title: IEnumerable to gridView
body: <p>I am creating a gridview and need to gather the data from various functions that return a type of IEnumerable. </p>
  
  <p>I've created gridviews using a dataset as a datasource, but how does one use multiple data sources(of IEnumerable) to populate one gridview?  Like how do you combine all that into one dataset?</p>
  
  <p>Thanks</p>
