结合AspNetPager6.0无刷新分页,排序(dataGrid)--代码讲解一

上次的给出了演示效果,这次就把代码一些细节说明一下.
首先说明下这个例子用到的结构和基类:
   1、具有dataGrid的页面继承了ListDataPage这个类，而ListDataPage类又继承了PageBase这个页面类。
         其中PageBase你可以写一些页面上最基本的属性，方法等。
         基本的代码如下：

   里面有alert这个可以基于ajax页面中实现js中alert功能，有权限控制功能，这些可以结合自己的项目写一些常用方法，还有css页面加载和常用js脚本加载等公用方法。

}

   其中InitAspNetPager(AspNetPager po_Pager)这个方法是初始化分页控件的属性，如PageSize页面初始记录数等，排序方面我们把它放到SortDirection这个属性中，其实也就是一个ViewState保存其状态。DataGridSortData这个方法是在触发排序事件的时候加载这个方法，改变其DataGrid的升降标志。PagerBindDate这个方法是在页面改变的时候改变分页控件的自定义文本区的显示，达到同步页面记录数的显示信息。（可以自己需要修改）
其他重载OnPreRender、OnInit方法中，我加载了subModal.css样式，和submodalsource.js脚本，是因为这里我用了 http://gabrito.com/files/subModal/这个网站上提供的代码替换弹出框。其中我修改了一个地方，

      if  (callReturnFunc == true ) // 主窗口上建立一个回调方法 
     {
        document.getElementById("TextBox1").value="reload";
        __doPostBack("TextBox1","")
    }

我在页面上加入一个TextBox1，作为是否回发标志。这个后面会更清楚。
2、页面上面基本上用到的控件有：ScriptManager，UpdatePanel，UpdateProgress，DataGrid，AspNetPager1，TextBox1（刚才提到是否回发标志），txt_delid（删除回复标志），btnAddNew（弹出新增页面）。其中UpdatePanel定义了3个触发器AsyncPostBackTrigger，第一个是AspNetPager1分页控件了，监听事件PageChanged，第2个就是当新增页面关闭（增加成功情况）时要对父页面（当前这个页面）进行回发，用到的是TextBox1，其事件TextChanged，最后一个就是删除事件用到的txt_delid的TextChanged，因为我这个删除按钮（其实是张图片而已）放在DataGrid中的模板中，动态绑定它的onclick 事件，回发txt_delid的改变值，好让服务端删除记录后刷新局部。

好了，页面代码如下：
