Use an XMLDataSource to bind to the DevExpress ASPxGridView. However, keep in mind:
The XmlDataSource control is commonly used in read-only data scenarios where a data-bound control displays XML data. However, you can also use the XmlDataSource to edit XML data. Note that automatic update, insert, and delete operations that work with other data source controls will not work.
You must write custom code to modify data using the XmlDataSource control.
