Step by step configuration

Introduction

This tutorial will explain how to add, edit, remove nodes from an ASPTreeView control and also how to
update the level of the nodes (after a drag and drop) using obout's latest ASP.NET controls:
ASPTreeView, AJAXPage and Tree_DB.

The AJAXPage web component is used for sending data to the server without reloading the page
and the Tree_DB web component is used to process the data server-side and update the database.

Installing components

First you need to install the ASPTreeView, AJAXPage and Tree_DB ASP.NET controls.
Please take a look at the following pages for more information:
- ASPTreeView
- AJAXPage

Files used

cs_Tree.aspx - this is the main file - here we create an ASPTreeView ASP.NET control and also
a couple of html controls(two buttons - for adding/removing nodes, and two textboxes)
cs_Tree.aspx.cs - the code behind file for cs_Tree.aspx - it is used to load the treeview
from a database (an SQLEXPRESS database in our example - TreeNodes.mdf)
cs_TreeEvents.aspx - the data will be sent to this page for processing
cs_TreeEvents.aspx.cs - the code behind file for cs_TreeEvents.aspx - here we make all the
server-side processing
cs_TestConnection.aspx - page for testing if the connection is set up correctly
cs_TestConnection.aspx.cs - the code behind file for cs_TestConnection.aspx
TreeNodes.mdf- the SQLEXPRESS database containing the information about the ASPTreeView's nodes

Client Side Server Side

"Your TreeView component with the use of the Tree DB component are a real winner. I am using this with my CMS applications that allow the user to order the documents with a simple drag and drop. It's brilliant and my clients now have a more intuitive application."
