I believe that this was suggested to me by Alex. I think your way should work too though.

hi Joan,

Just wondering is there any particular reason that you don't change the background color in the data() setter like this:

public function set data(value:Object ):void{
     
    if( value.myColumnName > 50){
    //change bg to red
  }else{
    //change to other color
  }

}

The "color" style of Text only affects the text and the not the background. Text doesn't actually have a background color so you must create an itemRenderer with a backgroundColor and then set it. This example was posted on another flexcoders thread entitled "datagrid". This itemRenderer will turn the background of a row to red if the value of the column  "myColumnName" in that row is over 50.

 

package {

 

    import mx.controls.Label;

    import mx.controls.dataGridClasses.*;

    import mx.controls.DataGrid;

    import flash.display.Graphics;

    import mx.styles.StyleManager;

 

    [Style(name="backgroundColor", type="uint", format="Color", inherit="no")]

   

      public class BackgroundComp extends Label {

 

       override protected function updateDisplayList(unscaledWidth:Number,

                                                                                unscaledHeight:Number):void

       {

                  super.updateDisplayList(unscaledWidth, unscaledHeight);

                 

                  var g:Graphics = graphics;

                  g.clear();

                  var grid1:DataGrid = DataGrid(DataGridListData(listData).owner);

                  if (grid1.isItemSelected(data) || grid1.isItemHighlighted(data))

                        return;

                  if (data.myColumnName > 50)

                  {

                        g.beginFill(0xFF0000);

                        g.drawRect(0, 0, unscaledWidth, unscaledHeight);

                        g.endFill();

                }

      }

  }

 

}

I'm using an itemRenderer to set the text color via the setStyle
("color",<color>) construct, but it doesn't appear to be that simple
for backgroundColor. Is the data() method part of the renderer API?
