title: Representing hierarchical data using a DataGrid/GridView control
body: <p>I do not have access to third party components on this project. I think I only have access to the built-in DataGrid and GridView controls.</p>
  
  <p>Is there a good example for representing hierarchical data (inside a grid - Master /Details) in a built-in ASP.NET server control?</p>
  
  <p>I am looking for an expand/collapse tree structure kind of implementation.</p>
