viewmodel

namespace my.viewmodels {     public class itemviewmodel : observableobject     {         private itemmodel _model;          public itemviewmodel(itemmodel model)         {             _model = model;         }          public string name { { return _model.name; } }     } } 

xaml

error:

a twoway or onewaytosource binding cannot work on read-only property 'name' 

i'm trying databinding read-only property viewmodel. i've set binding mode oneway.. yet still throws error above. i'm out of clues! appreciated.

to use oneway binding property should has , set. in case, fix problem add set property this:

public string name { private set; { return _model.name; }
