c# - How to create BindingList which is subset of DbSet while using Table Per Hierachy inheritance approach? -


i have dbset<person> contains objects of type: person, client,employee indicated discriminator in table. used table per hierarchy approach.

now try bindinglist of client set datasource of listbox.

i able set whole people table datasource want clients form table in listbox.

 public partial class listofclientsform : form {      private applicationdbcontext context;     public bindinglist<person> clients { get; set; }         public bindingsource psource { get; set; }         public listofclientsform() {             initializecomponent();             context = new applicationdbcontext();             populatelistbox();         }          public void populatelistbox() {             context.people.load();             clients = context.people.local.tobindinglist();             clients.allowedit = true;             clients.allownew = true;             psource = new bindingsource();             psource.datasource = clients;             clientslistbox.datasource = psource; //now whole contents of array in listbox         }      }

to conclude wish have public bindinglist<clients> clients { get; set; } instead of public bindinglist<person> clients { get; set; }.

if want bring clients elements context, can filter people before load them:

context.people.oftype<client>().load(); //you going clients clients = context.people.local.tobindinglist();
