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.

About you, this is a bad approach? can you give some better solution Thank's devis function Init_Taglie() { dgmisure.removeAllColumns(); myColumn= new DataGridColumn(); myColumn.headerText = "Stato"; myColumn.width=50; myColumn.columnName="strecz"; dgmisure.addColumn(myColumn); myColumn =new DataGridColumn(); myColumn.headerText = "Descrizione"; myColumn.width=150; myColumn.labelFunction=mx.utils.Delegate.create(this,getDsc_Misura); dgmisure.addColumn(myColumn); myColumn =new DataGridColumn(); myColumn.headerText = "Calo"; myColumn.width=50; myColumn.labelFunction=mx.utils.Delegate.create(this,getTipo_Calo); dgmisure.addColumn(myColumn); for(var row=0;row<mx.core.Application.application.taglie.length;row++) { myColumn= new DataGridColumn(); myColumn.headerText = mx.core.Application.application.taglie[row]; myColumn.width=50; myColumn.columnName="ma"+(row+1)+"cz"; dgmisure.addColumn(myColumn); } } -- Flexcoders Mailing List FAQ: http://groups.yahoo.com/group/flexcoders/files/flexcodersFAQ.txt Search Archives: http://www.mail-archive.com/flexcoders%40yahoogroups.com Yahoo!
