EXT.NET复杂布局（二）—

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：

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：

 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：

                    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,ColSpan = 4,});}_headGroupRow.Columns.Add(new HeaderGroupColumn(){Header =string.Format("<font class='headRows1'>{0}</font>","Certificated"),Align = Alignment.Center,ColSpan = 4,});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。

先看页面代码（页面代码很简洁）：

<%@ Register Assembly="Ext.Net" Namespace="Ext.Net" TagPrefix="ext" %>
<style type="text/css">.headRows1{color: Green;font-weight: bolder;}.headRows2{color: Purple;font-weight: bolder;}
</style><script type="text/javascript">var template = '<b style="color:blue;">{0}</b>';var fifterZero = function(value) {if (value > 0)return String.format(template, value);elsereturn '';};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！");}}
</script><div style="margin-left:10px;"><ext:ResourceManager ID="ResourceManager1" runat="server" /><ext:FieldSet Collapsible="true" ID="Panel1" Border="true" Width="800" runat="server"Title="搜索条件" AutoHeight="true"><Items><ext:TableLayout ID="TableLayout1" runat="server" Columns="3"><Cells><ext:Cell><ext:ComboBox ID="ddlArea" Width="235" IDMode="Static" FieldLabel="区域" Editable="false"runat="server" /></ext:Cell><ext:Cell><ext:ComboBox ID="ddlYear" Width="235" IDMode="Static" FieldLabel="年份" Editable="false"runat="server" /></ext:Cell><ext:Cell><ext:ComboBox ID="ddlMonth" Width="235" IDMode="Static" FieldLabel="月份" Editable="false"runat="server" /></ext:Cell></Cells></ext:TableLayout></Items><BottomBar><ext:Toolbar ID="tbSearch" runat="server"><Items><ext:Button ID="btnSearch" runat="server" Text="查询" Icon="ArrowRefresh" LabelAlign="Left"Type="Button" AutoPostBack="false"><Listeners><Click Handler="search();" /></Listeners></ext:Button></Items></ext:Toolbar></BottomBar></ext:FieldSet><ext:GridPanel ID="GridPanel1" AutoScroll="true" TrackMouseOver="true" runat="server"ColumnLines="true" StripeRows="true" AutoHeight="true" Title="ShopStatus" Icon="Date"><Store><ext:Store ID="Store1" ShowWarningOnFailure="false" AutoLoad="true" runat="server" /></Store><LoadMask ShowMask="true" /><ColumnModel ID="ctl120" /><View><ext:GroupingView ID="gvColumns" runat="server" /></View><BottomBar><ext:Toolbar ID="Toolbar1" runat="server" Margins="0,0,0,0"><Items><ext:GridPanel ID="gpItems" AutoScroll="true" TrackMouseOver="true" runat="server" Margins="0,0,0,0"HideHeaders="true" ColumnLines="true" StripeRows="true" AutoHeight="true" Title="Jun"Icon="DateGo"><Store><ext:Store ID="storeItems" ShowWarningOnFailure="false" AutoLoad="true" runat="server" /></Store><LoadMask ShowMask="true" /><ColumnModel /></ext:GridPanel></Items></ext:Toolbar></BottomBar></ext:GridPanel>
</div><script type="text/javascript">Ext.onReady(function() {$(function() {setTimeout("setLabelClass()", 300);});});function setLabelClass() {$("table.x-table-layout").attr("width", "100%");} 
</script>

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…
