	<!-- Page Content -->
	<p>An example of where you may want to use XML data is within a web service, 
	or to save data to another target besides a database.</p>
	<h2>Typical Goals</h2>
	<p>In this scenario, the goal is to retrieve data from the database and 
	convert it to an XML format.</p>

	<h2>Solution</h2>
	<p>Use the <b>ToXml</b> method provided by the <b>
	EasyObject</b> class to convert the data from the database to an XML string. 
	Use the <b>FromXml </b>method to load the business object from an XML string 
	(typically generated using ToXml).</p>
	<h2>Using ToXml</h2>
	<p>The following code shows how to use the <b>ToXml </b>method.</p>
	<p>[C#]</p>
<!-- code formatted by http://manoli.net/csharpformat/ -->
<pre class="csharpcode">
Products prod = new Products();
prod.LoadAll();

txtDisplay.Text = prod.ToXml();

</pre>
	<p>[VB]</p>
<!-- code formatted by http://manoli.net/csharpformat/ -->
<pre class="csharpcode">
 Dim prod As Products = New Products
prod.LoadAll()

txtDisplay.Text = prod.ToXml()
</pre>
	<h2>Usage Notes</h2>
	<p>The <b>ToXml</b> method does not respect the DataRowState of the 
	EasyObject. If you need to maintain the DataRowState, use the <b>Serialize</b> 
	method instead.</p>
