Target property

GoForwardButton.Target ā€” Screen

Special value available in formulas:

Item

GoForwardButton

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 forward to when the button is pressed.

If this property is not set, the next screen defined for the current screen is shown, if one has been set.

Examples

Makes the button display the next screen defined for the current screen, if one has been set.

ResultScreenResultScreen

Makes the button display the screen ResultScreen.

IF(Verdict = "Success", ResultScreen, WarningScreen)IF(Verdict = "Success"; ResultScreen; WarningScreen)

Makes the button display the screen ResultScreen, but only if the Verdict field is equal to "Success." Otherwise, the screen WarningScreen is displayed instead.

GOFORWARD(IF(Verdict = "Success", ResultScreen, WarningScreen))GOFORWARD(IF(Verdict = "Success"; ResultScreen; WarningScreen))

This formula is associated with the OnPress property of a formula button, and causes the screen ResultScreen to be displayed, but only if the value of the Verdict field is equal to "Success." Otherwise, the screen WarningScreen is displayed instead.
