Adding Data to TreeView Nodes

Woinowski · #1 (**permalink**) 08-23-2007, 07:07 AM

Hi,

I'd like to be able to add data (a string, number or even arbitrary variable type) to each tree node.

As an example: imagine a notepad with a tree structure (there's a lot of those out there, just an example).

You would be able to navigate through the tree to your notes and each node could contain a note(text string).

Currently, I can only think of awkward workarounds (e.g., simulating a tree with the same structure in an ArrayList).

Just using the Node.Text member is not the correct idea: In the tree view I would only want to show titles of the notes/nodes.

To make my idea clear:

In visual studio the TreeView-Node Class has a member "Tag" for user defined data (in C#) That's just what I am looking for....

The Tag property of .Net Framework controls is only available on the full framework (not .Net CF).

And it is not possible to add something similar, even a simple string tag, to the B4PPC library Node class?

It is possible to add it and I think we will add it.

Cool. I'm looking forward to that. Currently I have found a workaround:

I use a tree without images. The image index can be used to reference an item in an arraylist :-)

Nice solution
