Field in Power App is not reset to Parent.Default without manually refreshing

(0) ShareShare
ReportReport
Posted on by DJanssen 427

Hello, 

I have a text field in my Power App form that looks like this:

DJanssen_1-1706684628070.png

Default property:

If(
 !IsBlank(ExistingDocumentNumbersDropdownValue.Selected.'Doc Reference'),
 ExistingDocumentNumbersDropdownValue.Selected.'Doc Reference',
 If(
 !IsBlank(LastSubmittedCode), 
 LastSubmittedCode,
 Parent.Default
 )
)

When clicking on Create Document Number the user will be navigated to a second screen where the Document Number will be generated and set in a variable:

Set(LastSubmittedCode, GeneratedDocumentNumber.Text);

However this lead to the following behaviour; if I upload 2 documents and assign a document number to the first document that same document number will be shown as LastSubmittedCode when I open the properties of the second document. This only goes away by manually refreshing, but this will confuse users and I want to this field to basically default to Parent.Default (which is empty standard) when opening the Power App on any new document.

I tried to add this to the OnVisible property of my Mainscreen:

Refresh('IMS Working Area');

But this does not resolve the error.

    Hi @DJanssen ,

    Firstly you can condense that to 

    Coalesce(
 ExistingDocumentNumbersDropdownValue.Selected.'Doc Reference',
 LastSubmittedCode,
 Parent.Default
)

    but you need to reset the control if you want it to refresh the data.

    Hi @WarrenBelz ,

     

    Thanks for your suggestion. That looks a lot shorter and better readability. A question regarding the resetting of the form. Currently the DocumentNumberTextValue has the following Reset property:

    DJanssen_0-1706687167078.png

    Do I simply need to set this to true?

    hey @DJanssen 

     

    you can also try this:

    // Assuming this is your button's OnSelect property
ClearCollect(
 GeneratedDocumentNumberCollection, // Create a collection to hold the generated document number
 {
 DocumentNumber: GeneratedDocumentNumber.Text
 }
);

Set(LastSubmittedCode, First(GeneratedDocumentNumberCollection).DocumentNumber);

Navigate(SecondScreen, ScreenTransition.None);

     

    Let me know if my answer helped solving your issue.

    If it did please accept as solution and give it a thumbs up so we can help others in the community.

    @DJanssen ,

    Easiest way is to set the Reset property to a Variable (example varReset ) then use a Global Variable if you are switching screens

    . . . . .
Set(
 LastSubmittedCode, 
 First(GeneratedDocumentNumberCollection).DocumentNumber
);
Navigate(
 SecondScreen, 
 ScreenTransition.None
);
Set(
 varReset,
 false
);
Set(
 varReset,
 true
);

    Hi @mmbr1606 ,

    I looked at your suggestion but my GeneratedDocumentNumber.Text is always predefined:

    DJanssen_0-1706699472442.png

    This is because in the second screen in between the dashes the Document Number is built. The Default value of this field in the second screen is:

     

    Concatenate(CompanyNameText & "-" & TeamCodeDropdown.Selected.TeamCode & "-" & DisciplineCodeDropdown.Selected.DisciplineCode & "-" & DocumentTypeCodeDropdown.Selected.DocumentTypeCode, If(!IsBlank(AttachmentTypeCodeDropdown.Selected.DocumentAttachmentTypeCode), "-" & HasAttachmentDropdown.SelectedText.Value & "-" & AttachmentTypeCodeDropdown.Selected.DocumentAttachmentTypeCode & "-" & SequentialNumber2, "-" & SequentialNumberValue))

     

    DJanssen_1-1706699671052.png

    I'm aware that this is not the prettiest code, but I'm the only one building this Power App form and still pretty new to the Power Platform 😉

    Update: I have added code to make this field an empty string until the choices are filled in. Will try your solution now!

    If(IsBlank(TeamCodeDropdown.Selected.TeamCode) && IsBlank(DisciplineCodeDropdown.Selected.DisciplineCode) && IsBlank(DocumentTypeCodeDropdown.Selected.DocumentTypeCode), "", Concatenate(CompanyNameText & "-" & TeamCodeDropdown.Selected.TeamCode & "-" & DisciplineCodeDropdown.Selected.DisciplineCode & "-" & DocumentTypeCodeDropdown.Selected.DocumentTypeCode, If(!IsBlank(AttachmentTypeCodeDropdown.Selected.DocumentAttachmentTypeCode), "-" & HasAttachmentDropdown.SelectedText.Value & "-" & AttachmentTypeCodeDropdown.Selected.DocumentAttachmentTypeCode & "-" & SequentialNumber2, "-" & SequentialNumberValue)))

    Hi @WarrenBelz ,

    Could you maybe elaborate on your solution. I currently  have the following on my Reset field in my Power app:

    DJanssen_0-1706702112186.png

    So a the variable that you mentioned. 

     

    On my OnSelect button I have: 

    ClearCollect(
 GeneratedDocumentNumberCollection, // Create a collection to hold the generated document number
 {
 DocumentNumber: GeneratedDocumentNumber.Text
 }
);

Set(LastSubmittedCode, First(GeneratedDocumentNumberCollection).DocumentNumber);
If(!IsBlank(MainScreenTitleValue), Navigate(CreateDocumentNumber), Notify("Please fill in the Title field before proceeding", NotificationType.Error));
Set(varReset, false);

     

    Where do I set the varReset to true? I think on the second screen exactly on the moment where I set the LastSubmittedCode  and submit the data of the second screen to a list right?

    @DJanssen ,

    You need to set it to true directly after you set it to false - a Reset is triggered by changing a Variable from false to true. If you are confident it is false before you start the code, just set it to true.

    Also please tag who you want to respond - three way conversations confuse everyone.

    @WarrenBelz Ah I see. I tried your solution with the 2 condition resets when triggering the button. But this still did not work. Is there any other way? 
    Currently on my button Create a Document Number:

    ClearCollect(
 GeneratedDocumentNumberCollection, // Create a collection to hold the generated document number
 {
 DocumentNumber: GeneratedDocumentNumber.Text
 }
);

Set(LastSubmittedCode, First(GeneratedDocumentNumberCollection).DocumentNumber);
If(!IsBlank(MainScreenTitleValue), Navigate(CreateDocumentNumber), Notify("Please fill in the Title field before proceeding", NotificationType.Error));
Set(varReset, false);
Set(varReset, true);

    Hello a quick update. I managed to get it working by placing a TextLabel over the original input. I also reset the LastSubmittedCode to blank on the OnSave SharepointIntegration property. I think only the last thing could have solved the original problem anyways. Happy to have it working at least!
