In c# win forms how do I scroll over hundreds of items

Is there a common design for allowing the user to scroll over hundreds or
thousands of items in a windows forms container? Example: writing an email
client, the user gets the impression of smoothly scrolling over 10,000
message "rows," one for each email - but those surely are not really
rendered until just before they are displayed. Similarly, scrolling over a
huge image must require tiling it in smaller pieces, but how is the code
organized that presents that?
