Exception when re-adding nodes

[Michael]

The following code will reproduce the exception:

RadTreeView tree = new RadTreeView();
tree.Name = "tree";

RadTreeNode[] nodes = new RadTreeNode[5];
for (int i = 0; i < nodes.Length; ++i)
  nodes[i] = new RadTreeNode(i.ToString());

tree.Nodes.AddRange(nodes);
tree.Nodes.Clear();
tree.Nodes.AddRange(nodes);

It seems that I would need to call "Remove" on each node before adding them back to the tree. But, since I'm adding them to the same TreeView, should an exception still be thrown?

Hello Liru,

Thank you for writing.

Indeed, I can confirm that the exception is thrown in this case. I am logging this in PITS and we will address it accordingly. Feel free to subscribe for its status updates at the following link:  http://www.telerik.com/support/pits.aspx#/public/winforms/11737.

As workaround, you can call the Remove method the each node, as you mentioned.

Thank you for this report. Your Telerik points have been updated accordingly.
 
All the best,
Stefan
