Deleted Event On Sqldatasource And Output Parameters... Always NULL!!

I have an event:

Private Sub SqlDataSourceIncome_Deleted(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.SqlDataSourceStatusEventArgs) Handles SqlDataSourceIncome.Deleted

Dim command As SqlClient.SqlCommand

command = e.Command

If command.Parameters("@nReturnCode").Value <> 0 Then

    DROPDEAD()

End If

That  fires from:

<DeleteParameters>

<asp:Parameter Name="nDeletebyId" Type="Int64" />

<asp:Parameter Name="nOtherId" Type="Int64" />

<asp:Parameter Direction="Output" Name="nReturnCode" Type="Int64" />

<asp:Parameter Direction="Output" Name="nReturnId" Type="Int64" />

</DeleteParameters>

End Sub

 

When I:

GridViewIncome.DeleteRow(GridViewIncome.SelectedRow.RowIndex)

But nReturnCode is ALWAYS NULL... I even did a stored procedure that just:

ALTER PROCEDURE [dbo].[sp_nDeletebyId]

 @nReturnCode bigint output,

@nReturnId bigint output AS

SET @nReturnCode = 0

SET @nReturnId = 0

And STILL got nothing but the NULLS... the insert & update stuff works fine, with identical code... it's just the DELETED event that I can't seem to knock.  Has anyone seen this before?  The above sample stored proc did return 0 when executed one the server...

and, BTW, the row is deleted!
