ReportViewer problem

Hi guys,

I'm having problems when trying to load different .rdlc files dynamically into a single ReportViewer control.

Here's the code:

Code:

    private void LoadUserControl(string type)
    {
        Label lblTitle = (Label)Parent.FindControl("lblTitle");

        ReportViewer1.LocalReport.DataSources.Clear();
        Microsoft.Reporting.WebForms.ReportDataSource rpt = new Microsoft.Reporting.WebForms.ReportDataSource();
        rpt.Name = "MyDataSource";

        switch (Request["mode"].ToLower())
        {
            case "view":
                switch (type.ToLower())
                {
                    case "view1":
                        ReportViewer1.LocalReport.ReportPath = Server.MapPath(@"~/Reports/View1.rdlc");

                        lblTitle.Text = "VIEW 1";
                        // ods: ObjectDataSource
                        rpt.DataSourceId = odsView1.ID;
                        rpt.Value = odsView1;
                        break;
                    case "view2":
                        ReportViewer1.LocalReport.ReportPath = Server.MapPath(@"~/Reports/View2.rdlc");
                        lblTitle.Text = "VIEW2";
                        // ods: ObjectDataSource
                        rpt.DataSourceId = odsView2.ID;
                        rpt.Value = odsView2;
                        break;
                }
                break;
        }

        ReportViewer1.LocalReport.DataSources.Add(rpt);
        ReportViewer1.LocalReport.Refresh();
    }

A full screen of the code is available at http://img262.imageshack.us/my.php?image=codebe3.png

The error message I keep getting is "A data source instance has not been supplied for the data source 'Reports_NepokretnostiIzvestajPoOsnovuOduzimanja'. "

Thanks in advance
