Question

Is there a way to hide a column in Lotus Notes if the entire column is empty? I’ve tried using

@ThisValue = ""

in the column properties, but that causes the column to disappear if atleast one value is null, rather than if all the values are null.

Answer 1

Put the code to check emptiness of the column into view’s QueryOpen handler. Depending on the result of your check set a value (f.e. “0” or “1”) to an environment variable:

Call notesSession.SetEnvironmentVar("hidecolumn", "1")

or

@SetEnvironment("hidecolumn"; "1")

And in your column’s hide-when formula write @Environment("hidecolumn") = "1"

It works in LN6.x and later.
