Gets or sets the name of the field or property in the data associated with the column.

Gets the item renderer for the item that is being edited or the header renderer that is being clicked or resized.

Gets the reason the itemEditEnd event was dispatched. This property is only valid for events of type DataGridEvent.ITEM_EDIT_END.

The possible values are defined in the DataGridEventReason class.
