To specify the grouping fields of your flat data, you pass a Grouping instance to the <code>GroupingCollection.grouping</code> property. The Grouping instance contains an Array of GroupingField instances, one per grouping field. </p> <p>The following example uses the Grouping class to define two grouping fields: Region and Territory.</p> <pre>\\n <mx:AdvancedDataGrid id="myADG"\\n <mx:dataProvider>\\n <mx:GroupingCollection id="gc" source="{dpFlat}">\\n <mx:grouping>\\n <mx:Grouping>\\n <mx:GroupingField name="Region"/>\\n <mx:GroupingField name="Territory"/>\\n </mx:Grouping>\\n </mx:grouping>\\n </mx:GroupingCollection>\\n </mx:dataProvider>\\n \\n <mx:columns>\\n <mx:AdvancedDataGridColumn dataField="Region"/>\\n <mx:AdvancedDataGridColumn dataField="Territory"/>\\n <mx:AdvancedDataGridColumn dataField="Territory_Rep"/>\\n <mx:AdvancedDataGridColumn dataField="Actual"/>\\n <mx:AdvancedDataGridColumn dataField="Estimate"/>\\n </mx:columns>\\n </mx:AdvancedDataGrid>\\n </pre> The <code><mx.GroupingField></code> inherits all the tag attributes of its superclass, and defines the following tag attributes:</p> <pre>\\n <mx:GroupingField\\n <b>Properties </b>\\n caseInsensitive="false|true"\\n compareFunction="<i>No default</i>"\\n descending="false|true"\\n groupingFunction="<i>No default</i>"\\n groupingObjectFunction="<i>No default</i>"\\n name="null"\\n numeric="false|true"\\n summaries="<i>No default</i>"\\n />\\n </pre>", | |
