I have created multiple views in Ignition perspective. Now I want to pass datetime value selected by user (ViewA) that I want to cascade to another view (ViewB). How can I achieve this?

Create a session variable to hold the date.

- In _Project Browser_ select _Perspective_.
- In _Perspective Property Editor | SESSION CUSTOM_ click _Add Custom Property_. Create your variable. e.g. `sessStartDate`.
- On the _Datetime_ component bind the _value_ property to the session variable. Set the binding as "Bidirectional" so that the variable is updated by the selection.

On any views that need the date it is now available in the session variable.

In general, this is how to create a global scope variable in Perspective.
