asp.net organize data in folders
<p>I have a requirement in an ASP.NET 4.0 application to organize a list of tasks into folders. The folders are nested and can have a depth of up to 20 levels. Each task can be assigned to a folder at any level,
I look at treeview control but no way to dynamically add/delete nodes.</p>

<p>Any Ideas</p>

<p>thanks</p>
