title: winforms save datatable locally
body: <p>In my application, I load a small datatable from a database and use the datatable  to bind a column to a combobox dropdownlist.</p>
  
  <p>Everytime the combobox is shown, ibelieve it pulls data from the database which seems unnecessary as the data hardly every changes.</p>
  
  <p>Is there a way to load the datatable once in memory when the application opens and then use it over and over in a form? </p>
  
  <p>Please explain the basic mechanics of how this would work.</p>
