Artboards may contain different objects from different layers... There is no easy way to lock/hide/select all the layers on specific artboard.
It will be a nice Idea to lock/hide/select all layers/objects based on the artboard.
I wish I can do these operation in artboard panel and this feature may lead me to ask why not to Filter Layers by artboard in the Layers panel?!!
