.net - EF 4 Filter sub collection -

im trying maingroups related entities. , filter buildingpartdata collection without affecting of other entities. have pretty tried every thing can think of no luck.

 test.contextoptions.lazyloadingenabled = false;          var buildingpartmaingroups = (from buildingpartmaingroup in test.buildingpartmaingroup                                       buildingpartsubgroup in buildingpartmaingroup.buildingpartsubgroup                                       buildingpart in buildingpartsubgroup.buildingpart                                       buildingpartdata in buildingpart.buildingpartdata                                       buildingpartdata.statuspendingapprove == true                                       //let buildingpartdata = buildingpartmaingroup.buildingpartsubgroup.where(x => x.buildingpart.any(o => o.buildingpartdata.any(y => y.statuspendingapprove == true)))                              select new                              {                                  buildingpartmaingroups = buildingpartmaingroup,                                  buildingpartdatas = buildingpartdata                               }).tolist().select(c => c.buildingpartmaingroups);          foreach (var bb in buildingpartmaingroups)         {             foreach(var tt in bb.buildingpartsubgroup)             {                 foreach (var oo in tt.buildingpart)                 {                     foreach (var ww in oo.buildingpartdata)                     {                         bool tes4t = ww.statuspendingapprove;                     }                 }             }         }

cant insert images yet..

var buildingpartmaingroups = test.buildingpartmaingroup.include("buildingpartsubgroup.buildingpart.buildingpartdata").                                         where(bpmg => bpmg.buildingpartsubgroup.                                             any(o => o.buildingpart.                                                 any(x => x.buildingpartdata.                                                     any(u => u.statuspendingapprove == true))));

it filtered buildingpartmaingroup entity. have buildingpartmaingroup entities, condition / filter on buildingpartdata

did think of like:

context.buildingpartmaingroup  .inlcude("buildingpartsubgroups.buildingparts.buildingpartdata")  .where<buildingpartmaingroup>(bpmg => bpmg.buildingpartsubgroups.any<buildingpartsubgroup>(etc...
