Hi Imar,

Great book, BTW.

I'm looking for the simplest path to binding the Nav Data to an XmlDataSource (..ObjectDataSource?) to serve to treeview/menu controls, vs. the current two repeaters in the SiteMenu.ascx.

I've created a (mostly) functional example with a relational dataset bound to XmlDataSource, transformed via .xsl file. It's probably more complicated than it needs to be- and xsl is still quite foreign to me.

Might you have any suggestions/overview of the most logical way to do this?

FWIW- I'm also thinking that a single, self-referencing table to store ContentType/Category data.. along with appropriate business/presentation mods, could provide unlimited category levels. Ultimately, I'll rewrite friendly urls.. (which I'm surprised nobody has mentioned yet)

Your comments would be greatly appreciated!

Hi there,

You have a few options. One is to stick with the XSL file. I am not too good with XSL to I can't recommend much to improve your code.

Alternatively, you can use the SiteMap file and provider. This control displays hierarchical data by default. You could write a physical copy of the site map whenever you make a change in the categories in the system.

Finally, you can indeed use a relational dataset with a self referencing column. You could write a recursive method that loops through this dataset and manually adds nodes to the TreeView at the requested level. I have done that a while ago, so I can assist you with it if you need some help.

Cheers,

Imar

Hi Imar

I realize this post is quite old but i am interested in setting up a self referencing table to allow for unlimited categories. If you could provide me an example or a starting place on how to setup the recursive method for the treeview and any other help would be most appreciated.

Thanks again and great book btw!

Hi Adam,

I haven't tested the code in this article, but it looks like it does what you need: http://www.codeproject.com/aspnet/Au...ngTreeView.asp

If you need more help, let me know. I don't have the time right now to dig up the old code I was referring to (can't even recall where I used it, to be honest...

Imar
