Use the dataField
property to specify the data field used to generate the summary,
the label
property to specify the name of the data field created to hold the summary data,
and the operation
property to specify how to create the summary for numeric fields.
You can specify one of the following values:
SUM
, MIN
, MAX
, AVG
, or COUNT
.
The following example creates summary rows based on two fields of the data provider of the AdvancedDataGrid control:
<mx:AdvancedDataGrid id="myADG" initialize="gc.refresh();"> <mx:dataProvider> <mx:GroupingCollection id="gc" source="{dpFlat}"> <mx:Grouping> <mx:GroupingField name="Region"> <mx:summaries> <mx:SummaryRow summaryPlacement="group"> <mx:fields> <mx:SummaryField dataField="Actual" label="Min Actual" operation="MIN"/> <mx:SummaryField dataField="Actual" label="Max Actual" operation="MAX"/> </mx:fields> </mx:SummaryRow> </mx:summaries> </mx:GroupingField> <mx:GroupingField name="Territory"> <mx:summaries> <mx:SummaryRow summaryPlacement="group"> <mx:fields> <mx:SummaryField dataField="Actual" label="Min Actual" operation="MIN"/> <mx:SummaryField dataField="Actual" label="Max Actual" operation="MAX"/> </mx:fields> </mx:SummaryRow> </mx:summaries> </mx:GroupingField> </mx:Grouping> </mx:GroupingCollection> </mx:dataProvider> <mx:columns> <mx:AdvancedDataGridColumn dataField="Region"/> <mx:AdvancedDataGridColumn dataField="Territory_Rep" headerText="Territory Rep"/> <mx:AdvancedDataGridColumn dataField="Actual"/> <mx:AdvancedDataGridColumn dataField="Estimate"/> <mx:AdvancedDataGridColumn dataField="Min Actual"/> <mx:AdvancedDataGridColumn dataField="Max Actual"/> </mx:columns> </mx:AdvancedDataGrid>

The property used inside the summary object, an instance of the SummaryObject class, to hold summary information.
For example, if you set the label
property to "Summary",
then the computed summary is placed in a property named "Summary"
in the summary object. The property of the SummaryObject instance
containing the summary data will appear as below:
{Summary:1000}

The function that should be performed on the children.
You can specify one of the following values for numeric fields:
SUM
, MIN
, MAX
, AVG
, or COUNT
.
기본값: SUM.
summaryFunction | 속성 |
public var summaryFunction:Function
언어 버전: | ActionScript 3.0 |
제품 버전: | Flex 3 |
런타임 버전: | Flash Player 9, AIR 1.1 |
Specifies a callback function to compute a custom data summary.
You use this property with the SummaryRow.summaryObjectFunction
property,
which defines an instance of the SummaryObject class used
to collect summary data for display in the AdvancedDataGrid control.
The function signature should be as follows:
function mySummaryFunction(iterator:IViewCursor, dataField:String, operation:String):Object
The built-in summary functions for SUM
, MIN
,
MAX
, AVG
, and COUNT
all return a Number containing
the summary data.
