Data Grid - Update Column with variable (not from data provider)


I have a data grid who’s data provider is set to an XML object.

            <mx:DataGrid id="streamMonitorGrid" dataProvider="{}" height="100%" width="100%">
                    <mx:DataGridColumn headerText="Title" dataField="@title"/>
                    <mx:DataGridColumn headerText="StationId" dataField="@stationId"/>
                    <mx:DataGridColumn headerText="Net Connection Status" id="nconnStatus" />

Title and StationId data is set to XML attributes from the XMLObject and display with no problem.

The issue that I have ran into is I want to set the 3rd column (marked as “Net Connection Status”) to a variable outside of the data provider XML object. The 3rd column should be set to any variable that I want - not within the XML object.

I cannot figure how to do the above, it almost seems like once a data provider is set you can’t set a column to anything but data within the data provider.

Any idea’s?
