TreeView: Reusing child node with different parent. 1

[hilmibakhari]

Hi,

I'm creating a preview of a product structure known as Bill of Materials (BOM). In BOM, often a same child is assigned to different multiple parents. I'm intending to use treeview control so that the structure will be clearer.

My problem is that the function that i created to recursively search and rearrange the child node in a treeview will cause exception because i'm trying to place the same child in more than one place.

Please throw some light into this.

Thanks in advance..

Use the TreeNode.Clone method to produce a copy of the node that appears in the tree view at more than one place:

Dim tn As TreeNode = CType(tv.Nodes(0).Clone, TreeNode)

You can then attach the new treenode to the treeview at the required place.

Be aware that cloning a node will also clone all child nodes attached to the cloned node.
