What are the differences methods Refresh() and Invalidate()?
Click to expand...

Invalidate: "Invalidates a specific region of the control and causes a
paint message to be sent to the control."

Refresh: "Forces the control to invalidate its client area and
immediately redraw itself and any child controls."

So Invalidate (which is asynchronous) lets you specify a certain
region whereas Refresh (which is synchronous) affects the entire
client area.
