protected void dgArticleClass_ItemDataBound(object sender, DataGridItemEventArgs e)
    {
        if (((e.Item.ItemType == ListItemType.Item) || (e.Item.ItemType == ListItemType.AlternatingItem)) || (e.Item.ItemType == ListItemType.EditItem))
        {
            e.Item.Attributes["onmouseover"] = "javascript:this.style.backgroundColor='#DFEAFD';";
            e.Item.Attributes["onmouseout"] = "javascript:this.style.backgroundColor='#ffffff';";
            TableCell cell = e.Item.Cells[6];
            LinkButton button = (LinkButton)cell.Controls[1];
            button.Attributes.Add("onclick", "return confirm('确定要删除这个栏目及其子栏目吗？');");
            TableCell cell2 = e.Item.Cells[7];
            LinkButton button2 = (LinkButton)cell2.Controls[0];
            button2.Attributes.Add("onclick", "return confirm('确定要清空这个栏目及其子栏目的软件吗？');");
        }
    }
当控件在DataView或DataGrid里时：
      btn.Attributes.Add("onclick","javascript:return confirm('确定删除吗？')");
在控件里需要用到别的控件来存状态以便操作
      例如：Button,label 控件  
       Button lbtnSetVIP = (LinkButton)sender;  //sender是object对象之一
      找到它>>
       label   lb  =  (label)e.Row.FindCcontrol("lbXX");  //lbXX是ID号
    
      然后此Button 控件对象通过lXX找到该控件 (找到它的父级控件)
     
       label  lbvip  =  new  label();
       lbvip =  (label)lbtnSetVIP .Parent.FindControl("lbXX");

      label  lbid = new label();
      实例化label 在这里是为了存这一项的主键以便操作：
      >> update_member = "update member set isvip = 1 where id =" + lbid.Text;
