Hi All,
I am able to resolve the problem by using the type Object rather
than Array and now i use the following to get the data from the Object
instance..
[CODE]
if(obj!=null){
for (var key:String in obj) {
trace(" Key ="+key+" Value ="+obj[key]);
}
}
[/CODE]
How ever in my view i am generating the Columns of a DataGrid at
runtime and then assigning the dataProvider. Now the DataGrid is not
showing the values even though they are available in the Object i am
setting for the dataProvider..!!
Code to add the columns to the DataGird..
[CODE]
public function addColumns(propertyCollection:ArrayCollection):void{
for(var j:int=0;j<propertyCollection.length;j++){
var dgc:DataGridColumn = new
DataGridColumn("propertyHolderMap["+propertyNameTmp+"]");
trace("Column DataField ="+dgc.dataField);
dgc.headerText= propertyNameTmp;
gridCols.push(dgc);
}
myDataGrid.columns = gridCols;
}
....
<mx:DataGrid id="collectionBrowserItemView" width="100%" height="100%">
<mx:columns>
<mx:DataGridColumn headerText="Display Name " dataField="nodeLabel"
editable="false" >
<mx:itemRenderer>
<mx:Component>
<mx:HBox>
<mx:Image source="/apps/kwrite.png"
click="outerDocument.annotate(1)" width="15" height="15"/>
<mx:Label text="{data.nodeLabel}" />
</mx:HBox>
</mx:Component>
</mx:itemRenderer>
</mx:DataGridColumn>
</mx:columns>
</mx:DataGrid>
[/CODE]
My DataGird will always have a Column (which is column 0) and i add
columns depending on a User Action..
I Checked the keys passed from the Server and the datafield set to the
columns added at runtime and they match exactly..
Regards
Mars
