Do you want to go to previous view or previous display state.
To go back previous state you can use "Isolate" while locating the part (selecting parts which you want to be seen and hiding others) and then say "exit isolate" to show rest of the parts again.
To isolate, keep ctrl button pressed, select parts you wish to be seen, and right click then select Isolate
After completion you can select "Exit Isolate".
You can add a mate in one config and suppress that mate for another config which would make you freely drag the part.
You may also want to check the alternate vie if you're looking to show different positions of a component in drawing.
Display States in its self cannot be used to show varying positions of components in an assembly.
As Deepak advised; "configurations" provide for this capability and alternate drawing views are supported using configurations as well.
If you are looking at different placements for components, you can use mate commands
...then simply undo to get back to original positions
...or "Use for positioning only"
As Mr. Gupta suggests, use configurations.
If positions aren't restored when you return to the original config, that probably means the orientation/position wasn't defined enough and when the second config moved things, there weren't any/enough fist config mates to restore the original expectations.
For example , if two faces are abutting, but are not constrained so, a second config mates one of these faces to something else, those faces obey.
When you restore the first config, the mate for the second config is suppressed, but there's nothing in the first config to move thes pieces back together.
Check to see if your original state is fully mated.
