I have an entity, entityX and it has an option set with 3 possible values (Interior, Exterior, or Both).

The default option set value is set to Unassigned Value on the Internal/External Field shown circled in black on the leftmost part of the image below.

Under certain circumstances, I need to be able to set this field selected value back to Unassigned Value so neither of the 3 options are selected and the field looks exactly as it does below on the leftmost part of the image.

What is the JavaScript command I can use to do this?

The following command doesn't work Xrm.Page.data.entity.attributes.get(typeMultiOption).setValue(null);

Does anyone know or can anyone advise me as to what command will set this back to Unassigned Value so it looks like it does in the image below circled in black on the left?

RE: V9 Dynamics 365 JavaScript to re-select "Unassigned Value" as currently set optionset value on form?

I was able to solve this problem using the following V9 JavaScript Code:

var formContext = executionContext.getFormContext(); formContext.data.entity.attributes.get(typeMultiOption).setValue(null); formContext.getAttribute(nameField).setValue(null); formContext.data.refresh();

Problem solved!
