I am using RadTreeView in my project.the hierarchy is as below.
- In Master page on Left hand side i am having the treeview.on right hand side having contentpages displaying the information related to the seleted node.
- In TreeNode from context menu will go and add the records dynamically.when want to add the newnode clicks add from the context menu then the node is added and related content page is displayed on right hand side will fill the details and click on save then the node gets saved in DB.
- Maintaining the state of the treeview in session by using getXml(),and setXml() of the treeview.
- As of now in our treeview there is drag and drop functionality the end user will drag and drop the nodes from one parent to another parent and so on......and when clicks on save then only need to update the relations in the DB.how can i maintain the changes done by the user by drag and droping until they clicks on save.what nodes has been changed what nodes to be updated in the database.
