I have created several custom Dynamic properties for a Win control. They are
written to .config file. config file is a XML based file. I could edit that
file in a Text Editor and the changed values shows up in the app.

There are functions to read from config file. There are functions in System.configuration
namespace to write to config file. Does anybody know a workaround for this?
I exploring system.xml namespace classed for possible workaround. I am new
to XML.
