Reportviewer

[RedLars]

Afternoon.

Having a bit of a problem with the ReportViewer that comes with VS2005.
I'd like to generate reports based on a collection of a object. Here is
the source;

public class DataColl
{
List<DataXList;
public DataColl()
{
List = new List<DataX>();
List.Add(new DataX(3, "RIO"));
List.Add(new DataX(66, "RCU"));
List.Add(new DataX(999, "COP"));
}
}

public class DataX
{
private int index;
private string name;
public DataX(int i, string n)
{
index = i;
name= n;
}
public int Index { get { return index;} }
public string Name { get { return name;} }
}

Have created an Report document (.rdlc) and tried adding both DataX and
DataColl as Data source to the report. In the report I've currently
setup a table with two columns with expressions =Fields!Index.Value and
=Fields!Name.Value.

I've used this code to init the report:

private void Report_Load(object sender, EventArgs e)
{
DataColl collection = new DataColl();
DataX d1 = new DataX(1, "TEST");

ReportDataSource reportdatasource = new ReportDataSource();
reportdatasource.Name = "_TEST_";
reportdatasource.Value = d1; // Exception (see below)

reportViewer1.ProcessingMode = ProcessingMode.Local;
reportViewer1.LocalReport.DataSources.Add(reportda tasource);
reportViewer1.RefreshReport();
}

When running the code I get the error below when trying to add DataX as
the reportdatasource value. Have also tried using DataColl as
datasource but get the same error.
ArgumentExcpetion was not handled (Value does not fall within the
expected range).

I'm stuck at the moment and was hoping for some assistance.
