Label property
Special value available in formulas:
Item
The button 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. Button1.VisibleButton1,Visible and Item.VisibleItem,Visible are equivalent, for
instance.
The label. If this property is not set, it returns the label set for this button in Calcapp Creator.
Example
Sets the button label to "Reset fields" if all fields of the Field1:Field5Field1:Field5 range are valid and to "Reset invalid fields" otherwise. The Field1:Field5Field1:Field5 range includes the elements Field1, Field5 and all fields that appear between them. (Field1:Field5).Valid(Field1:Field5),Valid returns an array like { TRUE, FALSE, FALSE, TRUE, TRUE }{ TRUE; FALSE; FALSE; TRUE; TRUE }, where each array element indicates whether the corresponding field is valid. COUNTIF((Field1:Field5).Valid, FALSE)COUNTIF((Field1:Field5),Valid; FALSE) returns the number of FALSE elements that are found in the array. Finally, IF returns "invalid " if there are any FALSE elements.
