The GroupingCollection class lets you create grouped data from flat data for display in the AdvancedDataGrid control. When you create the instance of the GroupingCollection from your flat data, you specify the field or fields of the data used to create the hierarchy.

To populate the AdvancedDataGrid control with grouped data, you create an instance of the GroupingCollection class from your flat data, and then pass that GroupingCollection instance to the data provider of the AdvancedDataGrid control. To specify the grouping fields of your flat data, you pass a Grouping instance to the GroupingCollection.grouping property. The Grouping instance contains an Array of GroupingField instances, one per grouping field.

The following example uses the GroupingCollection class to define two grouping fields: Region and Territory.

  <mx:AdvancedDataGrid id="myADG"    
    <mx:dataProvider> 
      <mx:GroupingCollection id="gc" source="{dpFlat}"> 
        <mx:grouping> 
          <mx:Grouping> 
            <mx:GroupingField name="Region"/> 
            <mx:GroupingField name="Territory"/> 
          </mx:Grouping> 
        </mx:grouping> 
      </mx:GroupingCollection> 
    </mx:dataProvider>  
     
    <mx:columns> 
      <mx:AdvancedDataGridColumn dataField="Region"/> 
      <mx:AdvancedDataGridColumn dataField="Territory"/> 
      <mx:AdvancedDataGridColumn dataField="Territory_Rep"/> 
      <mx:AdvancedDataGridColumn dataField="Actual"/> 
      <mx:AdvancedDataGridColumn dataField="Estimate"/> 
    </mx:columns> 
  </mx:AdvancedDataGrid>

MXML 구문

MXML 구문 숨기기

The <mx.GroupingCollection> inherits all the tag attributes of its superclass, and defines the following tag attributes:

  <mx:GroupingCollection
  Properties 
    grouping="No default"
    source="No default"
    summaries="No default"
  />

This Class has been deprecated and replaced by a new Class GroupingCollection2 which provide faster, improved performance and a new summary calculation mechanism. Class SummaryField has also been deprecated and replaced by a new Class SummaryField2. Properties operation and summaryFunction are not present in the Class SummaryField2. A new property summaryOperation is introduced in SummaryField2.

grouping

속성

grouping:Grouping

언어 버전:

ActionScript 3.0

제품 버전:

Flex 3

런타임 버전:

Flash Player 9, AIR 1.1

Specifies the Grouping instance applied to the source data. Setting the grouping property does not automatically refresh the view, so you must call the refresh() method after setting this property.

구현
public function get grouping():Grouping
public function set grouping(value:Grouping):void

source

속성

source:Object[재정의]

언어 버전:

ActionScript 3.0

제품 버전:

Flex 3

런타임 버전:

Flash Player 9, AIR 1.1

The source collection containing the flat data to be grouped. If the source is not a collection, it will be auto-wrapped into a collection.

구현
override public function get source():Object
override public function set source(value:Object):void

메서드

public function cancelRefresh():void

언어 버전:

ActionScript 3.0

제품 버전:

Flex 3

런타임 버전:

Flash Player 9, AIR 1.1

If the refresh is performed asynchronously, cancels the refresh operation and stops the building of the groups. This method only cancels the refresh if it is initiated by a call to the refresh() method with an argument of true, corresponding to an asynchronous refresh.

getParent

()

메서드

protected function getParent(node:Object):*

언어 버전:

ActionScript 3.0

제품 버전:

Flex 3

런타임 버전:

Flash Player 9, AIR 1.1

Returns the parent of a node. The parent of a top-level node is null.

매개 변수

node:Object — The Object that defines the node.

반환값

* — The parent node containing the node as child, null for a top-level node, and undefined if the parent cannot be determined.

getRoot

()

메서드

override public function getRoot():Object

언어 버전:

ActionScript 3.0

Return super.source, if the grouping property is set, and an ICollectionView instance that refers to super.source if not.

반환값

Object — The object to return.

refresh

()

메서드

public function refresh(async:Boolean = false):Boolean

언어 버전:

ActionScript 3.0

제품 버전:

Flex 3

런타임 버전:

Flash Player 9, AIR 1.1

Applies the grouping to the view. The IGroupingCollection does not detect changes to a group automatically, so you must call the refresh() method to update the view after setting the group property.

The refresh() method can be applied asynchronously by calling refresh(true).

When refresh() is called synchronously, a client should wait for a CollectionEvent event with the value of the kind property set to CollectionEventKind.REFRESH to ensure that the refresh() method completed.

매개 변수

async:Boolean (default = false) — If true, defines the refresh to be asynchronous. By default it is false denoting synchronous refresh.

반환값

Boolean — true if the refresh() method completed, and false if the refresh is incomplete, which can mean that items are still pending.
