Setting a Managed Metadata field inside my code will show it as null inside PowerApp

I have a remote event reciever and inside it i am setting a managed metadata column named "DealStage", as follow:-



i["DealStage"] = "12e247f8-18ff-46be-95cd-fedc3adf1ddb"; //this represents a term label= New


now inside the list view i can see the managed metadata values as follow:-

but if i edit the list item the Deal Name will be null as follow:-

now if i modify the value using power app form, the Deal Stage will be shown correctly .. so not sure what is going on?

HI @johnjohn123 ,

Could you please share a bit more about your scenario?

How do you update the SP List "DealStage" column value?

Further, do you mean "DealStage" column value would be blank when you edit it using custom form app after you set a value for it using your code?


The custom form app (created using PowerApps) would pull record value from your SP List directly, no matter which way you use to update the SP List item value.

Please consider enable "Default SP List form" for your SP List rather than custom form from PowerApps, then edit your record again, check if the "DealStage" value has been populated with proper value.


Based on the code that you mentioned, I think there is something wrong with it. The "DealStage" Managed Metadata column contains the following properties:


  __metadata: {type: 'SP.Taxonomy.TaxonomyFieldValue'},
  Label: '<Your Label>',
  TermGuid: '<Term Guid>',
  WssId: -1


on your side, you need to provide values for all these child properties, then assign the whole child properties object to the "DealStage" column within your code.

Please check and see if the following article would help in your scenario:


e.g. You could consider modify your code formula as below (may be you need to convert the following formula into your C# code):

i["DealStage"].TermGuid = "12e247f8-18ff-46be-95cd-fedc3adf1ddb";
i["DealStage"].__metadata= "SP.Taxonomy.TaxonomyFieldValue";
i["DealStage"].Label="<Your Label>";
i["DealStage"].WssId = -1;
