I am facing sometimes the problems that my ideas do not get to work.

I have an application with several reports.
In a Webpage I use a GridView to show the report data triggered by a Button.
Since all reports have infact the same functionality: a generic class should be usable.
WebPage
- GridView
- Button
- Some selection item used as parameters for DB
Report
- DataTable with Records for GridView
- parameterArray
Data Access Layer
- Generic Report class -> internal. I have a public sealed that should be called by the business logic

C#
internal class SimpleReport
{
   internal string StoredProcedure {get; set;}
}

internal class OtherReport
{
   internal string StoredProcedure {get; set;}
}

internal class Report<T> where T : class
    {
        public event Action<DataTable> GeneratedReport;

        /// <summary>
        /// Generates the specified t.
        /// </summary>
        /// <param name="t">The t.</param>
        internal void Generate()
        {
            DataTable aTable = new DataTable();
            /// How to use property StoredProcedure from SimpleReport/OtherReport here?
            /// The class SimpleReport/OtherReport is in the 'T'
            if (GeneratedReport != null)
                GeneratedReport(aTable);

        }
    }

In the Generic class the T could be SimpleReport. In SimpleReport I have a DataTable property. T could also be WeeklySalesreport and has the same DataTable property (by name -> public DataTable Values;
How can I use the property Values in the Generic class based on the given event Action<datatable> GeneratedReport?

Furthermore each report class could have different set of parameters (they all have reportperiodID -int- common) How could I map them via the Generic class?

Or is my idea totally wrong?

What does it mean "to load a class"? "A generic class load a class"?

I can understand you can't understand my idea. It is hard to explain for me.
In fact I have a class for reports with properties. And when using the generic class (that is used for a class for a report) these properties should be used.

Even now, I have no idea. It needs detail.

We don't get your idea... ;(

C#
public class Cell
{
    private int cell_id;
    private string cell_name;
    private string cell_supervisor;
    private double cell_target;
    private double cell_routing_target, cell_attended_target, cell_lost_time_target, cell_unaccounted_time_target, cell_absence_target;
    private List<string> cell_machinists;
    private List<double> cell_routing_actual, cell_attended_actual, cell_lost_time_actual, cell_unaccounted_time_actual, cell_absence_actual;
    private List<int> cell_ncr_qty;
    private List<double> cell_ncr_cost;
    private List<int> cell_timelost;

    public Cell(int id, string name, double target)
    {
        cell_id = id;
        cell_name = name;
        cell_target = target;
    }
    public void setSupervisor(string name){
        cell_supervisor = name;
    }

    public void setTargets(double routings, double attended, double losttime, double unacccounted, double abscence)
    {
        cell_routing_target = routings;
        cell_attended_target = attended;
        cell_lost_time_target = losttime;
        cell_unaccounted_time_target = unacccounted;
        cell_absence_target = abscence;
    }
    public void setMachinist(string name, double routings, double attended, double lost_time, double unaccounted_time, int ncr_qty, double ncr_cost, int time_lost, double absence)
    {
        cell_machinists.Add(name);
        cell_routing_actual.Add(routings);
        cell_attended_actual.Add(attended);
        cell_lost_time_actual.Add(lost_time);
        cell_unaccounted_time_actual.Add(unaccounted_time);
        cell_ncr_qty.Add(ncr_qty);
        cell_ncr_cost.Add(ncr_cost);
        cell_timelost.Add(time_lost);
        cell_absence_actual.Add(absence);
    }


    public string CellName
    {
        get {
            return cell_name;
        }
    }

    public string Supervisor
    {
        get
        {
            return cell_supervisor;
        }
    }
    public List<string> Machinists
    {
        get
        {
            return cell_machinists;
        }
    }

}


Use nested lists and sub reports is the short answer!

i fixed it by using a constructor in the generic class
