Removing a row from 2 databases

[Anonymous]

Hello!

I am using a formula to delete a ticket from my database and then also delete an image from another database. The formula I am using for this: 

Remove([@'Foto''s Manco App'], LookUp('Foto''s Manco App',Title = DataCardValue12.Text & " " & DataCardValue24.Text));

Remove(
    [@'Manco-Informatie'],
    OverzichtGallery.Selected
);

If (
    IsEmpty(
        Errors(
            [@'Manco-Informatie'],
            OverzichtGallery.Selected
        )
    ),
    Back()
) && UpdateContext({Popup: false})

Whenever I use the code like this, only the second remove works. When I remove the bottom part and only put the top remove part, the top code works. 

What am I doing wrong here?

I don't know why this would happen. It is very strange. However, I did notice an improvement in the code, which might work.

Remove([@'Foto''s Manco App'], LookUp('Foto''s Manco App',Title = DataCardValue12.Text & " " & DataCardValue24.Text));

Remove(
    [@'Manco-Informatie'],
    OverzichtGallery.Selected
);

If (
    IsEmpty(
        Errors(
            [@'Manco-Informatie'],
            OverzichtGallery.Selected
        )
    ),
    Concurrent(Back(), UpdateContext({Popup: false}))
);

Hi @Anonymous ,

Do you mean that the remove function will only work one?

That's a little strange...

Could you tell me

1)where do you put this formula?

2)the relationship between the form and OverzichtGallery.Selected

3)the screenshoot of your app?

Please notice one thing:
if the form is updated, the data in the form will become invalid. In your issue, DataCardValue12.Text and DataCardValue24.Text will become invalid after you submit the form. So if this formula is related to the form's updating, you need to firstly save DataCardValue12.Text and DataCardValue24.Text  as variables before update the form. Then after you update the form, you could use these two variables in your other formulas.

Since I do not know your app's logic very clearly, I could not give you detailed solution.

Maybe you could try Concurrent function, which will evaluate multiple formulas at the same time.

Concurrent(
Remove([@'Foto''s Manco App'], LookUp('Foto''s Manco App',Title = DataCardValue12.Text & " " & DataCardValue24.Text)),
Remove(
    [@'Manco-Informatie'],
    OverzichtGallery.Selected
)
);

If (
    IsEmpty(
        Errors(
            [@'Manco-Informatie'],
            OverzichtGallery.Selected
        )
    ),
    Back()
) && UpdateContext({Popup: false})

Best regards,

That has done it, thank you! @v-yutliu-msft

@v-yutliu-msft  When I use this formula and have multiple rows, it doesn't work. I can have multiple rows with the same name, how can I make it remove every row for this formula:

Remove([@'Foto''s Manco App'], LookUp('Foto''s Manco App',Title = DataCardValue12.Text & " " & DataCardValue24.Text)),

Full code:

Concurrent(
Remove([@'Foto''s Manco App'], LookUp('Foto''s Manco App',Title = DataCardValue12.Text & " " & DataCardValue24.Text)),
Remove(
    [@'Manco-Informatie'],
    OverzichtGallery.Selected
)
);

If (
    IsEmpty(
        Errors(
            [@'Manco-Informatie'],
            OverzichtGallery.Selected
        )
    ),
    Back()
) && UpdateContext({Popup: false})

LookUp returns the first matching row only. You can use RemoveIf to remove all matching rows. 

RemoveIf([@'Foto''s Manco App'], Title = DataCardValue12.Text & " " & DataCardValue24.Text)

You can also use filter which will return all matching rows. 

Remove([@'Foto''s Manco App'], Filter([@'Foto''s Manco App'], Title = DataCardValue12.Text & " " & DataCardValue24.Text))
