Body
I have a <code>ObjectDataSource</code> Which Calls business layer methods to update EF and save. I have this weird problem. Following is ODS markup: <pre><code><asp:ObjectDataSource ID="odsDeviceForm" runat="server" ypeName="Spectre.BLL..DeviceManager" DataObjectTypeName="Model.Device" SelectMethod="GetById" InsertMethod="Insert" oninserting="OnItemInserting" UpdateMethod="UpdateEx" oninserted="OnItemInserted" onupdated="OnItemUpdated" onupdating="OnItemUpdating" onobjectcreated="OnOdsObjectCreated" onselected="OnOdsItemSelected" ConflictDetection="CompareAllValues" OldValuesParameterFormatString="orig{0}" > <SelectParameters> <asp:SessionParameter Name="primaryKey" SessionField="SelectedDeviceId" Type="Int32" /> </SelectParameters> </code></pre> Following is BLL and repositoryCode: BLL: <pre><code>public void UpdateEx(T entity, T origentity) { try { repository.Update(origentity, entity); repository.Save(); } catch (Exception) { throw; } } </code></pre> Repository: <pre><code>public void Update(T orig, T newEntity) { myContext.Entry<T>(newEntity).CurrentValues.SetValues(newEntity); } </code></pre> When This code runs I get an exception: <blockquote> Member 'CurrentValues' cannot be called for the entity of type 'Device' because the entity does not exist in the context. To add an entity to the context call the Add or Attach method of DbSet. </blockquote> But if I do dbset.attach then I get exception that the entity already exists. I have no idea what can I do, seems like a circular problem to me. I have gone half bald pulling my hair over this. Please help.

Guidance

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
