Listing 1 – XML Editor View

Steps for editing XML File

Even though the functionality of the page is evident from the screenshot, the process of editing the XML file is described below.

The path of the XML file is provided in the XML File Path TextBox. (In the source code, the path ~/App_Data/Book.xml is hardcoded. This file is available in the same directory with the source code.)

Clicking the Load File button will load the TreeView Control with the XML file via an XmlDataSource object.

When the user clicks on a particular node of the TreeView Control, the InnerXML of the node is loaded in the TextBox on the right side.

Now the user can edit the XML as required.

Clicking on the Save Button will save the 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.

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.
