Hi, thank you for your fast answer!
It is working good but I have another problem:
TreeNodeAdvExt cnode = new TreeNodeAdvExt();
cnode.Text = "xxxxx";
cnode.Name = "cnode1";
//it is ok
treeNodeAdvExt1.Nodes[0].Nodes.Add(cnode);
//but it is not working - obviously. Regular TreeView supports this.
treeNodeAdvExt1.Nodes["Node 4"].Nodes.Add(cnode);
I can search by name but I have large trees (100 000+ nodes, including a multicolumn). I think search won't be too efficient.
