• EXT.NET复杂布局(二)——报表


    前面提到过工作台(《EXT.NET复杂布局(一)——工作台》)了,不知道各位看过之后有什么感想。这次就介绍介绍使用EXT.NET画几个报表。

    看图写作从小学就开始了,如图:

    各位看官,不要以为这报表画起来很难,其实使用EXT.NET来画的话,还是挺简单方便的。

    1)下面就从图一开始。

    这个报表实现,本人采用的是最原始的手写代码(之所以这么说,是因为没怎么偷懒,老老实实的写的,因为这是刚接触EXT.NET的时候画的)

    先上代码,然后再说话吧。其实注释挺全的,所以也不需要说什么话了:

    然后只需要完善Httphandler类就好了。这个报表只是在列头的组合上稍微有点难度,其实也没难度,看我的代码,应该是很清晰的。

    2)现在开始说第二个报表了。再看看图二:

    image

    这个报表难度其实也不大,主要有这么几个地方值得注意:

    • 列头合并。前面以后说过了。很简单的配置。
    • 列合计。待会看源码。
    • 过滤掉0。如果是0,则什么都不显示,否则显示蓝色的数字。因为这个报表测试数据干了,我又懒,所以大家想象一下数据就好了。据说画饼充饥是有效果的,当然不是我说的。信不信由你,反正我是相信了。
    • 注意列头的HTML编码。别把任意字符都往列头加,列头会表示有压力的,并且会导致页面空白而且无异常。所以注意把特殊字符进行编码。

    这个报表虽然复杂了一点点,但是也很简单。现在一起来ViewCode:

    该说的都说了,注释也懒得写了。现在想说的是下面几点:

      1. 首先来看记录集(RecordField)。注意字段的类型(Type="Int")。比如你的数据中有DateTime类型、Int类型的数据,最好设置下类型,这样的话,就可以避免出现undefined。而且也方便格式转换。
      2. Store。这个Store为什么没有设置URL呢?在《EXT.NET高效开发(一)——概述》我说过,“7)数据交换更简单”。应该是“数据交互”,本人比较懒,只在这里更正申明下好了,我也是刚看到。这里的Store,是在后台赋值的。如下面代码:
    1
    2
    3
    var qList = _db.SelectReportMonthDataForUnderDeco().ToList();
                       Store1.DataSource = qList;
                       Store1.DataBind();
      1. 统计怎么算的?注意updateTotal函数。“总计”两个字是怎么加上去的,答曰:“敲上去的”。再注意BottomBar(想当然的,这就是底部工具条),这里就是显示统计的数据的。
      2. 估计看官会有这么一个疑问,列头分组怎么分的,木有见代码。代码是有的,只是还木有贴出来,因为我写在后台,这种方式也挺直观方便的。当然萝卜白菜各有所爱了:

                          "Under Deco."),
        Align = Alignment.Center,
        ColSpan = 4,
    });
    var _currentMonth = Convert.ToInt32(qList.First().monthnum.Trim());
    for (int i = 0; i < 3; i++)
    {
        _headGroupRow.Columns.Add(new HeaderGroupColumn()

    gvColumns.HeaderGroupRows.Add(_headGroupRow);

    这个就说到这里了。

    3)这个相对来说,比上两个都复杂。但是我画起来,比上两个都快。一个是更熟练了,第二个是生成了很多东西。

    代码贴上去了,发现木有,也不是很多,这里我顺便解释解释:
    1. 点击【查询】按钮后,刷新页面获取数据。当然您也可以改成不刷新的,也很简单的,这里我是为了更简单。
      不过在这方面,我要说一下:你可以使用X.IsAjaxRequest来判断是否是EXT的Ajax请求,别重复执行了Page_load事件里面的代码。
    2. 数据源是直接绑的,使用的是DataTable。然后在绑定的时候,使用LINQ to DataTable进行了过滤。这个报表不会有多少数据。
      当然如果你喜欢2.0的话,也可以用那个Select啊,DataView的RowFilter等来过滤。
    3. 数据集、字段、列是动态加的,列头是手动写的。因为列头不一样,而且有特殊字符。也就是说,如果可以,你完全可以动态生成整个GridPanel。
    4. 最后说点。Extjs与JQuery框架是不冲突的,井水不犯河水。
    封装点函数,整个动态生成,也是一种高效的开发,这也是我EXT.NET高效开发系列所推崇的(EXT.NET高效开发(二)——封装函数)。
    也许有人会说点性能问题什么的,我个人认为,生活总是有所取舍的,至于如何取舍,就需要根据个人的环境来判断了,不要捡了芝麻丢了西瓜就行了。
    再套用一句,勿以BUG小而为之,勿以Code小而不为。
    总算写完了。有时间的话,我会继续…
