Epilogue 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 text that appears after field values in an attached file. The Prologue property represents the text that appears before field values.
If this property is not set, no epilogue is used.
Entering formulas in the inspector
If you use the inspector to enter a value for this property, you can
incorporate formulas by enclosing them within {{ and
}} markers.
Behind the scenes, Calcapp converts an inspector value with formulas to a single traditional formula. You can view this formula, or edit it directly, by selecting the Epilogue property from the drop-down menu next to the formula bar.
The examples on this page use traditional formulas, where text strings and
other values are joined together using & and line breaks are produced
using NEWLINE. To
enter them in the inspector, be sure to enclose them within {{
and }} markers. Alternatively, enter them in the formula bar.
Refer to the documentation for the Body property for a complex example on how to produce a text string incorporating field values using a formula.
Example
temperature readings above!")IF(CriticalTemperature > 86; "Look closely at the
temperature readings above!")
Sets the text that appears after field values to "Look closely at the temperature readings above!" only if the value of the CriticalTemperature field is greater than 86.
