Hey Flexers
I created a datagrid to represent a shopping cart. Now, I'm having a
problem updating the total when the quantity is changed. Right now it
just gives the total because I have the quantity set to 1, but if the
users types in a different quantity I want it to update the total. If
anybody has any suggestions, I'd appreciate it. Below is my calculate
function and my datagrid.
Thanks
Sal
public function calculateTotal():void{
var t:Number = 0;
var n:Number = 0;
for(var i:int = 0; i < myDP.length; i++){
n += myDP[i].qty;
t += myDP[i].price * myDP[i].qty;
}
total = t;
numProducts = n;
}
<mx:DataGrid width="100%" height="250" dataProvider="{myDP}"
textAlign="center" id="cartGrid">
<mx:columns>
<mx:DataGridColumn
id="qty" headerText="Qty"
rendererIsEditor="true" dataField="qty"
itemRenderer="mx.controls.TextInput" editorDataField="value" width="24"/>
<mx:DataGridColumn
headerText="Price" width="35"
dataField="price" labelFunction="myLabelFunction"/>
</mx:columns>
</mx:DataGrid>
