PushButton and Neopixel Strip

Can someone provide an example of the code for this? When you press the button, the strip should turn on. Ive tried over and over but have failed to get it done. I will edit this once I get the code again (I accidentally deleted it) to show you what I did.

Thanks!!

We will wait. Not much use in posting before you had that.
