Hi, I'm using xamDataGrid for adding hierarchical data.. My problem is that when adding new value only first hierachy is visible.. (no plus sign for adding the other hierachy).. But when i select record which was already added, i can see plus sign and also add second hierarchy.. Is it possible to fill all data from "add row"? I let the xamdatagrid to create fieldlayout automaticaly.. As a data source i use BindingList public class Test() { private BindingList _list; public BindingList List { get{return _list;} set{_list = value;} } private string _name; public string Name { get{return _name;} set{_name = value;} } } When adding new record i'm only able to fill Name column, but after adding new record and selecting it i can see "the plus sign" and i'm able to add also values to the List property.. Is there anyway how to add them in one step? Thanks Tomas
