[flexcoders] Re: Creating a DataProvider by dynamic loading

[bhaq1972]

If you want to add columns dynamically, you need something like this

var colNum:int=5
for(var i:int=0;i<colNum;i++)
{
  var col:DataGridColumn = new DataGridColumn();
  col.dataField = "some value1";
  col.headerText = "some value2";
  
  myDataGrid.columns.push(col);
}
you'd then generate your dataProvider (could be an ArrayCollection, 
Array, XML, whatever)
myDataGrid.dataProvider = myDataProvider;

hope this helps
