Extending DataGrid and more conveniant way to style a row

The listItems tends to be the most useful way for styling things. and instead of iterating through all items for each row, I instantiate MessagesDataGridRow in getRowAt():

package com.sandman.view
{
 import mx.controls.DataGrid;
 
 public class MessagesDataGrid extends DataGrid
 {
  public function MessagesDataGrid() {
   super();
  }
  
  public function getRowAt(rowIndex:int):MessagesDataGridRow {
   
   var row:* = super.listItems[rowIndex];
   return new MessagesDataGridRow(row);
  }

 }
}

MessagesDataGridRow:

package com.sandman.view
{
 public class MessagesDataGridRow
 {
  private var row:*;
  public function MessagesDataGridRow(itemRow:*) {
   row = itemRow;
  }
  
  public function setStyle(attribute:String, value:String):void {
   var length:int = row.length;
   var i:int;
   for (i=0; i<length; i++) {
    row[i].setStyle(attribute, value);
   }
  }

 }
}

Example usage:

var row:MessagesDataGridRow = yourGrid.getRowAt(3);
row.setStyle('fontWeight', 'bold');
row.setStyle('fontStyle', 'italic');

You'll likely want to modify this to suit your needs.
