how can add , edit, delete nodes and sub nodes in treeview in vb.net 2005 and sql server2005
Normal TreeView does not allow it. You should use a custom TreeView provided here
http://www.codeproject.com/Articles/43057/ASTreeView-Free-ASP-NET-TreeView-Control
any thing else because i want admin can add edit and delete nodes snd subnodes on the display page
Unfortunately there isn't. Then you will have to buy Rad Control TreeView with more features
Else what you can do is for admin use this treeview (for add edit delete) and for other users use the normal TreeView
