ObjectDataSource not passing parameter to report viewer stored proc (sql server)

I have an ObjectDataSource feeding data to a report viewer control, but when I try to give the objectdatasource a parameter it should be expecting (based on the stored proc that's pulling the data) and the GetData method in the XSD file, I get the error:
An error has occurred during report processing.ObjectDataSource 'ObjectDataSource2' could not find a non-generic method 'GetData' that has parameters: Date.The table adapter in the XDS shows GetData(@.Date), and I'm trying to bind the objectdatasource to my report viewer like this:

PlaceHolder1.Controls.Clear()
Dim rv As New Microsoft.Reporting.WebForms.ReportViewer
PlaceHolder1.Controls.Add(rv)
rv.LocalReport.DataSources.Clear()
ObjectDataSource2.TypeName = "DS_ClosedProjectsSnap2TableAdapters.reports_closedin7days_2TableAdapter"
ObjectDataSource2.SelectParameters.Clear()
ObjectDataSource2.SelectParameters.Add("Date", d_collectiondate.SelectedValue)
ObjectDataSource2.DataBind()
rv.LocalReport.ReportPath = "secure\reports\ClosedProjectsSnap.rdlc"
rv.LocalReport.EnableHyperlinks = True
rv.LocalReport.DataSources.Clear()
rv.ProcessingMode = ProcessingMode.Local
rv.LocalReport.DataSources.Add(New ReportDataSource("DS_ClosedProjectsSnap2_reports_closedin7days_2", ObjectDataSource2))
rv.DataBind()

I can't see why this wouldn't work, so I would really appreciate any ideas anybody has.

Thanks

I used to have this error, but all I did to fix it was configure the datasource and make sure each paramter was assigned to textbox controls which i added above the ReportViewer.
