Get return value from ObjectDataSource

Sub SomeGridView_Inserted(s As Object, e As ObjectDataSourceStatusEventArgs)
  Dim intId As Integer
  intId = e.OutputParameters("Return")
End Sub


<asp:ObjectDataSource ID="ObjectDataSource1" Runat="server"
        TypeName = "MyNamespace.MyObject"
        InsertMethod = "InsertData">
    <InsertParameters>
        <asp:Parameter Direction="InputOutput" Name="Return" Type="Object" />
    </InsertParameters>
</asp:ObjectDataSource>

Thanks for responding!
I'm actually using a DetailsView to do the insert.
It's telling me the data type of the second parameter needs to be DetailsViewInsertedEventArgs, not ObjectDataSourceStatusEventArgs.  Any ideas?  Am I missing something?

Closer, but I still can't get it to work.
This is basically what I have:

<asp:ObjectDataSource ID="srcClient" runat="server"
                TypeName="Intranet.BusinessLogicLayer.Client"
                InsertMethod="Insert"
                OnInserted="Client_Inserted" >
            <InsertParameters>
                <asp:Parameter Direction="InputOutput" Name="ReturnValue" Type="Object" />
            </InsertParameters>
</asp:ObjectDataSource>

Sub Client_Inserted(ByVal s As Object, ByVal e As ObjectDataSourceStatusEventArgs)
        Dim intId As Integer
        intId = e.OutputParameters("ReturnValue")
        reponse.write(intId)
End Sub

In my business logic layer this is what the Sub looks like:
Public Shared Sub Insert(ByVal ReturnValue As Object, _
                                ByVal Name As String, _
                                ByVal ShortName As String, _
                                ByVal ClientTypeID As Integer, _
                                ByVal CurrentClient As Boolean, _
                                ByVal ClientSince As String, _
                                ByVal Notes As String, _
                                ByVal CRMCompanyID As Integer)
            ReturnValue = 5
End Sub

Given this, '5' should be written to the screen, but '0' is instead.  What am I doing wrong?

Are you calling a stored procedure with the objectdatasource? I have tried using a return value, but i couldn't do it through a datasource without designating a parameter as output ie:

CREATE PROCEDURE dbo.[usr_InsertNew]
      (@ProjectID int OUTPUT )

And then in the proc:

SELECT @ProjectID = SCOPE_IDENTITY()
RETURN @ProjectID


You can also do this without a datasource like so:

SqlConnection Connection = new SqlConnection(ConfigurationManager.ConnectionStrings["MyConn"]);
SqlCommand Command = new SqlCommand("usr_InsertNew", Connection);
Command.CommandType = CommandType.StoredProcedure;

SqlParameter sqlParam = new SqlParameter();
sqlParam.ParameterName = "@ReturnVal";
sqlParam.Direction = ParameterDirection.Output;
sqlParam.Size = 4;

The ObjectDataSource isn't calling a stored procedure.  If you look closely at the code I've provided you can see it's calling a subroutine in a class I've written (Intranet.BusinessLogicLayer.Client).  To test this, all the ObjectDataSource does is call a subroutine (Insert) that sets the inputoutput parameter equal to 5, so we're not dealing with stored procedures at all at this point.

I got it to work.
I changed the "Direction" on my InsertParemeters back to "ReturnValue" so my ObjectDataSouce looks like:
<asp:ObjectDataSource ID="srcClient" runat="server"
                TypeName="Intranet.BusinessLogicLayer.Client"
                InsertMethod="Insert"
                OnInserted="Client_Inserted" >
            <InsertParameters>
                <asp:Parameter Direction="ReturnValue" Name="ReturnValue" Type="Int32" />
            </InsertParameters>
</asp:ObjectDataSource>

I changed e.OutputParameters to e.ReturnValue so my code behind looks like:
Sub Client_Inserted(ByVal s As Object, ByVal e As ObjectDataSourceStatusEventArgs)
        Dim intId As Integer
        intId = e.ReturnValue
        response.write(intId)
End Sub

And finally I changed the Insert() subroutine to a function and return the value I need.

Thanks for your help strickdd!
