Read only grid without paging

Computed columns whose value depends on several fields may be defined by adding a column with no asp-for, ie not connected to any property, but with just a name.

Computed columns MUST have a custom display template that defines the way they combine the data item properties. Clearly they can't have an edit template, so they are defined readonly. This way, the display template is used also if the row is rendered in edit mode. Since the column is not specific to any property the custom template receives the full item model in Html.Item<T>().In the example below we removed the price and currency columns, to add a computed column that combine them.
