I am using XamWebTree.v9.2 and building nodes dynamically in code like this:

foreach (var ic in ics.Entities)
                {
                    XamWebTreeItem newNode = new XamWebTreeItem();
                   
                    newNode.Name = ic.IconID;
                    Image img = new Image();
                    img.Source = new BitmapImage(new Uri(ic.IconURL, UriKind.Relative));
                    img.Width = 30;
                    img.Height = 30;
                   
                
                    newNode.CollapsedIcon = img

                    newNode.Header = ic.IconDesc;
                    newNode.HorizontalAlignment = HorizontalAlignment.Left;
                    newNode.Tag = ic.IconURL;
                
                    newNode.Margin = new Thickness(0, 0, 0, 3);
                       
                        LegendTree.Items.Add(newNode);
                  

                }

When user double click on image or text, image disapppers and still gone even when select diffrent node. When double click again on same node, image shows back.

How can I prevent this from happenned or don't let user double click on tree node? 

Thanks
