Thank you for your feedback. Unfortunately, even though it is populated from database, it is assigned into each node one by one. This behavior is unbound behavior. So, you could not add, edit and delete on WebTreeView.

It would be good to publish a couple of examples based on database that is helpful not only work with XML files is very static .

I have tested and it is a minor bug in our WebTreeView. I have forwarded this to our developer with #406 WI number and they will fix it in our next release.

I have just found some way how to populate database via dataset. By populate database in each nodes, it would be similar with WebTreeView unbound. Attached sample is my sample. Hope this helps you.

please let me know how can i populate the tree using the database value. (here i am using oracle)

the values of the tree and its child nodes are in the different tables of the database with some relations.

thanking you
