如何将所有拖动的物品放到第二格（dg2）？

解决方案

如果您正在寻找从访问放入 dg2 dg1 ，这里是怎么做的：

  var list：ListCollectionView = dg2.dataProvider; 
 for（i = 0; i< list.length; i ++）
 trace（list.getItemAt（i））; 
  

顺便提一句，这是错误的：

  change =selectedItem =（event.target as DataGrid）.selectedItem.contactName; 
 selectedSno =（event.target as DataGrid）.selectedItem.contactNo; 
  

你想用它完成什么？

<mx:DataGrid id="dg1" dataProvider="{cNumbersList}" cornerRadius="3" 
    allowMultipleSelection="true" 
    change="selectedItem=(event.target as DataGrid).selectedItem.contactName;
            selectedSno=(event.target as DataGrid).selectedItem.contactNo;"
    dropEnabled="true" dragMoveEnabled="true" dragEnabled="true" 
    fontWeight="normal">
        <mx:columns>
            <mx:DataGridColumn dataField="contactName" headerText="Name"/>
            <mx:DataGridColumn dataField="contactNo" 
                headerText="ContactNo"/>                
        </mx:columns>
</mx:DataGrid>

<mx:DataGrid id="dg2" cornerRadius="3" allowMultipleSelection="true" 
    visible="false" dataProvider="{}" dropEnabled="true" 
    dragMoveEnabled="true" dragEnabled="true" fontWeight="normal">

    <mx:columns>
        <mx:DataGridColumn dataField="contactName" headerText="Name"/>
        <mx:DataGridColumn dataField="contactNo"
            headerText="ContactNo"/>                
    </mx:columns>
</mx:DataGrid>

How can I get all dragged items in to second grid(dg2)?

解决方案

If you are looking to access the items dropped into dg2 from dg1, here is how to do that:

var list:ListCollectionView = dg2.dataProvider;
for(i = 0; i < list.length; i++)
  trace(list.getItemAt(i));

Btw, something tells me that this is wrong:

change="selectedItem=(event.target as DataGrid).selectedItem.contactName;
selectedSno=(event.target as DataGrid).selectedItem.contactNo;"
