通过这种方式，我们可以动态禁用或启用链接按钮或任何其他控件

protected void GridView1_RowEditing(object sender, GridViewEditEventArgs e)
    {  
      GridView1.EditIndex = e.NewEditIndex;
      BindGrid();
      /*if (<condtition)
       * {
       * */
      GridView1.Columns[3].Visible = false;

      // * }  
    }

protected void GridView1_RowUpdating(object sender, GridViewUpdateEventArgs e)
{
  //make it again visible 
   GridView1.Columns[3].Visible = true;

  // code to edit the rows
}

试试下面的代码，应该写在文件后面的代码中：

protected void GrivView1_RowDataBound(object sender, GridViewRowEventArgs e)
{
    LinkButtton lbtn = new LinkButtton();
    lbtn = (LinkButton)e.Row.FindControl("LinkButton1"); 
    lbtn.Enable = false;
}

我觉得这行代码就够了

 ((LinkButton)e.Row.Cells[1].Controls[0]).Visible = false;
