Setting UserDisplayOptions

[ajcaterino]

We are currently using PnP Powershell to set UserDisplayOptions for a field:

Set-PnPField -List $ListName -Identity "Preparer" -Values @{ 'UserDisplayOptions' = 'NamePhoto' }

Is there a way to accomplish this in the PnP Core SDK? I can find the UserDisplayOptions property in /src/generated/SP/Internal/FieldUser.cs class and its corresponding interface, IFieldUser.cs, but I cannot find it in the SDK source code.

@ajcaterino : did you check if that property is the field SchemaXml properyt? If so, you can update the field SchemaXml and save it.

I'm not familiar with what you have suggested. Can you please provide some links for me to reference?

@ajcaterino : load the list field you want to update, read the SchemaXml property of that field (https://pnp.github.io/pnpcore/api/PnP.Core.Model.SharePoint.IField.html#PnP_Core_Model_SharePoint_IField_SchemaXml) and add/update the UserDisplayOptions="NamePhoto" element to the XML and then save it back (see https://pnp.github.io/pnpcore/using-the-sdk/fields-intro.html#updating-site-and-list-fields). The resulting field SchemaXml can look like this:

<Field ClientSideComponentId="00000000-0000-0000-0000-000000000000" DisplayName="PersonSingle" Format="Dropdown" List="UserInfo" Name="PersonSingle" 
Title="PersonSingle" Type="User" UserSelectionMode="1" UserSelectionScope="0" UserDisplayOptions="NamePhoto" ID="{5c2ce6f6-21f8-4399-b1a3-7c6142f720eb}" Version="2" StaticName="PersonSingle" SourceID="{7d644d41-d86e-4594-99de-479594a68fd9}" ColName="int1" RowOrdinal="0" />

Note that I did not try this yet myself, but it's a common approach to configure special field props.
