SubReport in a web application error Data retrieval failed for the subreport

Hi,

I am trying to create a report in a web application. The report is supposed to have a sub report in it.

What I did was create 2 reports.

Report1 (Master Report)

Report2 (SubReport)

I added parameters to the reports. then I dropped a subreport control on the report1. and set its properties to reference to Report2.

I also set the parameter for the subreport.

But it gave me the error

The Code is below

<asp:ScriptManager ID="ScriptManager1" runat="server"></asp:ScriptManager><asp:TextBox ID="TextBox1" runat="server">2</asp:TextBox><asp:Button ID="Button1" runat="server" onclick="Button1_Click" Text="Button" /><rsweb:ReportViewer ID="ReportViewer1" runat="server" Font-Names="Verdana" 
            Font-Size="8pt" InteractiveDeviceInfos="(Collection)" 
            WaitMessageFont-Names="Verdana" WaitMessageFont-Size="14pt" Width="636px" 
            Height="397px" style="margin-right: 0px"><LocalReport ReportPath="Report1.rdlc"><DataSources><rsweb:ReportDataSource DataSourceId="ObjectDataSource1" Name="DataSet1" /><rsweb:ReportDataSource DataSourceId="ObjectDataSource2" Name="DataSet2" /></DataSources></LocalReport></rsweb:ReportViewer><asp:ObjectDataSource ID="ObjectDataSource2" runat="server" 
            OldValuesParameterFormatString="original_{0}" SelectMethod="GetData" 
            TypeName="PRMSReports.PRMSReportsTableAdapters.ExpenditureViewTableAdapter"><SelectParameters><asp:ControlParameter ControlID="TextBox1" DefaultValue="2" Name="projectid" 
                    PropertyName="Text" Type="Int32" /></SelectParameters></asp:ObjectDataSource><asp:ObjectDataSource ID="ObjectDataSource1" runat="server" 
            DeleteMethod="Delete" InsertMethod="Insert" 
            OldValuesParameterFormatString="original_{0}" SelectMethod="GetData" 
            TypeName="PRMSReports.PRMSReportsTableAdapters.Project_ProfileTableAdapter" 
            UpdateMethod="Update"><DeleteParameters><asp:Parameter Name="Original_Project_ID" Type="Int32" /></DeleteParameters><InsertParameters><asp:Parameter Name="Project_Title" Type="String" /></InsertParameters><SelectParameters><asp:ControlParameter ControlID="TextBox1" DefaultValue="2" Name="projectid" 
                    PropertyName="Text" Type="Int32" /></SelectParameters><UpdateParameters><asp:Parameter Name="Project_Title" Type="String" /><asp:Parameter Name="Original_Project_ID" Type="Int32" /></UpdateParameters></asp:ObjectDataSource>

the code behind file has the following code

protected void Page_Load(object sender, EventArgs e)
        {
            ReportViewer1.LocalReport.SubreportProcessing += SetSubDataSource;
            //this.ReportViewer1.LocalReport.SubreportProcessing += new SubreportProcessingEventHandler(SubreportProcessingEventHandler);
            this.ReportViewer1.LocalReport.ShowDetailedSubreportMessages = true;
            this.ReportViewer1.LocalReport.Refresh();
        }

        protected void Button1_Click(object sender, EventArgs e)
        {
            string name = TextBox1.Text;
            ObjectDataSource1.SelectParameters["projectid"].DefaultValue = name;
            ObjectDataSource1.DataBind();
            ReportViewer1.LocalReport.SubreportProcessing += SetSubDataSource;
            this.ReportViewer1.LocalReport.Refresh();
        }

        protected void SetSubDataSource(object sender, SubreportProcessingEventArgs e)
        {
            int Per_ID = Convert.ToInt32(TextBox1.Text);
            ExpenditureViewTableAdapter dt1 = new ExpenditureViewTableAdapter();
            dynamic rds = new ReportDataSource();
            rds.Name = "DataSet2";
            rds.Value = dt1.GetData(Per_ID);
            e.DataSources.Add(rds);
        }

Please note that i am trying to do this in a web application and not a report project. Help Needed.

Thanks
