Open a report from a dropdownlist

HI,

i currently open my reports using a onclick_button and the code behind of;

            protected void Button1_Click(object sender, EventArgs e)
            {
                ReportViewer1.ProcessingMode = Microsoft.Reporting.WebForms.ProcessingMode.Remote;
                ReportViewer1.ServerReport.ReportServerUrl = new Uri("");
                ReportViewer1.ServerReport.ReportPath = "";
                ReportViewer1.ServerReport.Refresh();
            }

what i really want is to have a dropdown list with each report added as an item, once a report is selected you click a GET REPORT button which would load the report. Does anybody have an idea of how this could be done?

Thanks
