        List<ReportVentasFamiliaDto> dataSource = new List<ReportVentasFamiliaDto>();
        dataSource.Add(new ReportVentasFamiliaDto()
            PorcentajeIva = 10,
            FamiliaNombre = "Familia"
        var objectDataSource = new Telerik.Reporting.ObjectDataSource();
        objectDataSource.DataSource = dataSource;
        objectDataSource.DataMember = "table1";
        var typeReportSource = new TypeReportSource() {
            TypeName = "Report1.trdp" };
        typeReportSource.Parameters.Add(new Parameter()
            Name = "objectDataSource2",
            Value = objectDataSource
        typeReportSource.Parameters.Add(new Parameter()

    Hello Francisco,

    I noticed that you have a TRDP report but you are trying to use TypeReportSource which is required for CS/VB reports. Reports created with the Standalone designer (TRDP/X files) may be passed with UriReportSource.

    Note that assigning the DataSource to the report or data items can be done in a  custom report resolver in the Reports Controller. You need to construct the report instance in the Resolve() method of the custom report resolver. Then the report has to be returned wrapped in an InstanceReportSource, which is the only server-side ReportSource that can take Report instance. DataSource cannot be passed through a Report Parameter.

    Generally, we do not recommend report definition modifications in run time. You may set the DataSource in the report definition. Note that the data source component does not actually hold any data. It only tells the Reporting engine where to fetch the data from. For the ObjectDataSource in run time, the Reporting engine will invoke the DataMember through System.Reflection to get the data. You may customize the received data by setting parameters to the ObjectDataSource.
