Target property

GoBackButton.Target — Screen

Special value available in formulas:

Item

GoBackButton

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 screen that the user is moved backward to when the button is pressed.

If this property is not set, the user is moved backward exactly one screen, if possible. If the screen returned from this property is not a screen that has been previously visited, nothing happens.

Examples

MainScreenMainScreen

Makes the button move the user back to the screen MainScreen. If that screen has not been visited previously, nothing happens.

IF(Verdict = "Success", MainScreen, DetailsScreen)IF(Verdict = "Success"; MainScreen; DetailsScreen)

Makes the button move the user back to the screen MainScreen, but only if the Verdict field is equal to "Success." Otherwise, the user is moved back to the screen DetailsScreen.

This formula is associated with the OnPress property of a formula button, and moves the user backward exactly one screen, if possible.

GOBACK(IF(Verdict = "Success", MainScreen, DetailsScreen))GOBACK(IF(Verdict = "Success"; MainScreen; DetailsScreen))

This formula is associated with the OnPress property of a formula button, and moves the user back to the screen MainScreen, but only if the value of the Verdict field is equal to "Success." Otherwise, the user is moved back to the screen DetailsScreen.
