Hi,

I am trying to connect an EntityDataSource to an Entity Framework Model.  When I enter "WBF_DataEntities" for the DefaultContainerName I get the error

EntitySet 'WBF_DataEntities' that was specified in page markup does not exist on the Container

I am fairly sure, although I certainly could be wrong, the the container name is WBF_DataEntities.  The namespace for the data model is WBF_DataModel.  I tried using this but I get the error

The specified default EntityContainer name 'WBF_DataModel' could not be found in the mapping and metadata information.
Parameter name: defaultContainerName

I will be happy to upload any code that you need to look at.  I just don't know exactly what someone needs to see to try to help me with this problem.  I have spent the last three hours researching on the Internet and have not been able to find a solution.

Thanks,

Doug

have you tried "WBF_DataEntity" by any chance?

send us your .edmx file and the problematic page markup so we can help you out.

No, hadn't tried WBF_DataEntity, so tried it and received

The specified default EntityContainer name 'WBF_DataEntity' could not be found in the mapping and metadata information.
Parameter name: defaultContainerName

Per your request I have attached the .edmx file (I had to add a .txt extension to it becuase EE would not let me upload it with the edmx extension) and problematic page along with a couple of others just in case.

Thanks,

Doug

I am a bit rusty with EF... That said i believe your container name is WBF_DataEntities but it's the EntitySetName which is wrong. What are you trying to display with that EntityDataSource? If it is "newsletters", do this for example:

 
<asp:EntityDataSource ID="EntityDataSource1" runat="server"
         ConnectionString="name=WBF_DataEntities"
        DefaultContainerName="WBF_DataEntities"
        EnableFlattening="false"
        EntitySetName="NewsLetters"
         OnQueryCreated="EntityDataSource1_QueryCreated">
    </asp:EntityDataSource>

Open in new window


Also, did you try doing this through the wizard? It will give you all possible values in a drop down which can be less of an hassle :-)
