Posted 10 September 2017, 11:39 am ESTHello.
I classify each node in the client side to avoid certain actions, such as "Drag & Drop."
On the server side I assign to each node an attribute name and value, for example:
treeNodeAux.Attributes.Add ("NyName", "MyValue");
But the properties are lost in each postback.
I can do to not be lost or other property of the class "C1TreeViewNode" I can use to see what type is my node.
