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：

/// <summary>

/// </summary>
/// <typeparam name="T">类类型</typeparam>
/// <param name="lst">泛型集合</param>
/// <param name="ID">下拉列表ID</param>
/// <param name="TextPropertyName">文本属性名</param>
/// <param name="ValuePropertyName">值属性名</param>
/// <param name="_SelectValue">选择的值</param>
public static void BindComobox<T>(Control _userControl, List<T> lst, string ID, string TextPropertyName, string ValuePropertyName, string _SelectValue)
{
    if (lst != null && lst.Count > 0)
    {
        ComboBox _cbos = _userControl.FindControl(ID) as ComboBox;
        if (_cbos == null)
            return;
        _cbos.Items.Clear();
        foreach (var item in lst)
        {
            T t = item;
            Type type = t.GetType();
            ListItem _li = new ListItem();
            //文本属性
            PropertyInfo TextProInfo = type.GetProperty(TextPropertyName);
            if (TextProInfo == null)
                ExtensionMethods.ThrowNullException(type, TextPropertyName);
            //值属性
            PropertyInfo ValueProInfo = type.GetProperty(ValuePropertyName);
            if (ValueProInfo == null)
                ExtensionMethods.ThrowNullException(type, ValuePropertyName);
 
            object objText = TextProInfo.GetValue(t, null);
            _li.Text = objText == null ? string.Empty : objText.ToString();
            object objValue = ValueProInfo.GetValue(t, null).ToString();
            _li.Value = objValue == null ? string.Empty : objValue.ToString();
            _cbos.Items.Add(_li);
        }
        if (!string.IsNullOrEmpty(_SelectValue))
            _cbos.SelectedItem.Value = _SelectValue;
    }
}

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：

1
2
3
4
5
_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。

public static void BuildAllPrivilegesForExtNET(this ResourceManager ResManager)
{
    if (!X.IsAjaxRequest)
    {
        SPSecurity.RunWithElevatedPrivileges(
            delegate()
            {
                ResManager.RenderScripts = ResourceLocationType.Embedded;
                ResManager.BuildScripts();
                ResManager.RenderStyles = ResourceLocationType.Embedded;
                ResManager.BuildStyles();
            }
        );
    }
}

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。

var valCss = '';
 
function showMsg(title, content, cs) {
 
    if (valCss != cs) {
 
        valCss = cs;
 
        Ext.net.Notification.show({
 
            hideFx: {
 
                fxName: 'switchOff',
 
                args: [{}]
 
            },
 
            showFx: {
 
                args: [
 
                          'C3DAF9',
 
                          1,
 
                          {
 
                              duration: 2.0
 
                          }
 
                      ],
 
                fxName: 'frame'
 
            },
 
            iconCls: cs,
 
            closeVisible: true,
 
            html: content,
 
            title: title + '   ' + new Date().format('g:i:s A')
 
        });
 
    }
 
}

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：

  1. 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。
  2. 支持页面上防止保存提交按钮，存在与否也没关系。
  3. 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：
