Get a field's value at the specified row in a format suitable for display.
Parameters
- field: SF

The value of the field at the specified row.

Remarks
The core of the client does not need to know the type of the return value. getViewValue() is called by the Cell Painter associated with the cell/subgrid. The cell painter expects a certain type of view value and casts the result accordingly.
