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

[Digitalosophy]

Hello,

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


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




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?

TIA

It is accurate to say that datagrid is developed with the idea that it will be driven by data.

Although there are options, I would not be keen use them.

Still, if you want to go outside of your dataprovider, you can, for example, use an itemrenderer, and override set data; you can then pull in whatever data you need at that point. You could also extend datagridcolumn, and maybe a couple of other things.
