| "description": "The SummaryField2 class represents a single property in a SummaryRow instance. Each SummaryRow instance specifies one or more SummayField2 instances that are used to create a data summary. <p><b>Note: </b>In the previous release of Flex, you used the SummaryField class to create summary data. The SummaryField2 class is new for Flex 4 and provides better performance than SummaryField.</p> <p>Use the <code>dataField</code> property to specify the data field used to generate the summary, the <code>label</code> property to specify the name of the data field created to hold the summary data, and the <code>summaryOperation</code> property to specify how to create the summary for numeric fields. You can specify one of the following values: <code>SUM</code>, <code>MIN</code>, <code>MAX</code>, <code>AVG</code>, or <code>COUNT</code>.</p> Or you can specify an ISummaryCalculator implementation to calculate the summaries. <p>The following example creates summary rows based on two fields of the data provider of the AdvancedDataGrid control:</p> <pre>\\n <mx:AdvancedDataGrid id="myADG"\\n initialize="gc.refresh();">\\n <mx:dataProvider>\\n <mx:GroupingCollection id="gc" source="{dpFlat}">\\n <mx:Grouping>\\n <mx:GroupingField name="Region">\\n <mx:summaries>\\n <mx:SummaryRow summaryPlacement="group">\\n <mx:fields>\\n <mx:SummaryField2 dataField="Actual"\\n label="Min Actual" summaryOperation="MIN"/>\\n <mx:SummaryField2 dataField="Actual"\\n label="Max Actual" summaryOperation="MAX"/>\\n </mx:fields>\\n </mx:SummaryRow>\\n </mx:summaries>\\n </mx:GroupingField>\\n <mx:GroupingField name="Territory">\\n <mx:summaries>\\n <mx:SummaryRow summaryPlacement="group">\\n <mx:fields>\\n <mx:SummaryField2 dataField="Actual"\\n label="Min Actual" summaryOperation="MIN"/>\\n <mx:SummaryField2 dataField="Actual"\\n label="Max Actual" summaryOperation="MAX"/>\\n </mx:fields>\\n </mx:SummaryRow>\\n </mx:summaries>\\n </mx:GroupingField>\\n </mx:Grouping>\\n </mx:GroupingCollection>\\n </mx:dataProvider>\\n \\n <mx:columns>\\n <mx:AdvancedDataGridColumn dataField="Region"/>\\n <mx:AdvancedDataGridColumn dataField="Territory_Rep"\\n headerText="Territory Rep"/>\\n <mx:AdvancedDataGridColumn dataField="Actual"/>\\n <mx:AdvancedDataGridColumn dataField="Estimate"/>\\n <mx:AdvancedDataGridColumn dataField="Min Actual"/>\\n <mx:AdvancedDataGridColumn dataField="Max Actual"/>\\n </mx:columns>\\n </mx:AdvancedDataGrid>\\n </pre> The <code><mx.SummaryField2></code> inherits all the tag attributes of its superclass, and defines the following tag attributes:</p> <pre>\\n <mx:SummaryField2\\n <b>Properties </b>\\n dataField="<i>No default</i>"\\n label="<i>No default</i>"\\n summaryOperation="<i>SUM</i>"\\n />\\n </pre>", | |
