[RESOLVED] Not all child rows showing in repeater

I thought I had my previous thread resolved over nesting a third-level repeater, but it seems now that the third level that displays the files only shows the first child, not the rest. The second-level repeater displays all children correctly. Does anyone know why this is the case?

Code:

---

<asp:Repeater ID="rptAll" runat="server">
    <ItemTemplate>
    <p>Group: <%#DirectCast(Container.dataitem, Data.DataRowView)("groupid")%></p>
        <asp:Repeater ID="rptChildren" runat="server" DataSource='<%# DirectCast(Container.dataitem, Data.DataRowView).CreateChildView("Groups_FileCategories") %>'>
        <ItemTemplate>
        <p>Category: <%#DirectCast(Container.dataitem, Data.DataRowView)("CategoryID")%> <%#DirectCast(Container.DataItem, Data.DataRowView)("GroupID")%></p>
            <asp:Repeater ID="rptFiles" runat="server" DataSource='<%# DirectCast(Container.Dataitem, Data.DataRowView).CreateChildView("FileCategories_Files") %>'>
            <ItemTemplate>
            <p>File: <%#DirectCast(Container.DataItem, Data.DataRowView)("FileName")%></p>
            </ItemTemplate>
            </asp:Repeater>
        </ItemTemplate>
        </asp:Repeater>
    </ItemTemplate>
</asp:Repeater>

**Update - I have checked the dataset, and all five records are in the files table, and the relationships have to be correct or else the first record wouldn't even show...

I moved the datasource code to the codebehind, and the Files_ItemDataBound event fires all five times for the files, yet only the first ones in each group are displayed on the page...

Code:

'codebehind for itemdatabound
 Protected Sub Groups_ItemDataBound(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.RepeaterItemEventArgs)
        If e.Item.ItemType = ListItemType.Item OrElse e.Item.ItemType = ListItemType.AlternatingItem Then
            Dim MyRpt As Repeater = e.Item.FindControl("rptChildren")
            If MyRpt IsNot Nothing Then
                MyRpt.DataSource = DirectCast(e.Item.DataItem, Data.DataRowView).CreateChildView("Groups_FileCategories")
                MyRpt.DataBind()
            End If
        End If
    End Sub
    Protected Sub Categories_ItemDataBound(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.RepeaterItemEventArgs)
        If e.Item.ItemType = ListItemType.Item OrElse e.Item.ItemType = ListItemType.AlternatingItem Then
            Dim MyRpt As Repeater = e.Item.FindControl("rptFiles")
            If MyRpt IsNot Nothing Then
                MyRpt.DataSource = DirectCast(e.Item.DataItem, Data.DataRowView).CreateChildView("FileCategories_Files")
                MyRpt.DataBind()
            End If
        End If
    End Sub
    Protected Sub Files_ItemDataBound(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.RepeaterItemEventArgs)
        If e.Item.ItemType = ListItemType.Item OrElse e.Item.ItemType = ListItemType.AlternatingItem Then
          '****** GETS HERE ALL FIVE TIMES, yet only three show (two are in the same group) ******
        End If
    End Sub
