Print data in Datagrid with AS3

Question

Dear all,
I would want to print out all the data inside my Datagrid which were populated in flash AS3. Taking into consideration that my datagrid has horizontalScrollPolicy and verticalScrollPolicy activated, how do I print the whole information?
This is the closest code I'm looking for, but I had alot of errors when I tried to use it, maybe because it is in AS2 & i convented it wrongly...
Link: http://www.knowledgesutra.com/forums/topic/29459-print-with-flash-and-datagrids-without-re sizing/
Do take a look at the code please.
My convented code from AS2 to AS3:
import fl.data.DataProvider;
import fl.controls.DataGrid;
import fl.controls.ScrollPolicy;
var dp:DataProvider = new DataProvider();
var fitPage:Boolean = false;
dp.addItem({no:"1", Winner_Name:"TestName1", Prize_Title:"TestPrizeTitleTestPrizeNameTestPrizeNameTestPrizeName", Prize_Name:"TestPrizeNameTestPrizeNameTestPrizeName"});
dp.addItem({no:"1", Winner_Name:"TestName1", Prize_Title:"TestPrizeTitle", Prize_Name:"TestPrizeName"});
dp.addItem({no:"1", Winner_Name:"TestName1", Prize_Title:"TestPrizeTitle", Prize_Name:"TestPrizeName"});
dp.addItem({no:"1", Winner_Name:"TestName1", Prize_Title:"TestPrizeTitle", Prize_Name:"TestPrizeName"});
dp.addItem({no:"1", Winner_Name:"TestName1", Prize_Title:"TestPrizeTitle", Prize_Name:"TestPrizeName"});

The error I get when I tried to print it:
TypeError: Error #1034: Type Coercion failed: cannot convert Object@26ec1d31 to flash.geom.Rectangle.

Answer 1

var columns:Array = ["Flash", "ActionScript", "Republic of Code"];
     trace(columns);
     //Start printing headers 
     var xPos:Number = 0;
     var tbWidth:Number = 0;
     //leave 2 rows margin at top
     var rowY:Number = _rowHeight * 2;
     for (var i = 0; i < columns.length; i++)
          //define xPos by adding the tbWidth of the last loop
          xPos = xPos + tbWidth;
          var column:DataGridColumn = targetDG.getColumnAt(i);
//get width of this column
          tbWidth = column.width;
          //add textField
          printClip.createTextField("header_" + i , printClip.getNextHighestDepth(), xPos, rowY,tbWidth, _rowHeight);
          var thisTb:TextField = printClip["header_" + i];
          //thisTb.setNewTextFormat(headerFormat);
          thisTb.defaultTextFormat = headerFormat;
          thisTb.border = true;
          thisTb.borderColor = 0xCCCCCC;
          thisTb.background = true;
          thisTb.backgroundColor = 0xD5EAFF;
          thisTb.text = column.headerText;
I got this AS2 code and I tried to convent it into AS3 but I have this error..
1046: Type was not found or was not a compile-time constant: DataGridColumn.
I have bold the line that causes this error. Anyone knows the solution for this error?
