How to bind ASPxGridView with XmlDataSource

This demo is based on the GridView Examples for ASP.NET 2.0: Accessing Data with the DataSource Controls MSDN article. It illustrates how to bind the ASPxGridView with the XmlDataSource control.
The ASPxGridView generates its column automatically for the following XmlDataSource's structure:

[XML]
<root><DataItemfield1="...".../></root>

[ASPx]
<dx:GridViewDataTextColumnFieldName="field1"/>

If it's necessary to bind the ASPxGridView with the XmlDataSource whose structure is non-standard:

[XML]
<root><DataItem><field1>...</field1></DataItem></root>

1) Use the XSLT technology to transform the underlying XML file in the required manner:

[XML]
<?xmlversion="1.0"encoding="utf-8"?><xsl:stylesheetversion="1.0"xmlns:xsl="http://www.w3.org/1999/XSL/Transform"><xsl:templatematch="/"><items><xsl:for-eachselect="//DataItem"><itemfield1="{field1}"/></xsl:for-each></items></xsl:template></xsl:stylesheet>

2) Use the GridViewColumn's DataItemTemplate and an XPath expression:

[ASPx]
<dx:GridViewDataTextColumnFieldName="field1"><DataItemTemplate><%#XPath("field1")%></DataItemTemplate></dx:GridViewDataTextColumn>

To allow ASPxGridView sorting, it's necessary to implement the IXPathNavigable interface for the ASPxGridView.DataSource's type. Please refer to the XPath Querying Over Objects with ObjectXPathNavigator MSDN article regarding this.
