It depends on the relation of the two Views.

**A.** View2 is Embedded View within View1, OR View2 is a Popup opened by View1:  
Pass the property value as a param to the Embedded View/Popup.

**B.** View2 is on a different Perspective Page than View1:  
Bidirectionally bind the custom property on View1 to a custom session property. Bind the custom property on View2 to the same custom session property.

**C.** View2 is a Docked View of the Perspective Page which contains View1:  
You could still use the session property route, or you could use `system.perspective.sendMessage()` [docs](https://docs.inductiveautomation.com/display/DOC80/system.perspective.sendMessage) as part of a change script on the custom property to broadcast value updates. This would also require a Message Handler be put in place on View2 to listen for the broadcasts.

If you provide a better idea of how the Views will be used, I might be able to help a bit more.
