Solved: How to code last submit in a dropdown?

RoB-E · ‎09-21-2022

I'm new to power apps and just trying to code a drop down to return last submittedvalue on newform not sure how to and help would be much appreciated. The app I'm working on will create 20 to 30 records a day with the same block number. So I need the dropdown value to defualt to last selected value when submitted on new form

Yes try like this.

Presuming a Form called Form1 and a button called Button1 and a data source called List01 (such as a SharePoint List, for example):

Form1 DefaultMode

FormMode.New

Form1 Item

If(!IsBlank(First(Coll_Last_Submit)),First(Coll_Last_Submit),Defaults(List01))
//Instead of List01 above, use the name of your SharePoint List or data source.

Form1 OnSuccess

Clear(Coll_Last_Submit);Collect(Coll_Last_Submit,Form1.LastSubmit);Patch(Coll_Last_Submit,First(Coll_Last_Submit),{ID:Blank()})

or

ClearCollect(Coll_Last_Submit,Form1.LastSubmit);Patch(Coll_Last_Submit,First(Coll_Last_Submit),{ID:Blank()})

Button1 OnSelect

SubmitForm(Form1);

This should work, and the New form after submit, will have all the previous values based on the last submitted record, but still be a new form mode. After the next submit, it should create a brand new record.

If the above does not work, properly i.e. for example, if for some reason it just keeps editing the same last submitted record over and over again, it could be because the part where Patch of Blank() value for ID, might not work and not actually remove the ID (thus editing the same last submitted record over and over again), unless a specific setting is turned on in the app called Formula-level error management . So if it does not work, try these steps as well below first:

1. Click on Settings

2. In the modal, click on Upcoming Features -> Preview -> Formula-level error management - set this toggle, to "On"

3. Close this modal.

4. Save and Publish the app.

5. Close the whole Power Apps editor.

6. Go to make.powerapps.com, select the right environment, find your app for editing, and open it up for editing. If you just made this app recently and it's missing from the list for some reason, just try making a new blank app, and the one that is missing might now appear in the list.

7. Try the app now and see if it works.

This setting has been around for quite a long time, it is often turned on for this kind of scenario, the fact that it is labeled "Preview" may not be so much of a concern, I doubt the feature is going away in the future. While that is technically subject to change, I am not able to think of a better way to accomplish your scenario. First try and see if it works with the Formula-level error management setting off (the default). If it does, then great. If it does not (and I suspect that it might not), this setting Formula-level error management may have to be set to On for this solution to work properly. Please note that after turning it on, it may be necessary to close and reopen the app for editing as stated in the above steps, if it is still not making a new record on each submit, so that the setting could fully take effect.

See if it helps @RoB-E

@RoB-E

You can try to use Blank() for Default instead of "" to be more accurate - especially since you may already be using Blank() now in the Patch statement I gave to make the ID field blank in the new record after submit.

It may be required to have Formula-level error management turned on as I mentioned before, to use Blank() values (especially to patch out the ID to a Blank value).

If it is working better or more consistently for you with "", or if you just prefer it, then using "" for Default may be acceptable as well. I recommend to use Blank() but if you prefer it, you may use "" instead, but make sure to carefully test it, some cases may require Blank() to be there and not "" to signify a blank value for a field.

If the button is pressed again and again, it will create new records with the same values, this is by design of what you requested. They definitely should be different records though with a different unique ID if you check the SharePoint List.

If you want one or more fields to always be different, try using a function like Rand(). You could also try accessing the LastSubmit directly after the OnSuccess, getting the unique ID, and Patching it to another field - although I am unsure why that would be a good idea - the unique value is already there generated automatically, it may be better to simply edit the SharePoint List view, reveal the unique ID, and notice they really aren't "duplicates".

Whatever makes it look like a "duplicate", you could perhaps blank out more fields such as specific fields that should not be pre-filled for instance.

Change

ClearCollect(Coll_Last_Submit,Form1.LastSubmit);Patch(Coll_Last_Submit,First(Coll_Last_Submit),{ID:Blank()})

to

//pseudocode
ClearCollect(Coll_Last_Submit,Form1.LastSubmit);Patch(Coll_Last_Submit,First(Coll_Last_Submit),{ID:Blank(),SomeOtherFieldToBlankOut:Blank(),YetAnotherFieldToBlankOut:Blank()})
//change "SomeOtherFieldToBlankOut" and "YetAnotherFieldToBlankOut" to what makes sense for you for what you want to not use the last submitted value, but be blank instead, and have how many or how few of those you want.

You can test by using Rand() which should make it pretty obvious they're not duplicates, then try instead to do whatever makes more sense for the field(s) instead.

In case there may still be some issue, could you clarify what you mean by noticing that you have duplicates?

Could you check if LastSubmit - docs.microsoft.com could achieve your goals?

LastSubmit – The last successfully submitted record, including any server generated fields.
This property applies only to the Edit form control.
If the data source automatically generates or calculates any fields, such as an ID field with a unique number, the LastSubmit property will have this new value after SubmitForm successfully runs.
The value of this property is available in the OnSuccess formula.

In your Save or Submit button, add this code.

ClearCollect(ColLastItem, Submitform(FormName));

Like @poweractivate mentioned, you can also try Formname.LastSubmit

Ok so my save button onselect has this code: SubmitForm(EditForm1)ResetForm(EditForm1)NewForm(EditForm1) do I add it to the end or beginning of this ?

SudeepGhatakNZ · ‎09-21-2022

ClearCollect(ColLastItem, Submitform(EditForm1));ResetForm(EditForm1);NewForm(EditForm1)

So if my last submission dropdown was say 205 it would still be 205 on the newform after submit?

SudeepGhatakNZ · ‎09-21-2022

Your Newform won't have an ID until the form is submitted back again.

SubmitForm will only return the ID of the record that it just submitted

Ok so I'm a bit confused? I need the newform to show the submitted forms value in the drop down. So if I submit a value of 203 I need the newform to show that last submitted value

RoB-E · ‎09-21-2022

I tried the formula and it had no errors but it did not return the dropdown to my last selected value. Is there away to make that happen?

SudeepGhatakNZ · ‎09-21-2022

What value did it return in ColLastItem? Are you able to check that by adding a label and setting its text property to ColLastItem? Just so that we are clear, ColLastItem will return you ID of the new record created in SharePoint List.

In case I am not following you, a screenshot might help
