Introduction

This article explains how to use the ASP.NET TreeView control to edit an XML file which resides on the same server. The origin of this article starts when there was a demand from the end users to create an Admin section to edit a configuration XML file for an internal ASP.NET application. The functionalities of the application were completely configurable and the configuration values were kept in this particular XML file. To edit this XML file, the admins had to login in to the server which hosted the application and edit the XML file using a text editor which was tedious.

After some research I developed a control panel for the application which uses TreeView Control and a TextBox control to edit the configuration XML File.

Chetan,

Moving nodes using the UI is not possible. While you are editing the nodes in the textbox on the rightside, if you move nodes from one place to another and save it, the tre view on the UI will reflect the same and will move the node to the new position.
Basically it shows the same position of the node in the XML document.

Hi Nishanth,

Nirdesh,
Since we are editing the XML file, the file must be within the virtual directory. Otherwise the asp.net worker process will not have permission to edit files outside the virtual directory. In this example, the XML file is a data/config file of the web application which is inside the Virtual directory.

One thing you can do is to upload the XML file from the client, download it in a temp directory, edit it and then make it available for the user to download. Feel free to modify my code and implement in a more user friendly way!!

This is very good example. But its required little change. 1) It have to take files from outside the project.
2) It should be browse the files also and select.
