  2.   

    GridView1.Rows[行].Cells[列].Text
    刚才写错了。呵呵。参照这个吧。
      

  3.   

            msfstr = GridView1.Rows[GridView1.SelectedIndex].Cells[0].Text;
      

  4.   

    GridView1.Rows[行号].Cells[列号].Text 
      

  5.   

    我想获得选中的那行的第一列的值
    用的
    gvwDept.SelectedRow.Cells[0].Text但是报未将对象引用到实例是怎么回事啊？
    有数据的
