Dynamic Data Loading
You can bind the XML definition of the survey direct to the Survey Builder Web Control without the need to use physical XML files or even storing the survey in your physical desk. The web control can bind the XML on the fly and load the survey pages, questions, branching rules and media files in the web page without using any physical files.
The sample below bind the survey XML from a local variable and bind the web control.
private string xml = @"<survey version='1.2'>
