Hello,

I found my problem but I couldn't find the solution. I need to do a grid that have doublebox for each line, so the user can change the quantity of each item direct in the grid, the problem is when I load the data and the render creates the doublebox the browser takes to long to render the grid, if I remove the doublebox the performance is much more faster.

This is the my RowRenderer's code:

new Label(codigoInteligente).setParent(row);
new Label(nomeCor).setParent(row);
new Label(quantidade.toString()).setParent(row);

// The above code is responsible for the bad performance
Doublebox quantidadeAdd = new Doublebox(0);
quantidadeAdd.setWidth("90px");
quantidadeAdd.setConstraint("no negative");
quantidadeAdd.setParent(row);

Doublebox preco = new Doublebox(0);
preco.setWidth("60px");
preco.setConstraint("no negative");
preco.setParent(row);

But I need to be able to edit the quantity (and price) for each row. Is there a faster (about the rendering) way that I could do this?

FYI, my app needs to support IE7+ and Firefox only.
