How to use TreeView control in ASP.NET 2.0

Introduction to TreeView Control
ASP.Net 2.0 introduces many new controls including a TreeView Control,
which can be used to consume information from hierarchical data
sources like an XML file and then display that information. In this
tutorial, I am going to statically data bind the TreeView control with
the contents of an XML file.

Working the Code: TreeView Control Example
Create a new web application, and open the Default.aspx page in design
view. Locate the TreeView control in the toolbox and drag it onto the
form. Here is what it looks like by default:

Click on the small box located in the upper right-hand corner of the
control, choose Auto Format, and select Contacts style:

This will update the control to look like the above. There are many
pre-defined formats for you to choose from, take a few moments to look
at each of them.

The next step is to add a new XML file to the project and create your data file:

<?xml version="1.0" encoding="utf-8" ?>

<Contacts>
<Contact Name="Salman Khalid">
<Description Value="Phone#, EMail Address, Web-Site">
</Description>
</Contact>
<Contact Name="Salman 2">
<Description Value="Phone#, EMail Address, Web-Site">
</Description>
</Contact>
<Contact Name="Salman 3">
<Description Value="Phone#, EMail Address, Web-Site">
</Description>
</Contact>

</Contacts>

Switch back to Default.aspx and add an XMLDataSource object to the
form. Set its DataFile to the new XML file. Select the
TreeViewControl, and set it's DataSourceID to the XMLDataSource
object.

Select the DataBindings property and open the TreeView DataBindings
Editor. It will automatically have loaded the nodes. Select
"Description" and click ADD. Set ValueField to Value. (Note: you can
set value field and display field separately. Like for instance, you
could display Client Names, but set the node's value equal to their
ID.)

Click on Apply and exit the Editor. Switch to the XML file and set
some real-time entries, and run the application.

That's all there is to it. Simple and clear... now switch back to the
Default.aspx page and open the TreeView DataBindings Editor again.
This time add databinding settings for the Contact nodes.

Save and run the application again.

Change the values in the XML file, and refresh your web-page to see
the changes in the tree.
