That tutorial is spot-on, Michael!

If you in fact have the ObjectDataSource instance wired up to all three of your controller's methods (select,delete,update), then you need to make sure there is no code elsewhere that is wiping out the data when your page first runs ( inside an If Not IsPostBack block, perhaps)...

However, I get the vibe that you're missing some essential understanding of how the GridView and ObjectDataSource function. These controls exist so that you don't have to manually call ModuleName_SelectAll, ModuleName_Delete, etc...

FROM MICHAEL'S TUTORIAL:

<asp:ObjectDataSource ID="ObjectDataSource_ThingsForSale" runat="server" DataObjectTypeName="YourCompany.Modules.ThingsForSale.ThingsForSaleInfo"
DeleteMethod="ThingsForSale_Delete" InsertMethod="ThingsForSale_Insert" OldValuesParameterFormatString="original_{0}"
OnInit="Page_Load" SelectMethod="ThingsForSale_SelectAll" TypeName="YourCompany.Modules.ThingsForSale.ThingsForSaleController"
UpdateMethod="ThingsForSale_Update">
<SelectParameters>
<asp:Parameter DefaultValue="00" Name="ModuleId" Type="Int32" />
</SelectParameters>
</asp:ObjectDataSource>

Those large attributes above are what cause the methods on your controller to execute when the GridView needs to delete, update, or select data. In turn the controller method that the ObjectDataSource calls will execute the stored procedures. In your  controller's select method it executes: DataProvider.Instance().ExecuteReader("ModuleName_SelectAll", ModuleId)

Does this help you at all?

>1.) Does this code within "ModuleName_SelectAll" appear to have syntax to select all existing data?

This method executes the ModuleName_SelectAll stored procedure which (should) reside in you database. You can execute this stored procedure through the server explorer window in VS or VWD to see that it does in fact return what you expect.

> 2.) How do I call/execute the "ModuleName_SelectAll" within the .vb file?

If you want to call the stored procedure then use DataProvider.Instance().ExecuteReader("ModuleName_SelectAll", ModuleId)

If you want to call the method on your controller just call it.

You shouldn't have to manually do either of these. The ObjectDataSource will do all the calling for you.

> 3.) How do I associate it with only GridView3?

Give GridView3 its own ObjectDataSource instance. You can then assign whatever select, insert, update, delete methods you want to asign to that ObjectDataSource.

>4.) Where can I dictate/change the sql table it is "selecting all" from?

Within your stored procedure which is in your database.
