Does creating the columns array first and then setting them all at once help?

  var columns:Array = [];
  // build array
  dgmisure.columns = columns;

Under FlashPlayer 8 it's the same . ;-)
I don't need sortable, resize but i'm using a dataGrid because:

1) For a column i have a dataBinding ( java Vector)
2) For row of datagrid i have anohter dataBinding (ActionScript java Class)

With the i have no idea if this is possibile.

I have found the dynamically building DataGrid columns is very slow as well.

If you do not need sortable, resizable columns, you might try a custom cell 
renderer in a List, instead of a DataGrid.

You might want to test this under the new FlashPlayer 8 beta.

Hi, if you can see my code, work fine ok, but when flex go to "render" the
performance it's very very slow.


1) Before this function i call a AMF response it's very fast
2) Some other flex component are rendered very fast.

About you, this is a bad approach? can you give some better solution
Thank's
