hi,

i am in a deadlock with some actionscript problem..

suppose i have an xmlCollecition list:
var xmlList:XMLList = new XMLList(master_collList.getItemAt(0).objective_function.constraints.constraint);
      for each(var xmlVal:XML in xmlList)
      dataStore.push(xmlVal.toString());
            conDG.dataProvider = dataStore;

so,  i am providing the dataProvider of the conDG(an instance of my datagrid) with an array containing xml to strings..

now,  in my datagrid, i want to add append another string to the dataProvider of conDG..

how do i do this ?

basically i have an application where users can edit the values already in the dataprovider via the datagrid..but when the user clicks the add button and edits the grid, the changes are not effected becuz the dataProvider does not contain xml but strings...

any help?

 this is code for my user input.. :

<?xml version="1.0" encoding="utf-8"?>
<s:Group xmlns:fx="http://ns.adobe.com/mxml/2009"
             xmlns:s="library://ns.adobe.com/flex/spark"
             xmlns:mx="library://ns.adobe.com/flex/mx"
             top="20"
             left="20">

      
      <fx:Declarations>
            <!-- Place non-visual elements (e.g., services, value objects) here -->
      </fx:Declarations>
      <fx:Script source="ConstraintScript.as"/>
      <fx:Metadata>
            [ResourceBundle("optimizationUI")]
      </fx:Metadata>
      
      <s:Button id="addBT" x="178" y="1" skinClass="skins.AddBTskin"
                     click="addBT_clickHandler(event)"/>
      <s:Button id="deleteBT" x="256" y="1" skinClass="skins.DelBTskin"
                     click="deleteBT_clickHandler(event)"/>
      
      <mx:DataGrid width="600" height="220" id="conDG" x="2" y="30">
            <mx:columns>
                  <mx:DataGridColumn headerText="{resourceManager.getString('optimizationUI','constraint')}"/>
            </mx:columns>
      </mx:DataGrid>
      
</s:Group>

>> in my datagrid, i want to add append another string to the dataProvider of conDG..

1. push another string into 'dataStore'

2. Assign it again: conDG.dataProvider = dataStore;

3. and call
    conDG.dataProvider.refresh();

(You could try to ommit step 2)
