在GridView中隐藏或显示特定列有两个选项

选项1：使用单元格索引

 protected void GridView1_RowCreated(object sender, GridViewRowEventArgs e)
        {
          if (e.Row.RowType == DataControlRowType.DataRow)
                {
                if("your Condition")
                  {

                    e.Row.Cells[0].Control[0].Visible = false;//or true
                    }
                 }        
         }

选项2：通过GridView行控件集合循环

protected void GridView1_RowCreated(object sender, GridViewRowEventArgs e)
    {


            foreach (TableRow row in GridView1.Controls[0].Controls)
            {
             if("your Condition")
                      {
                      row.Cells[0].Control[0].Visible = false;
                      }
            }        
    }
