Back button should only work if entries have been saved

Posted on by JanaKH

Hello all,

I am building an app where users are supposed to edit entries. These should of course be saved with the following formula on my save button:
SubmitForm(Detail_Form) & Navigate('Main Screen')

But I also want to create a back button, because sometimes users just want to view the entries and not save something directly. What formula do I need, to make this back button only clickable when the content is already saved/ or nothing was changed?

Also, if the button is not clickable, a text should appear that says "please save first".

In the visibility or displaymode you could use the "form.Unsaved" property which will return 'true' if changes have been made.
If it's visibility, just this will suffice, but if you want it disabled, you'll want something more like

If(Form.Unsaved, DisplayMode.Disabled, DisplayMode.Edit)

Then, just do the "!Form.Unsaved" as the visibility in a text label with "please save first"

^Just make sure to sub in your form's name in these

Hope this helps!

As an additional tip, may I suggest that you put your Navigate action inside the OnSuccess of your Form instead of directly after the SubmitForm action inside your button? This way, you always make sure that the Navigate will only happen if your data is submitted successfully.

Hi @JanaKH,

You can achieve this by following these steps. First, set a variable on the button or icon that enables users to edit the form, like:

Set(AllowNavigation, false)

Then, on your form submit button, update the variable to allow users to navigate using the formula:

Set(AllowNavigation, true)

Finally, add the following logic to your back button:

If(AllowNavigation, Back(), Notify("Please Save The Record Before Navigating"))

This logic will check if the variable "AllowNavigation" is true, and if so, it will navigate back. If the variable is false, it will display a notification asking the user to save the record before navigating.

I hope this helps! Let me know if you have any further questions.
