column | property |

`public var column:AdvancedDataGridColumn`

Language Version : | ActionScript 3.0

Product Version : | Flex 3

Runtime Versions : | Flash Player 9, AIR 1.1

A reference to the AdvancedDataGridColumn instance corresponding to this AdvancedDataGridHeaderInfo instance.

columnSpan | property |

`public var columnSpan:int`

Language Version : | ActionScript 3.0

Product Version : | Flex 3

Runtime Versions : | Flash Player 9, AIR 1.1

Number of actual columns spanned by the column header when using column groups.

depth | property |

`public var depth:int`

Language Version : | ActionScript 3.0

Product Version : | Flex 3

Runtime Versions : | Flash Player 9, AIR 1.1

The depth of this AdvancedDataGridHeaderInfo instance in the columns hierarchy of the AdvancedDataGrid control, if this column is part of a column group.

headerItem | property |

`public var headerItem:IListItemRenderer`

Language Version : | ActionScript 3.0

Product Version : | Flex 3

Runtime Versions : | Flash Player 9, AIR 1.1

A reference to IListItemRenderer instance used to render the column header.

index | property |

`public var index:int`

Language Version : | ActionScript 3.0

Product Version : | Flex 3

Runtime Versions : | Flash Player 9, AIR 1.1

The index of this AdvancedDataGridHeaderInfo instance in the AdvancedDataGrid control.

internalLabelFunction | property |

`public var internalLabelFunction:Function`

Language Version : | ActionScript 3.0

Product Version : | Flex 3

Runtime Versions : | Flash Player 9, AIR 1.1

A function that gets created if the column grouping requires extracting data from nested objects.

For example, if each data row appears as:

    row = {.., .., Q1: { y2005: 241, y2006:353}};

and you define a column group as:

         <mx:AdvancedDataGridColumnGroup dataField="Q1">
            <mx:AdvancedDataGridColumn dataField="y2005">
            <mx:AdvancedDataGridColumn dataField="y2006">
         </mx:AdvancedDataGridColumnGroup>

The function for the column corresponding to y2005 is defined as:

         function foo():String
         {
            return row["Q1"]["2005"];
         }

The function also handles the case when any of the column or column groups uses a label function instead of a data field.
