Hi everyone,

I have a linq query with the needed results abd need to display the results using a treeview, but the treeview needs IHierarchicaldDataSource or IHierarchicalEnumerable.

Here is my linq code:

var roles = from r in db.aspnet_Roles

select new {r.RoleName};

How can I populate the treeview in codebehind, without usin linqdatasorce?

Thank's a lot,

/Pepe

Hi,

Use linq to populate a treeview just like populate the treeview from the database.

About how to populate a treeview from the database, you can refer this codeproject article: http://www.codeproject.com/KB/tree/TreeViewWithDatabase.aspx

You can also refer this article, it talks how to populate menu from database, but it give to some good suggestion: http://aspalliance.com/822

Hope it helps.
