NewFixedState Returns the new fixed state of the row. If this property returns true then the user is attempting to fix the row. If it returns false then the user is attempting to unfix the row. To cancel the operation of fixing or unfixing the row set the Cancel property of the event args to true.
Row Returns the row the user is attempting to fix or unfix. The origianl fixed state of the row can be obtained using the UltraGridRow.Fixed property or querying the RowsCollection.FixedRows collection. The new state is provided by the NewFixedState property of this event args. To cancel the operation of fixing or unfixing the row set the Cancel property of the event args to true.
