c# - Can't get Value and DisplayMember from CheckedListBoxControl bound to LINQ -

the question has been asked before on stackoverflow might think it's duplicate, i've tried number of solutions, i'm still stuck.

i have winforms checkedlistboxcontrol bound linq query , fail value , displaymembers.

below tries value , displaymember values:

 var avail = c in dc.costcenters                        select new { item = c.costcenterid,                                 description = c.costcenterid + ": " + c.description };                 mylist.datasource = avail;                 mylist.displaymember = "description";           //retrieval:         foreach (var item in mylist.checkeditems)         {             datarowview row = item datarowview; //try 1: row empty             string displaymember = item["description"]; //try 2: cannot apply indexing [] expression of type 'object'             var x = item[0]; //try 3: cannot apply indexing [] expression of type 'object'             row3 = ((datarowview)mylist.checkeditems[item]).row; //try 5 million: compile error - invalid arguments         } 

assuming want get/display valuemembers/displaymembers: sample provide assume ienumerable<dynamic> linq query. have converted test scenario list<dynamic>:

list<dynamic> list = new list<dynamic> {     new { item = 1, description = "1: item1"},     new { item = 2, description = "2: item2"} }; 

just add bindingsource checkedlistbox:

bindingsource bindingsource = new bindingsource(list, null);  checkedlistbox1.datasource = bindingsource; checkedlistbox1.valuemember = "item"; checkedlistbox1.displaymember = "description"; 

when have selected items , want check it:

var checkeditems = checkedlistbox1.checkeditems; foreach (dynamic checkeditem in checkeditems) {     console.writeline("valuemember: " + checkeditem.item);     // or whatever code have } 

hope helps!
