Prohibit users from entering records into SharePoint List

(0) ShareShare
ReportReport
Posted on by Community Power Pla... Microsoft Employee

I am creating a survey in PowerApps and I would like to make sure that each user can only submit one list item into the SharePoint List.

 

I created a collection called Submitters which contains a distinct list using the Created by field.

 

I would like to make sure that the button that takes them to the survey is disabled. Any suggestions?

    Hi @Anonymous,

     

    Do you want one user can only submit one item and if one is already submit the Button will disable?

    I think you can try as the following workaround:

     

    App Test:

    Add one button in the App and rename Button_Submitters, and

    Button_Submitters.OnSelect: ClearCollect(Submitters,Distinct('20190201survey',Author.DisplayName))

    Button_Submitters.Visible: If(User().FullName in Submitters.Result,false,true) 

    Add one Label1 and its Text:User().Full Name to test the Button.

    Result Test:

    1. 20190204only one record.gif

         2.20190204 only one record3.jpg

     

     

    Hope this can be helpful.

    Best Regards.
