TrailingUnit property

NumberField.TrailingUnit — Text

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.

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 trailing unit of the field. A trailing unit is displayed after the field value when the value is not being actively edited. It is typically used for units like "kg", "lbs", "m", "in" and "mol". Set the leading unit through the LeadingUnit property.

No space is displayed between the value and the trailing unit. As trailing units should not typically be displayed right next to the value, a space must be manually inserted.


SWITCH(Units, "Customary US", " lbs", "Metric", " kg")SWITCH(Units; "Customary US"; " lbs"; "Metric"; " kg")

Sets the trailing unit to " lbs" if the value of the text drop-down field Units is "Customary US", to " kg" if the value is "Metric" and to a blank value otherwise.
