在上一篇《EXT.NET高效开发（一）——概述》中，大致的介绍了一下EXT.NET。那么本篇就要继续完成未完成的事业了。说到高效开发，那就是八仙过海各显神通。比如使用代码生成器，这点大家可以参考我的这篇帖子《CodeSmith系列（三）——使用CodeSmith生成ASP.NET页面》。本人是比较推崇批量化生产的。当然，本篇的重点不在这，看过标题的人都知道。
在使用EXT.NET的时候（当然不仅仅是EXT.NET），总是要做很多重复的事，于是封装一些实用的函数可以一劳永逸呀。
1）单选框和复选框.
看图说话开始了，如图
当选择其他的时候，出框框填写数据。在实际需求中，很多选择项都不是只有A、B、C、D，往往还能自己自定义。遇到这种需求的，每次加个框框跟后面既麻烦又不方便布局，于是秉着不重复造轮子的原则，定义了以下函数：

这样调用起来就方便了，如： |

ExtControlHelper.BindCheckGroup(this, _db.SelectGeneralFromTableINFO(ShopID, CurrentFormID, "TerminationReason").ToList() , "cblTerminationReason", "AttributeValue", "AttributeID", "CheckValue", 4, "其他", 8); |
不过别忘了在页面上丢一个“<ext:Hidden ID="cblTerminationReasonHidden" runat="server" />”。
为了方便，本人又定义了以下几个函数：

2）下拉列表。
无图无真相，果断上图。
绑定下拉列表，在这里，本人也封装了以下。如下面代码：

其实还有一种方式可以绑定，但是本人更喜欢这种。比如通过Store：

_store = new Store { ID = string.Format("_store{0}", Guid.NewGuid().ToString("N")), IDMode = IDMode.Static }; _jsonReader = new JsonReader(); _jsonReader.Fields.Add(new RecordField("text", RecordFieldType.String)); _jsonReader.Fields.Add(new RecordField("value", RecordFieldType.String)); _store.Reader.Add(_jsonReader); |
然后再加上自己定义的URL和参数，定义几个参数，封装一下，也可以通用，这里我就不继续写下去了。
3）SharePoint中，给EXT.NET赋权。
这段代码，提供给需要的人吧。当初这问题把我折磨得快疯狂了。还好想到了这么一个解决方案。

上面的代码进行了可为空类型的判断，这点需要注意。
5）设置通用的表单验证脚本。

if (!string.IsNullOrEmpty(_fp.Listeners.ClientValidation.Handler)) return;_fp.Listeners.ClientValidation.Handler = @" var isCheckd=valid;var msgs;var msg=''; if(typeof(ValCustomValidator)=='function') { msgs=ValCustomValidator(false,valid); if(typeof(msgs.IsVal)!='undefined') { isCheckd=msgs.IsVal; if(msgs.Message!='') msg='<span style=\'color:red;\'>'+msgs.Message+'</span>'; } else isCheckd=msgs; } if(typeof(#{btnSave})!='undefined' && #{btnSave}!=null)#{btnSave}.setDisabled(!isCheckd); if(typeof(#{btnSumbit1})!='undefined' && #{btnSumbit1}!=null)#{btnSumbit1}.setDisabled(!isCheckd); var valCs=isCheckd ? 'valaccept' : 'valexclamation'; if (msg=='') msg=isCheckd ? '<span style=\'color:green;\'>验证通过，可以提交数据</span>' : '<span style=\'color:red;\'>输入有误，请检查标红的输入项。</span>'; this.getBottomToolbar().setStatus({text :msg, iconCls: valCs});showMsg('温馨提示',msg,valCs); "; |
顺便解释一下：
- 支持在页面上写自定义验证函数“ValCustomValidator”。存在与否都不会引发异常。
- 支持页面上防止保存提交按钮，存在与否也没关系。
- 你还可以根据自己的情况自定义。
因为这里是通用的，比如默认给每一个表单使用这个验证脚本。那么如何实现自定义验证呢？先欣赏两幅美图：
然后右下角就来提示了：
这里再贴上具体的JS：

看到上面那一串ID没，这就是不使用IDMode的后果。因为刚开始接触，未发现有这么个好东东。
好了，今天就到此为止吧，我们还会见面的。我上面用了一些反射，大家都说反射性能怎么样怎么样，但是这点消耗有时大可不必担心，不过有些还是可以优化的，比如绑定下拉列表，使用Store结合HttpProxy的话，就完全不需要用反射了。只是每次绑定的时候，代码里面要调用下，然后Httphandler类也要写点代码。
当然我封装的并不止这一些，但是只适合我自己的系统，就不方便拿出来了。
兄弟我先抛块砖，有玉的赶紧砸过来吧。
