I am using Ignition Perspective. I have a Text Field where the operator enters data. When I navigate to another page/view and then return to the original page, the Text Field value becomes blank (null).
I want the Text Field value to remain unchanged and persist after navigation until the user explicitly clears it using a button.
What is the best way to store and retain the Text Field value in Ignition Perspective ?
Bind the text value to a a custom session property:
Is there more than one session? If so does the data need to be visible to all sessions?
Does there need to be a record of what data was entered?
If it only matters for the current active session, and traceability doesn't matter, @lane.duncan's approach is good.
If multiple sessions need it and you don't need to store that data long term, consider a memory tag.
Otherwise, you might want to consider a database!
Consider session custom props are scoped across multiple browser tabs, if that's of concern
