Lock for Sliding Gate

I've just installed a new cedar privacy fence around the perimeter of my backyard with a top-mounted sliding gate. Right now, when the gate is closed, I secure the bottom to the side posts on either end with simple hook-and-eye hardware. I'd like something less provisional and more secure. I want to be able to lock the gate closed, but I can't find the right hardware online so far. Slide bolts appropriate for swinging gates would be ineffectual for my sliding one, and I can't figure out how to search for a slide bolt that can turn and catch so as not to secure the gate laterally. I'm trying to avoid the hassle of a drop bolt or cane bolt into the ground. Surely, there's a simple solution?

If anyone has experience with a similar scenario, I'd be grateful for guidance!

 

A photo of the gate closed showing where you want to place the lock would be helpful.

All help much appreciated!

 

Are you wanting to be able to unlock it from both sides or just one?

Here is one that would work for one side, but not sure if it's what you are looking for;

Thanks for the idea and the link, HotinOKC!

Locking from inside and outside the gate isn't an absolute necessity. The spring action stall and gate latch is close to what I need, but it wouldn't suit the gate because my sliding gate meets the vertical frame post in the middle of the post. In other words, the surface of the gate panel and the post are not flush with each other, as needed for the installation of this lock.
