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 switch field is an input field that users use to enter and edit values. If a formula is associated with this property, the switch field is an output field that displays a calculated value derived through the formula.
Referencing switch field values from formulas
When referencing a switch field value from a formula, there is no need to write .Value,Value after the field name if a logical value is sought. These formulas are equivalent:
Above, the AND
function is looking for logical values. As SwitchField1SwitchField1 and SwitchField2SwitchField2 can return logical values
through their Value properties, .Value,Value is implied.
Examples
Returns whether the values of SwitchField1 and SwitchField2 are both TRUE.
Returns whether the values of SwitchField1 and SwitchField2 are both TRUE. Writing out the Value property in formulas (by writing SwitchField1.ValueSwitchField1,Value) is rarely necessary.
This formula is associated with the Visible property of a text box and causes it to be shown only if the switch field ShowMoreInformation is toggled to its "on" position.
