HI All

I am building a module which displays a GridView and and a Detailsview when a row on the gridview is selected.

I have created a module with the standard data access layers as defined by the module creation steps.

1. I have binded the Gridview to an object datasource succesfully which displays data as per select method. I have set the datakeyname accordingly. >> The GridView works fine without the steps below.
2. I have specified the Gridview control's datakey column as a parameter on a new object datasource with a different select method created in the BLL which accepts the datakeyname as a parameter from the GridView.
3. I have binded the Detailsview to the new object datasource and have also set the datakeyname the same on the detailsview.

I then get a Exception has been thrown by the target of an invocation error.

Any ideas what might be wrong. Am i completely doing this wrong?

Do i have to do this differently using custom business objects as per DNN module template ?

Thanks for any help, pointers or comments.

Have a look at:

Super-Fast Super-Easy Module (DAL+)

I have a GridView connected to a Details View. I am using pure OO design using Generics and Object Data Sources. This is not exactly what you're looking for but It is the closest thing I can find. What you want to do is possible. If you look in my tutorial you will see I have code such as this:

Protected Sub SetModuleId(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.ObjectDataSourceSelectingEventArgs) Handles ObjectDataSource_ThingsForSale.Selecting

e.InputParameters("ModuleId") = ModuleId.ToString

End Sub

This is the sort of code needed to inject the proper parameters ijnto the Object Data Source controls to make it work.
