EntityDataSourceFilter inside DetailsView

Hello, people!

I'm just about to finish a project, but I am stuck at something that, hopefully, is somthing silly I am missing...

I have a DetailsView attached to an ObjectDataSource (the DataSource was created with NetTiers, if this is relevant information). I can't make it work as desired if the DataSource returns only one record, but nothing wrong happens with two or more. In the particular case in which i have only one record and try to call any functionality, I receive the error message "Databind methods such as Bind(), Eval() and XPath() are only allowed in the context of a DataBound Control" (I can't remember if these are the actual words, but that's the spirit).

 
This is how the Filter is used inside the DetailsView:

                            <asp:TemplateField HeaderText="AddressType">
                                <ItemTemplate>
                                    <asp:Repeater runat="server" ID="rptAddressType"
                                        DataSourceID="AddressTypeFilter">
                                        <ItemTemplate>
                                             <%# Eval("TypeName") %>
                                        </ItemTemplate>   
                                    </asp:Repeater>

                                    <data:EntityDataSourceFilter runat="server"
                                        ID="AddressTypeFilter"
                                        DataSourceID="AddressTypeDataSource"
                                        EnableViewState="true"
                                        Filter='<%# String.Format("AddressTypeSeq = {0}", Eval("AddressTypeSeq")) %>'
                                    />

                                    <data:AddressTypeDataSource runat="server"
                                        ID="AddressTypeDataSource" SelectMethod="GetAll">
                                    </data:AddressTypeDataSource>
                                   
                                </ItemTemplate>
                            </asp:TemplateField>

 As I said before - the strange thing is that it works sometimes, others it doesn't, and I still couldn't figure out why... Can anyone help me?

 
Thank you,

Thiago. 

Thiago,

Try using DeepLoad method instead, to get the AddressType, see the example bellow:

<asp:DetailsView runat="server" ID="DetailsView" DataSourceID="CustomersDataSource"
    AllowPaging="true" AutoGenerateRows="True"
>
<Fields>
    <asp:TemplateField HeaderText="AddressType">
        <ItemTemplate>
            <asp:Repeater runat="server" ID="rptAddressType"
                DataSource='<%# Eval("OrdersCollection")%>'>
                <ItemTemplate>
                     <%# Eval("OrderDate")%>
                </ItemTemplate>  
            </asp:Repeater>         
        </ItemTemplate>
    </asp:TemplateField>
   
</Fields>
</asp:DetailsView>

<data:CustomersDataSource ID="CustomersDataSource" runat="server"
    SelectMethod="GetAll" EnableDeepLoad="true"
>
<DeepLoadProperties Method="IncludeChildren" Recursive="False">
     <Types>
        <data:CustomersProperty Name="OrdersCollection"/>
    </Types>
</DeepLoadProperties>
</data:CustomersDataSource>

I tried to, but an attempt to load the page returns me another databinding error - the entity does not contains a propoerty with the name "OrdersCollection" (or whatever name I set)...
