In my mind，sides checking the value is null or not，you should save the file posted onto the server and then show it。
The reason why your object is always null is that the file won't be submitted until you click a submit button or something like this……
Please debug your app and check whether your FileBytes is null or not。And check whether the colum！n.Name is fitable or not（my suggestionn is that you can use a fixed string instead of the column.Name instead）。
