MinWidth

Por padrão o valor do MinWidth é 20, e ao dar o Resize, se a quantidade de colunas da grid for um pouco grande, ele vai ajustar e chegar ate o valor do MinWidth.
Acredito que a maioria das vezes esse recurso é utilizado para campos como descrições, nome, endereço, etc,
Sugiro pegar o valor definido do Width e popular o valor do MinWidth, assim o que estiver definido em tempo de projeto vai ser o tamanho mínimo.
Obrigado.
