I would like to be able to use an XML file to initialize the structure of the grid, but not the data. Properties such as the number of columns, datatypes, etc., would be defined in the XML file, but I want to be able to load and refresh the data from the database, directly. Is this possible? If so, how?

There is no way to connect directly to DB buy you can use same loadXML command with dynamic server side script

In such scenario component will try to load data from server side script, which will connect to DB and output necessary data as XML.
