How to use External method from a Datagrid ItemRender

Posted by Flex Xpert at 11:42 PM

Hi Guys , I recentally found a cool trick. the trick is How you will call external method from datagrid itemrender that do some action on your current datagrid.


I am posting a simple Example that is the Answer of this Question. By using this Code your can perform any action on datagrid from that own datagrid ItemRenderButton or Image.

Code is as Follows

     mx:Script
import mx.collections.ArrayCollection;
         import mx.controls.Alert;
            [Bindable]private var myDP:ArrayCollection = new ArrayCollection([
               {label1:"Order #2314", quant:3, Sent:true},
               {label1:"Order #2315", quant:3, Sent:false} ]);               
            public function showRowID():void{
             Alert.show("My selected row is"+myDG.selectedIndex.toString());
            }
        
    mx:Script

    mx:DataGrid id="myDG" dataProvider="{myDP}" variableRowHeight="true"
       mx:columns
          mx:DataGridColumn dataField="label1" headerText="Order #"
          mx:DataGridColumn dataField="quant" headerText="Qty"
            mx:itemRenderer
              mx:Component
mx:Button label="{'Click me'+data.quant}" click="{outerDocument.showRowID();}"
      mx:Component
            mx:itemRenderer
            mx:DataGridColumn
       mx:columns 
    mx:DataGrid
