c# - Databinding in Silverlight with RIA Services -

i'm trying display content of table in combobox.

i'm using mvvm pattern , in viewmodel class if write works:

private ienumerable<eventtype> _eventtypes;  public manageprofilemodel()         {             _referencedata = new referencedatacontext();              _referencedata.load(_referencedata.geteventtypesquery(), false);              _eventtypes = _referencedata.eventtypes;         } 

like combobox displaying data.

however, want _eventtypes list:

private list<eventtype> _eventtypes; 

but if write this:

public manageprofilemodel()         {             _referencedata = new referencedatacontext();              _referencedata.load(_referencedata.geteventtypesquery(), false);              _eventtypes = _referencedata.eventtypes.tolist();         } 

then combobox empty. wrong that?

i want use list, because want able add , remove data in list.

best regards.
