The app I am building requires a table of about 10x8. This is not a small table, but I wouldn't call it an excessivley large table.
My computer is a laptop but its not that slow. I have never had any performance issues with it.
Exceuting the following code to build my grid programatically takes aprox 6 seconds
var row:GridRow=new GridRow();
var item:GridItem=new GridItem();
var text:TextArea=new TextArea();
Doing anything with this component, like moving it to another place etc is also fairly slugish. Is this expected behaviour? Are spreadsheets beyond the scope of flex?
Building a spreadsheet out of containers would not be recommended. I would extend DataGrid or maybe just ListBase.
