Allow empty selection in combobox with SB List Person field

(0) ShareShare
ReportReport
Posted on by RobChilds 94

I have built a simple asset management SharePoint List with a PowerApps front end.

 

In PowerApps I have a combobox (in a form) that links to a person field in a SharePoint list.

 

I can add people into this combobox box no problem, but it seems I'm unable to change it back to a blank box.  (I can only change it to another active user).

 

Thanks,

Rob

    @RobChilds Are you not able to cancel the selected option after you click on the dropdown?

    @BhargavPatel - I can click the x in the ComboBox (in the form/datacard),  but it doesn't submit it to the SharePoint List.

     

    Thanks

    @RobChilds Are you using the SubmitForm( ) or Patch( ) function to create/update the record?

    @BhargavPatel - SubmitForm()

    @RobChilds I was able to remove the selected person using SubmitForm( ) function.

    Is your people field single or multi selection?

    Please also try removing the DataCard and then add it back to the form, save, and publish the app.

    @RobChilds ,

    If you have not turned on your Formula Level Error Management, try doing this

    Other than that, assuming you have not changed the Items or DefaultSelectedItems from what Power Apps set initially, it should work.

    Thanks @BhargavPatel @WarrenBelz 

     

    I think I must've changed the datacard in some way as removing it and re-adding (and then saving) it seems to now be working.

     

    I couldn't see what I had changed but clearly I must have!

     

    Thanks kindly,

    Rob
