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：
图一
图二
图三（1）
图三（2）
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：
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：
- 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。
- 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：
var qList = _db.SelectReportMonthDataForUnderDeco().ToList();
Store1.DataSource = qList;
Store1.DataBind();
- 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。
- 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：
var _headGroupRow = new HeaderGroupRow()
{
Columns =
{
new HeaderGroupColumn()
{
Header = "<font class='headRows1'></font>",
Align = Alignment.Center,
ColSpan = 1
}
}
};
_headGroupRow.Columns.Add(new HeaderGroupColumn()
{
Header =
string.Format("<font class='headRows1'>{0}</font>",
"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()
{
Header =
string.Format("<font class='headRows1'>{0}</font>",
GetEnglishMonth((_currentMonth + i).ToString())),
Align = Alignment.Center,

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。
先看页面代码（页面代码很简洁）：

<script type="text/javascript">

var fifterZero = function(value) {
if (value > 0)
return String.format(template, value);
else
return '';
};
function search() {
if (ddlArea.getValue() != '' && ddlYear.getValue() != '' && ddlMonth.getValue() != '') {
window.location.href = '<%=CurrentUrl %>' + "?newarea=" + escape(ddlArea.getValue()) + "&newyear=" + ddlYear.getValue() + "&newmonth=" + ddlMonth.getValue();
} else {
alert("请选择区域-年份-月份！");

仔细看起来，发现这个页面代码并没啥东西。只能隐约的看到，一个GridPanel底部放了一个GridPanel。看来真不是个东西。这里暂不作解释，继续贴码：

代码贴上去了，发现木有，也不是很多，这里我顺便解释解释：
-
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。
-
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。
-
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。
-
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…
