Default Capturing RETURNVALUE from SP using FormView


I'm using FromView to Insert record into a DB. My SP checks for the existence and returns -1 if record already exists. I know that my SP returns -1 but how do I capture that into FormView and display error message to the user? All I get is the "Agreement was created" regardless of what SP returns.
Your help is appreciated.

Here is the code I'm using:
Protected Sub OnInserted(sender As Object, e As System.Web.UI.WebControls.SqlDataSourceStatusEvent Args)
        Dim retValParam As New SqlParameter("@RETURN_VALUE", SqlDbType.Int)
        retValParam.Direction = ParameterDirection.ReturnValue

        Dim valParam As Integer = Convert.ToInt32(retValParam.Value)
        If valParam = -1 Then
          lblMessage.Text = "The Account ID is not valid"
        if valParam = -2 then
          lblMessage.Text = "Agreement ID already exists"
          lblMessage.Text = "Agreement was created"
        End If
      end if
  End Sub

and parts of ASPX page with FromView:

 InsertCommand="spNew_Agreement" OnInserted="OnInserted">

  <asp:ControlParameter Name="Acct_Name" ControlID="txtAcct_Name" />
  <asp:Parameter Name="acct_id" Type="string" />
  <asp:Parameter Name="agreement_id" Type="string" />
  <asp:Parameter Name="return_value" Type="int32" Direction="ReturnValue" />

Of course you can't get return value that way. You are creating new parameter _after_ the procedure has been executed. You should check SqlDataSourceStatusEventArgs class and SqlDataSourceStatusEventArgs.Command property from MSDN.
