Type of Descriptor	FieldType	FieldValue type
References a single DomInstance value	Guid	Guid

Defines a DOM field that references a DomInstance by storing the ID of that instance in the form of a Guid. Compared to the DomInstanceFieldDescriptor, this descriptor also references a specific value of that DomInstance. The configuration is the same as that of the DomInstanceFieldDescriptor, but it adds the FieldDescriptorId property that references a specific FieldValue. This way, the DOM low-code app form will show the specified value of the DomInstance alongside the name in the dropdown.

Defining the FieldDescriptor

var descriptor = new DomInstanceValueFieldDescriptor("my_referenced_module", fieldDescriptorId)
{
    ID = new FieldDescriptorID(Guid.NewGuid()),
    Name = "My DOM value reference field",
    FieldType = typeof(Guid),
    DomDefinitionIds = { domDefinitionId } // Optional
};

Adding a value for the FieldDescriptor

var instance = new DomInstance 
{        
    ID = new DomInstanceId(Guid.NewGuid()),
    DomDefinitionId = domDefinitionId
};

var instanceId = Guid.Parse("8000971e-982a-2151-10a2-1803aa100359");
instance.AddOrUpdateFieldValue(sectionDefinitionId, fieldDescriptorId, instanceId);
