I have a question about binding  XamDataGrid 10.2. Here is the ObservableCollection I am binding my grid to:

private ObservableCollection<IObj> _objList= new ObservableCollection<IObj>();

public ObservableCollection<IObj> ObjList{

get { return _objList; }

set{_objList=value;RaisePropertyChanged("ObjList");}

}

private IObj _currentRecord;

public IObj CurrentRecord{

get{ return _currentRecord;}

set{ if (value!= _currentRecord) _currentRecord = value; RaisePropertyChanged("CurrentRecord");}

}

In Xaml I set the binding as follows:

<igDP:XamDataGrid x:Name="xamDataGrid" DataSource="{Binding ObjList}" ActiveRecord="{Binding Path=CurrentRecord,Mode=TwoWay}" AutoFit="True" IsSynchronizedWithCurrentItem="True" UpdateMode="OnCellChangeOrLostFocus" >

I can see get and set properties of the CurrentRecord working but the set value is null. Do I need a converter? Notice that I am binding to a collection of interface rather than class implementing the interface IObj. Is that what is causing the problem? Thanks.

PS I referenced suggested way of binding ActiveRecord disussed here: http://ko.infragistics.com/community/forums/p/30668/413726.aspx#413726
