Flex, Putting SQLite result into a ItemRenderer

Using the following SQLite statement:

SELECT Customer, SUM(OrderAmount) AS TotalOrder FROM OrdersTable GROUP BY Customer

I get the result of total sum (total order) of each customer

How can I put the above result into a itemRenderer label.text ?

<s:ItemRenderer>
   <s:Label id="customerName" text=??? />
   <s:Label id="totalOrder" text=??? />
</s:ItemRenderer>

thanks

ItemRenderer's have a data property which the Flex List control sets on each renderer. You can bind the text property of a Label to the data, override the setter for the data property, or add an event listener for the "dataChange" event.

When binding you can use curly brace expressions like this:

<s:Label text="{data.customerName}" />

This assumes that the data provider for your List is populated w/an object that has the property customerName ;)

The other two approaches require that you write some code that sets the label's text property.

You can find many examples of using a Flex ItemRenderer, such as these:

Whenever we set data to a dataprovider it automatically set to its item renderer, if you are using custom itemrendere then do this...

[Bindable] private var _customerName:String;
[Bindable] private var _totalOrder:String;

override public function set data(value:Object):void{
  this.data = value;
  _customerName = value. property   //propertyName containing customer name
  _totalOrder = value. property   //propertyName containing totalOrder
}

   <s:Label id="customerName" text="{_customerName}" /> 
   <s:Label id="totalOrder" text="{_totalOrder}" />

or

<s:ItemRenderer>    
   <s:Label id="customerName" text="{data.properyNamecontainCustomerName}" />    
   <s:Label id="totalOrder" text="={data.properyNamecontaintotalOrder} " />    
</s:ItemRenderer>
