Hi,
I have an asset library in SharePoint 2013 and want to update "Thumbnail Preview" (Internal Name - ThumbnailOnForm) Column of the library using Client Object Model. After researching , found that this column is of type - "Computed". My issue is , when I am updating using :-
oListItem["ThumbnailOnForm"] = "some string";..It throws an exception - "Invalid data has been used to updata the field".
Can anyone help me to guide how to update this column using COM ?
Any help will be highly appreciated !!!
