I have a Power Apps form (customized SharePoint form), where I have a requirement to display a multi-select dropdown (Region) as checkboxes. The data submits correctly, and when a submitted item is reopened, the checkboxes still retain their values. BUT, if a submitted item is edited (re-submitted), the column value disappears, and the checkboxes clear out. Here's how I have it set up:

  • Multi-select Choice field (Region). Added 5 checkboxes to the data card.

  • Checkbox properties:

    OnCheck & Uncheck: 
                  If(Checkbox2.Value, "UO"),
                  If(Checkbox2_1.Value, "USH"),
                  If(Checkbox2_2.Value, "USJ"),
                  If(Checkbox2_3.Value, "USS"),
                  If(Checkbox2_4.Value, "Other"));
             ClearCollect(Region5,Filter(Region5, !IsBlank(Value)))
     Default: Self.Text in Concat(ThisItem.Region, Value&",")
  • DatacardValue Properties: Defaultselecteditems: Region5

  • Datacard Properties: Default: Thisitem.Region Update: Region5

Region 5 is the name of my collection for the "Region" Choice (checkbox) field.

Again, this set of properties successfully logs the selected checkbox(es) into the SharePoint list. But when a user opens an existing item, modifies it, then clicks the 'Submit' button again (OnSelect - SubmitForm(SharePointForm1), that value clear out in SharePoint and the form.

Any help would be great. This is driving me crazy.


  • You will have to populate the Region5 collection when opening list form in edit mode. Example: try setting SharePointIntegration.OnEdit to ClearCollect(Region5, ThisItem.Region). Let me know if it works for you. Mar 21 at 14:06
  • I just added that code you suggested to OnEdit property for SharePointIntegration and got an error: "The function ClearCollect has some invalid arguments". And "Name isn't valid. 'ThisItem' isn't recognized.

    Try: ClearCollect(Region5, SharePointIntegration.Selected.Region);. Mar 21 at 14:14
  • That did it. THANK YOU. I ended up using this in my OnEdit -EditForm(SharePointForm1); ClearCollect(Region5, SharePointIntegration.Selected.Region). Works perfectly

  • Yes, EditForm(SharePointForm1); is already there by default. Glad it worked for you. I have added same as an answer below. Mar 21 at 14:53

I think you will have to populate the Region5 collection again when opening the SharePoint list form in edit mode.

Try using below formula in SharePointIntegration.OnEdit property:

ClearCollect(Region5, SharePointIntegration.Selected.Region);

Where SharePointForm1 is the name of form control and Region is the name of your choice column in the list.
