Answer 1

 for (int i = 0; i < this.GridView1.Rows.Count; i++)
        {
            if (((CheckBox)this.GridView1.Rows[i].Cells[0].FindControl("CheckBox1")).Checked == true)
            {
             //你要输出的内容
            }
        }

Answer 2

不行...断点进不来~~ 怀疑 FindControl("CheckBox1") 有问题

Answer 3

在page_load的时候被刷新了吧？
