Question

I have ultraTree (infragistics tree) which is created at design time and it has custom class as ‘Tag’. I have List as member variable. I have two combo box. Based on the combo selection I’ll check the List’s each items ‘Tag’. If list contains, just i pick that, otherwise i create a new UltraTree and add it to List and i assign to the Tree that is created at design time.

My problem is, what i adding to the collection gets reference and all the item in the collection are overwritten by the last item. UltraTree don’t have any clone method.

I don’t found any way to clone using this control.

What can be my solution 🙁

My sample code is

// My custom class SelectedDeviceState treeState = new SelectedDeviceState(     firstDevice, secondDevice);  UltraTree tree = new UltraTree();  // This will clone the root node // (it will be executed only once -> Root) foreach (UltraTreeNode nod in tvwNavigation.Nodes) {     UltraTreeNode tnode = nod.Clone() as UltraTreeNode;     tree.Nodes.Add(tnode); }  //Adding the custom class as TAG tree.Tag = treeState;  // Assigned and added tvwNavigation = tree; _treeCollection.Add(tree);

You could perform a manual clone by writing a method that creates a new isntance of your type then assigns values to it from the original object.

In terms of a tree structure you would need to write a recursive clone, something like.

private ItemType CloneDeep(ItemType node) {     ItemType clone = new ItemType();     clone.Property1 = node.Property1;     clone.Property2 = node.Property2;      foreach ( ItemType child in node.Nodes)     {         clone.Nodes.add(CloneDeep(child));     }     return clone; } 

Maybe look at extension methods.
