Your code looks OK to me. So I’d
try to debug it further by putting maybe putting an alert on the change event
of the datagrid that prints the selectedItem.price and just make sure that all
is kosher. And you can of course move on from there with the various debugging
tips we have in the docs J

Subject: [flexcoders] Extracting
Data from a DataGrid
Ok, heres the issue:
I have a data grid which is populated from a
result of a
remoteObject call, the result is an Array of Value
Objects:
<mx:DataGrid id="myDataGrid"
dataProvider="{srv.getRates.result}">
<mx:columns>
<mx:Array>
<mx:DataGridColumn columnName="supplier" headerText="Company
Name" width="125"/>
<mx:DataGridColumn
columnName="price" headerText="Price"
labelFunction="formatCurrency"
width="75"/>
</mx:Array>
</mx:columns>
</mx:DataGrid>
Now I want to add a ControlBar at the bottom of
the dataGrid which
shows the price when the user selects a row (by
clicking on it), so
I created a custom component controlBar and added
this line below
the code above:
<comp:taxiControllbar
dataObject="(myDataGrid.selectedItem}"/>
and the code for the component is:
<?xml version="1.0"
encoding="utf-8"?>
<mx:ControlBar xmlns:mx="http://www.macromedia.com/2003/mxml">
<mx:Script>
var dataObject:Object;
</mx:Script>
<mx:Text
text="{dataObject.price}"/>
</mx:ControlBar>
Well, it doesn't work when I select the row, and
your job is to tell
me how thick I am and say, don't be daft, this is
how you do it!
Cheers,
Iain
