minesweeper

i wanna make my own minesweeper game, using c#, how do i do the visual part, the button, if i use like 400 buttons it takes time to draw them all, how does the original game make the more than 500 buttons immediately?

a loop? i use one to make the buttons.
but if i make like 144 buttons it takes a few second to draw them all,  the original game makes 667 in no time, how?
sorry if i misunderstood u, in that case can u explain a little bit more.
