Special value available in formulas:
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.
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.
Item in exactly the same way you'd use the regular
name. Field1.VisibleField1,Visible and Item.VisibleItem,Visible are equivalent, for
The initial value, displayed before the user has entered an explicit value.
An unchanging initial value can be assigned to a number drop-down field simply by selecting a value from it in Calcapp Creator. Select the empty value to unset the initial value.
If an initial value is set through a formula, the formula is evaluated just before the screen housing the field is shown. In other words, the formula can reference values of fields that have been shown previously.
Sets the initial value to the value of the Result field, which appears as part of the screen MainScreen, but only if it is greater than 4. Otherwise, the initial value is set to 0. The value of the Result field must be among the options supported by the number drop-down field.
