OneToOneViewRelationShip does not work without nesting the FormViews

Got an insertpage working for a main table and two tables with 1-1 relationship using nested FormViews and OneToOneRelationships.

As I understood from a comment from Bobby Diaz the same should also work without nesting as long as the FormViews and OneToOneRelationships are inside of the same NamingContainer.

If this would work correctly it would be possible to replace the FormView by a MultiFormView with an InsertItemTemplatePath and reuse a generated usercontrol with input fields.

However, an unnested version of the page where FormViews and OneToOneRelationships are placed inside a View fails to work.

Tanno,

 You should be fine to use the OneToOneRelationships control. Can you post a sample ... we could help you to narrow the problem. Please also make sure you set the DataKeyNames for every FormView

Mike thanks for your reply. The sample is below:

     <asp:View ID="View1" runat="server">

     <asp:FormView ID="BedrijfFormView" runat="server" DefaultMode="Insert" DataSourceID="BedrijfDataSource"
      DataKeyNames="BedrijfID">
      <InsertItemTemplate>
         ....SNIP....
      </InsertItemTemplate>
    </asp:FormView>
   
    <asp:FormView ID="BedrijfsProfielFormView" runat="server" DefaultMode="Insert" DataSourceID="BedrijfsProfielDataSource"

      <InsertItemTemplate>

Tanno,

From what i understand the relationship controls do not work with MultiView and in order to achieve single-click update call, children controls have to be nested.

Check that thread http://community.codesmithtools.com/forums/thread/16533.aspx

Hi Mike

Let me tell you my observations:

Nesting only the FormViews and leaving the OneToOneViewRelationships outside the nested FormViews works correctly.

Putting everything inside a MultiView does not make a difference, it remains working correctly. 

Getting a single-click insert for the FormViews cannnot be the reason that nesting of the FormViews is necessary, since I could get also a single-click insert by calling all three FormView.InsertItem() methods within a button OnClick event, but that doesn't not work.

First I thought that the problem might perhaps have to do with event order that needs to be nested, so I placed the FormView.InsertItem() methods of the related tables within the OnItemInserted event of the insert button of the FormView of the main table.    

But that also doesn't work, and the reason why it wouldn't work remains unclear to me.

It can't be a scope problem can it ?

regards

Tanno
