Property Value
A string representing the field name that uniquely identifies the column in a grid's column collection. By default, a null reference (Nothing in Visual Basic).
Thrown when a column's FieldName property is set after the column has been added to a grid's column collection.

When sorting and/or grouping data items, the name of the property in the data item and the value of the FieldName property must be identical otherwise neither sorting nor grouping will work.
