Value property
Special value available in formulas:
Item
The field this property is part of, enabling multiple checked items in the app designer to share the same formula and be updated all at once.
Consider the fields Field1 and Field2, which should
only be considered to be valid if their values are
greater than 4. Without using the Item value, the Valid
property of Field1 would need to use the formula Field1 > 4Field1 > 4 and the Valid
property of Field2 would need to use the formula Field2 > 4Field2 > 4.
Using Item, both formulas can read Item > 4Item > 4. This is useful
if you have many fields and you want to be able to update their
formulas all at once. To do so, click their check boxes in Calcapp
Creator and make sure that a checked field is selected. Then, when you
update a formula for one checked field, you update all the other
checked fields too, which is a great timesaver.
Use Item in exactly the same way you'd use the regular
name. Field1.VisibleField1,Visible and Item.VisibleItem,Visible are equivalent, for
instance.
The value of the field. If no formula is associated with this property, the number field is an input field that users use to enter and edit values. If a formula is associated with this property, the number field is an output field that displays a calculated value derived through the formula.
Referencing number field values from formulas
When referencing a number field value from a formula, there is no need to write .Value,Value after the field name if a number is sought. These formulas are equivalent:
Above, + is looking to add two numbers together. As NumberField1NumberField1 can return a number through its Value property, .Value,Value is implied.
