RE: [flexcoders] How to dynamically populate the Header Text of Flex Datagrid from XML or from an arrayCollection

[Vaibhav Seth]

You need to make it hardcoded, as you hard code the dataField for every column.

Else you need to make use of regex and apply it to the XML to make out your 
nodes for the headers.

Good practice is not to pouplate it like this, instead make proper VOs and 
populate them with your data XML. Your work will be more structured and then 
you have control over the things you mentioned.

Subject: [flexcoders] How to dynamically populate the Header Text of Flex 
Datagrid from XML or from an arrayCollection


















 



  


    
      
      
      Hi,

I currently return an XML File(below) to Flex and have been assigning it to an 
array collection in order to populate a data grid.   As of now i have the 
header Text hardcoded . I want to put it dynamically from the arraycollection 
below, and some timee there are some of the columns need to hide and show 
too.How can i do this? 
 

var xLabels:Array = (Xs[0].label as Array);

labels = new ArrayCollection(xLabels); 

var hObj:Object=new Object();
for (var lObj:int=0; lObj < labels.length; lObj++)
{

hlabel =labels[lObj];
}


public var arrRawData:ArrayCollection = new ArrayCollection();      

__model.arrNewData = event.result.rawdata.record as ArrayCollection;
var xmlResult:XML = XML(event.result);

Any help would be greatly appreciated.

Thanks,
blue
