Hi, I am having problems getting items on UltraTree to enter edit moode.

I have set

   m_ultraTree.DataSource = new AList();

this gives me a two level tree, adding and removing items to the  Alist instance causes items to appear on the Tree.

Now I wish to be able to edit the Name (label) of each instance of AClass on the tree and have the underleying  AClass item. So I have done the following

   m_ultraTree.NodeLevelOverrides.Add(_override1);

   _override1.ShowColumns = DefaultableBoolean.False;

   _override1.UseEditor = DefaultableBoolean.True;

   _override1.LabelEdit = DefaultableBoolean.True

As a test I have added the following as a DoubleClick event handeler

    private void m_ultraTree_DoubleClick(object sender, EventArgs e)

    {

        UltraTreeNode node = m_portsTree.SelectedNodes[0];

        node.BeginEdit();

        node.EditorResolved.Value = "change";

        node.EndEdit(false);

    }

This method fails on node.EditorResolved.Value = "change" with the exception "Can't access the 'Value' property when not in edit mode".

Ok thinking I need to edit as cell instead I tried

    private void m_portsTree_DoubleClick(object sender, EventArgs e)

    {

        UltraTreeNode node = m_portsTree.SelectedNodes[0];

        UltraTreeNodeColumn column = node.DataColumnSetResolved.Columns["Name"];

        column.AllowCellEdit = AllowCellEdit.Full;

        bool c = node.BeginCellEdit(column);

        column.EditorResolved.Value = "fff";

        node.EndCellEdit(true);

    }

As before I get an exception and c is false.

How can I get this code to work.

FYI there is the Alist and AClass.

    public class AList : BindingList<AClass>

    {

    }

    public class AClass: INotifyPropertyChanged

    {

        public event PropertyChangedEventHandler PropertyChanged;

        private string m_name;

        private readonly BindingList<string> m_bList;

        public AClass (string name)

        {

            m_name = name;

            m_bList = new BindingList<string> ();

        }

        public string Name

        {

            get { return m_name; }

            set

            {

                m_name = value;

                if (PropertyChanged != null)

                {

                    PropertyChanged(this, new PropertyChangedEventArgs("Name"));

                }

            }

        }

        public BindingList<string> Blist

        {

            get { return m_bList; }

        }

    }
