Hi,
i need to implement a generic save function that take care of add or not (that means the entity is already loaded/added) entities to the the context without running a query to test existence. DbCtx.Add(entity) raise an error that I could catch, but is this the only viable method to do that? Is There a method to access entities currently loaded/added to the context?
thank you
best regards

Hello AndreaT,
Add a new partial class to your generated context class. There you can add the functionality:
public bool IsManaged (object o)
{
return Telerik.OpenAccess.Database.GetContext(o) != null;
}
public bool IsManagedByMe(object o)
{
return Telerik.OpenAccess.Database.GetContext(o) == GetScope()
}

Hi Jan,
thank you. I dont understand where GetScope() come from.
public bool IsManagedByMe(object o)

Hello AndreaT,
This comes from the base class of your generated context class, OpenAccessContext, it has a protected method GetScope()
