Create a new configuration option so you can not show anything when the value for a field is "null". So, for example; a mobile listview has a new property "shownullvalues", when set to false, it will not display any text when the actual field value is not present (or null).
Hello,
You can use an inline ternary expression to solve this: https://dojo.telerik.com/@iankodj/uCohUSaG.
#: nullValue == null ? "" : nullValue #
