I am developing a very simple module for DNN 4.5.5, where i am using a RadGrid (latest version) and an ObjectDataSource. Select, Update and Delete is working perfectly, but when I do a PerformInsert, the ModuleId returns 0 (integer). How can I retrieve the ModuleId when I insert new data to the database? I am using this article http://adefwebserver.com/DotNetNukeHELP/DNN_Things4Sale/  as a template for my module.

Thanks, but your solution did not help. I also tried to use an SqlDataSource, but I am not experienced enough, so I try to stick to the documets written by Michael Washington... If I give you some of my code, maybe you see what's wrong. I guess I have been troubleshooting for too long, so I'm getting blinded by the code. 

Here is the insert code of the controller file:

        <DataObjectMethod(DataObjectMethodType.Insert)> _
        Public Shared Sub QBirthdayToday_Insert(ByVal BirthdayTodayInfo As QBirthdayTodayInfo)
            'Dim intModuleId As Integer
            DataProvider.Instance().ExecuteNonQuery("Q_spAddIndividual", BirthdayTodayInfo.ModuleId, GetNull(BirthdayTodayInfo.IndividualFirstName.ToString), GetNull(BirthdayTodayInfo.IndividualLastName.ToString), GetNull(BirthdayTodayInfo.Individual.ToString), GetNull(BirthdayTodayInfo.Day), GetNull(BirthdayTodayInfo.Month), GetNull(BirthdayTodayInfo.Year), GetNull(BirthdayTodayInfo.IsLiving))
        End Sub

Here is the definition in my info file:

 Private _ModuleId As Integer
        Public Property ModuleId() As Integer
            Get
                Return _ModuleId
            End Get
            Set(ByVal value As Integer)
                _ModuleId = value
            End Set
        End Property

And finally here is my ObjectDataSource:

<asp:Label ID="lblModuleId" runat="server"></asp:Label>
<asp:ObjectDataSource ID="ObjectDataSource_QBirthdayToday"
    runat="server"
    DataObjectTypeName="Q.Modules.BirthdayToday.QBirthdayTodayInfo"
    SelectMethod="QBirthdayToday_Select"
    InsertMethod="QBirthdayToday_Insert"
    UpdateMethod="QBirthdayToday_Update"
    DeleteMethod="QBirthdayTodayInfo_Delete"
    OldValuesParameterFormatString="original_{0}"
    OnInit="Page_Load"
    TypeName="Q.Modules.BirthdayToday.QBirthdayTodayController">
    <SelectParameters>
        <asp:Parameter DefaultValue="00" Name="ModuleId" Type="Int32" />
    </SelectParameters>
    <DeleteParameters>
        <asp:Parameter Name="Original_ID" Type="Int32" />
    </DeleteParameters>
    <UpdateParameters>
        <asp:Parameter Name="ModuleId" Type="Int32" />
        <asp:Parameter Name="Id" Type="Int32" />
        <asp:Parameter Name="IndividualFirstName" Type="String" />
        <asp:Parameter Name="IndividualLastName" Type="String" />
        <asp:Parameter Name="Individual" Type="String" />
        <asp:Parameter Name="Day" Type="Int32" />
        <asp:Parameter Name="Month" Type="Int32" />
        <asp:Parameter Name="Year" Type="Int32" />
        <asp:Parameter Name="IsLiving" Type="Int32" />
    </UpdateParameters>
    <InsertParameters>
        <asp:ControlParameter ControlID="lblModuleId" Name="ModuleId" PropertyName="Text" Type="Int16" />
        <asp:Parameter Name="IndividualFirstName" Type="String" />
        <asp:Parameter Name="IndividualLastName" Type="String" />
        <asp:Parameter Name="Individual" Type="String" />
        <asp:Parameter Name="Day" Type="Int32" />
        <asp:Parameter Name="Month" Type="Int32" />
        <asp:Parameter Name="Year" Type="Int32" />
        <asp:Parameter Name="IsLiving" Type="Int32" />
    </InsertParameters>
</asp:ObjectDataSource>

I Guess this is what you're asking for:

Protected Sub SetModuleID(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.ObjectDataSourceSelectingEventArgs) Handles ObjectDataSource_Tasks.Selecting
e.InputParameters("ModuleId") = ModuleId.ToString
End Sub
