Question
Using the Form Designer, is it possible to make a field hidden based on the numeric value of another field? For example, if I want to make a field visible only if a numeric value in a previous field is greater than 3?
Solution
In the form field Settings / Validation / Custom, check if the field value is not null or empty then apply a String to Int conversion in the condition, since the condition is a C# language instruction.
!String.IsNullOrEmpty(REQUEST_NUMERIC1.Text) System.Convert.ToInt32(REQUEST_NUMERIC1.Text) > 3
