Fórum Problema com MasterPage #6161

Olá estou com fificuldade em visualizar um gridView que está dentro de uma página aspx de dentro de uma master page. O problema é que eu tenho dois Content e quando eu coloco qualquer outro componente como por exemplo um button ou escrevo alguma coisa aparece normalmente, o problema só é com o gridView.

já tentei mudar o grid de lugar e tmb não deu certo.
