Hi @CharlesMacleod , Thanks very much for your reply. Our requirement is to check "Show domain and subtypes descriptions" off by default, when attribute table pane is opened from a particular feature layer.
I did some research and found that this setting is available in TablePaneViewModel > ViewState property > DisplaySubtypeDomainDescriptions, but I am not sure how to access TablePaneViewModel. Could you please advise? Thanks.
