataSource;

       Telerik.Reporting.InstanceReportSource reportSource = new Telerik.Reporting.InstanceReportSource();
       reportSource.ReportDocument = report;

       ReportViewer1.ReportSource = reportSource;

       ReportViewer1.RefreshReport();
   }

   public class datos
   {
       public datos()
       {}

       public string dato1 ;
       public string dato2 ;
       public string dato3 ;
       public string dato4 ;
   }

 

Any idea? Thanks

Hi IMF,

In your example there is a new blank Telerik.Reporting.Report instance bound to custom data. Telerik reports are templates which must contain fields from the schema of the assigned data object.

For more details, please check a similar discussion in this forum thread (my first two posts).
