wpf - How to Binding composition based Observable Collection? -

say model looks shown below,

public class organization     private string _organizationname;     private list<employee> _employees;     private list<contractor> _contractors;      public string organizationname     {                 {             return _organizationname;         }         set         {             _organizationname= value;         }     }      public list<employee> employees     {         { return _employees; }         set { _employees = value; }       }      public list<contractor> contractors     {                 {             return _contractors;         }         set         {             _contractors = value;         }     } } 

}

public class employee {     public string name { get; set; }  public int empid { get; set; }      public double salary { get; set; }  } public class contractor { public string name { get; set; }      public int contractorid { get; set; }      public double experiancecredit { get; set; }  } 

i have 1 view(mainwindow) , 1 associated viewmodel(organizationviewmodel)

view(mainwindow)

has 3 controls:

1) listview -organizationlistview 2) datagrid -employeesdatagrid 3) datagrid -contractorsdatagrid

viewmodel(organizationviewmodel)

private observablecollection<organization> _organizations      public observablecollection<organization> organizations     {                 {`enter code here`             return _organizations;         }         set         {             _organizations = value;         }     } 

binding:

listview - organizationlistview - binds organizations(observablecollection) datagrid - employeesdatagrid - binds organizations.employees datagrid - contractorsdatagrid - binds organizations.contractors

i have problem accessing employees & contractors organizations(observablecollection) while trying bind respective control in view?

employeesdatagrid & contractorsdatagrid should dependent on organizationlistview

is achievable or should follow different approach?

what trying do, if understand have list of organizations, when click on 1 of organizations table of employees , contractors organization shown in data grids. right?

if so, doing hard way. want create relation between organization table , contractor table , separate relation between organization table employee table. doing poco fool's errand in view.

the many ways this, first choice typed dataset. setup 3 tables , 2 relations, create view model containing instantiated dataset. bind organization table list view , 2 relations datagrids , done!
