edit form submission on unique items

[joef]

Hi All,

Happy Holidays!!!

I have an App on top of an SPO list.  I set the Item number to be unique in the list.  I have an error in the app if you try to submit a duplicate item number.

I set my edit button to only be visible for items added today.  but if I go to edit an existing item, I get the duplication error and I can not submit the form.

how do I differentiate between an update to an existing as opposed to adding a new item?

Thanks,

Joe

The way to differentiate between inserting a new row and updating an existing row are the NEWFORM and EDIT form functons respectively. Typically you would use these functions in the OnSelect property of a button used to navigate to the Form.

NewForm(your_form_name);Navigate(your_screen_name);

EditForm(your_form_name);Navigate(your_screen_name);

Hi @mdevaney ,

I hit send too soon, I left out the code that is stopping me from continuing...

on the submit button, I check to make sure the location number = the 1st 3 digits of deposit number, then I check to see if the item is in the list.  Is there a way to check if I am editing before checking?

If(
LocationValue.Text <> Left(DepoNumberValue.Text,3),
Notify("The Location you entered does not match the deposit slip number, please make sure your location is 3 digits and match the first 3 digits of the deposit slip number and try again", NotificationType.Warning),
IsBlank(
LookUp('Edison Deposit Entry', 'Deposit Slip Number' = DepoNumberValue.Text).'Deposit Slip Number'
),
// If its blank then there's no existing value with that same value so submit

SubmitForm(EditForm1)
,
// If its not blank then let the user know and switch focus to that field
Notify("The deposit slip you entered is already in the system, please check your number and try again", NotificationType.Warning);
SetFocus(DepoNumberValue)
)

Thanks again,

Joe

Yes, of course.  We can check if the FormMode is Edit using a logical statement.

Form1.Mode=FormMode.Edit

It can be used within an IF statement like this

If(Form1.Mode=FormMode.Edit, some_code_true, some_code_false)
