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：

        /// <summary>/// 绑定单选框组（最后一项为可编辑项，保持位置为ID+Hidden）/// </summary>/// <typeparam name="T">类类型</typeparam>/// <param name="lst">泛型集合</param>/// <param name="ID">复选框组ID</param>/// <param name="TextPropertyName">需要绑定的文本属性字段名（大写小都必须一致）</param>/// <param name="ValuePropertyName">需要绑定的值属性字段名（大写小都必须一致）</param>/// <param name="CheckedPropertyName">需要绑定的选择属性字段名（大写小都必须一致）</param>/// <param name="isCheckedPropertyName">是否是选择属性字段名，如果如false，则CheckedPropertyName表示选中的值</param>/// <param name="_ColumnsNumber">显示列数</param>/// <param name="_remark">备注项名称，如设置了此项，则可以填写该项备注</param>/// <param name="textlen">显示的文本长度</param>public static void BindRadioGroup<T>(System.Web.UI.UserControl _userControl, List<T> lst, string ID, string TextPropertyName, string ValuePropertyName, string CheckedPropertyName, bool isCheckedPropertyName, int? _ColumnsNumber, string _remark, int textlen){if (lst != null && lst.Count > 0){Control _control = _userControl.FindControl(ID);if (_control is RadioGroup){//该脚本实现弹框填写其他项，以下是参数//hiddenID：其他项的文本保存位置ID//chk：其他项的CheckBox//orgBoxLabel：原始的BoxLabelstring _setRemarkScript =@"function setChkRemark(hiddenID, chk, orgBoxLabel ,textlen) {if (chk.getValue()) {Ext.MessageBox.show({title: orgBoxLabel,msg: '请输入' + orgBoxLabel + '：',width: 300,buttons: Ext.MessageBox.OKCANCEL,multiline: true,value: hiddenID.getValue(),fn: function (btn, text) {var remark = text.replace(/(^\s*)|(\s*$)/g, '');if (btn == 'cancel')Ext.MessageBox.alert('温馨提示', '操作已取消。');else if (btn == 'ok') {hiddenID.setValue(remark);if (remark!='') chk.setBoxLabel(orgBoxLabel+':'+(remark.length>textlen? remark.toString().substring(0,textlen)+'...':remark));elsechk.setBoxLabel(orgBoxLabel);}}});}}";//注册函数_userControl.Page.ClientScript.RegisterStartupScript(_userControl.GetType(), "setChkRemark", _setRemarkScript, true);RadioGroup groupRadios = _control as RadioGroup;if (groupRadios == null)return;//groupRadios.SubmitValue = true;#region 【_ColumnsNumber】设置显示列数，为null则一行显示4列。_ColumnsNumber = _ColumnsNumber ?? 4;if (lst.Count <= _ColumnsNumber){groupRadios.ColumnsNumber = lst.Count;}else{groupRadios.ColumnsNumber = _ColumnsNumber.Value;}#endregiongroupRadios.Items.Clear();int i = 0;foreach (var item in lst){T t = item;Type type = t.GetType();Radio rdo = new Radio();rdo.ID = string.Format("{0}items{1}", ID, i);PropertyInfo TextProInfo = type.GetProperty(TextPropertyName);if (TextProInfo == null)ExtensionMethods.ThrowNullException(type, TextPropertyName);PropertyInfo ValueProInfo = type.GetProperty(ValuePropertyName);if (ValueProInfo == null)ExtensionMethods.ThrowNullException(type, ValuePropertyName);object objText = TextProInfo.GetValue(t, null);rdo.BoxLabel = objText == null ? string.Empty : objText.ToString();object objValue = ValueProInfo.GetValue(t, null).ToString();rdo.Tag = objValue == null ? string.Empty : objValue.ToString();rdo.InputValue = objValue == null ? string.Empty : objValue.ToString();if (!isCheckedPropertyName){if (rdo.Tag == CheckedPropertyName)rdo.Checked = true;groupRadios.Items.Add(rdo);i++;continue;}PropertyInfo CheckedProInfo = type.GetProperty(CheckedPropertyName);if (CheckedProInfo == null)ExtensionMethods.ThrowNullException(type, CheckedPropertyName);if ((CheckedProInfo.GetValue(t, null) ?? 0).ToString() == "1")rdo.Checked = true;groupRadios.Items.Add(rdo);i++;}groupRadios.Items[groupRadios.Items.Count - 1].Listeners.Check.Handler = "setChkRemark(#{" + ID + "Hidden},this,'" + _remark + "'," + textlen + ");";}else if (_control is System.Web.UI.WebControls.RadioButtonList){System.Web.UI.WebControls.RadioButtonList _rbl = _control as System.Web.UI.WebControls.RadioButtonList;_rbl.DataTextField = TextPropertyName;_rbl.DataValueField = ValuePropertyName;_rbl.DataSource = lst;_rbl.RepeatDirection = System.Web.UI.WebControls.RepeatDirection.Horizontal;//_rbl.RepeatLayout = RepeatLayout.Flow;_rbl.DataBind();if (!isCheckedPropertyName)_rbl.SelectedValue = CheckedPropertyName;}}}

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：

        /// <summary>/// 绑定单选框组/// </summary>/// <typeparam name="T">类类型</typeparam>/// <param name="lst">泛型集合</param>/// <param name="ID">复选框组ID</param>/// <param name="TextPropertyName">需要绑定的文本属性字段名（大写小都必须一致）</param>/// <param name="ValuePropertyName">需要绑定的值属性字段名（大写小都必须一致）</param>/// <param name="CheckedPropertyName">需要绑定的选择属性字段名（大写小都必须一致）</param>/// <param name="isCheckedPropertyName">是否是选择属性字段名，如果如false，则CheckedPropertyName表示选中的值</param>/// <param name="_ColumnsNumber">显示列数</param>public static void BindRadioGroup<T>(System.Web.UI.UserControl _userControl, List<T> lst, string ID, string TextPropertyName, string ValuePropertyName, string CheckedPropertyName, bool isCheckedPropertyName, int? _ColumnsNumber){if (lst != null && lst.Count > 0){Control _control = _userControl.FindControl(ID);if (_control is RadioGroup){RadioGroup groupRadios = _control as RadioGroup;if (groupRadios == null)return;#region 【_ColumnsNumber】设置显示列数，为null则一行显示4列。_ColumnsNumber = _ColumnsNumber ?? 4;if (lst.Count <= _ColumnsNumber){groupRadios.ColumnsNumber = lst.Count;}else{groupRadios.ColumnsNumber = _ColumnsNumber.Value;}#endregiongroupRadios.Items.Clear();int i = 0;foreach (var item in lst){T t = item;Type type = t.GetType();Radio rdo = new Radio();rdo.ID = string.Format("{0}items{1}", ID, i);PropertyInfo TextProInfo = type.GetProperty(TextPropertyName);if (TextProInfo == null)ExtensionMethods.ThrowNullException(type, TextPropertyName);PropertyInfo ValueProInfo = type.GetProperty(ValuePropertyName);if (ValueProInfo == null)ExtensionMethods.ThrowNullException(type, ValuePropertyName);object objText = TextProInfo.GetValue(t, null);rdo.BoxLabel = objText == null ? string.Empty : objText.ToString();object objValue = ValueProInfo.GetValue(t, null).ToString();rdo.Tag = objValue == null ? string.Empty : objValue.ToString();rdo.InputValue = objValue == null ? string.Empty : objValue.ToString();if (!isCheckedPropertyName){if (rdo.Tag == CheckedPropertyName)rdo.Checked = true;groupRadios.Items.Add(rdo);i++;continue;}PropertyInfo CheckedProInfo = type.GetProperty(CheckedPropertyName);if (CheckedProInfo == null)ExtensionMethods.ThrowNullException(type, CheckedPropertyName);if ((CheckedProInfo.GetValue(t, null) ?? 0).ToString() == "1")rdo.Checked = true;groupRadios.Items.Add(rdo);i++;}}else if (_control is System.Web.UI.WebControls.RadioButtonList){System.Web.UI.WebControls.RadioButtonList _rbl = _control as System.Web.UI.WebControls.RadioButtonList;_rbl.DataTextField = TextPropertyName;_rbl.DataValueField = ValuePropertyName;_rbl.DataSource = lst;_rbl.RepeatDirection = System.Web.UI.WebControls.RepeatDirection.Horizontal;//_rbl.RepeatLayout = RepeatLayout.Flow;_rbl.DataBind();if (!isCheckedPropertyName)_rbl.SelectedValue = CheckedPropertyName;}}}/// <summary>/// 绑定复选框组/// </summary>/// <typeparam name="T">类类型</typeparam>/// <param name="lst">泛型集合</param>/// <param name="ID">复选框组ID</param>/// <param name="TextPropertyName">需要绑定的文本属性字段名（大写小都必须一致）</param>/// <param name="ValuePropertyName">需要绑定的值属性字段名（大写小都必须一致）</param>/// <param name="CheckedPropertyName">需要绑定的选择属性字段名（大写小都必须一致）</param>public static void BindCheckGroup<T>(Control _userControl, List<T> lst, string ID, string TextPropertyName, string ValuePropertyName, string CheckedPropertyName, int?

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>/// 通过反射绑定下拉列表/// </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：

 _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。

        /// <summary>/// 给EXT.NET脚本赋予特权/// </summary>/// <param name="ResManager">ResourceManager</param>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();});}}

4）读取与赋值。

        /// <summary>/// 设置类型的属性值/// </summary>/// <typeparam name="T"></typeparam>/// <param name="t"></param>/// <param name="userControl">用户控件</param>public static void SetValues<T>(this System.Web.UI.Control userControl, T t){Type type = t.GetType();if (type.IsClass){var properties = type.GetProperties();foreach (var item in properties){if (item.CanWrite){System.Web.UI.Control control = userControl.FindControl("txt" + item.Name);if (control != null){string text = string.Empty;if (control is DateField){DateField _df = control as DateField;if (_df.IsEmpty){if (item.PropertyType.IsGenericType && item.PropertyType.GetGenericTypeDefinition() == typeof(Nullable<>))item.SetValue(t, null, null);//else//    item.SetValue(t, System.Data.DbType.DateTime., null);continue;}elsetext = _df.Text;}if (control is TextFieldBase)text = (control as TextFieldBase).Text.Trim();if (item.PropertyType.IsEnum){item.SetValue(t, Enum.ToObject(item.PropertyType, text), null);}else{//判断是否为可为空类型if (item.PropertyType.IsGenericType && item.PropertyType.GetGenericTypeDefinition() == typeof(Nullable<>)){if (item.PropertyType.GetGenericArguments()[0].Equals(typeof(DateTime)) && text == "0001/1/1 0:00:00")item.SetValue(t, null, null);elseitem.SetValue(t, Convert.ChangeType(text, item.PropertyType.GetGenericArguments()[0]), null);}elseitem.SetValue(t, Convert.ChangeType(text, item.PropertyType), null);}}}}}}/// <summary>/// 设置控件的属性值/// </summary>/// <typeparam name="T">类型</typeparam>/// <param name="t">类的对象</param>/// <param name="userControl">用户控件</param>public static void SetControlValues<T>(this System.Web.UI.UserControl userControl, T t){Type type = t.GetType();if (type.IsClass){var properties = type.GetProperties();foreach (var item in properties){System.Web.UI.Control control = userControl.FindControl("txt" + item.Name);if (control != null){if (control is TextFieldBase){TextFieldBase txt = control as TextFieldBase;object obj = item.GetValue(t, null);if (obj != null)txt.Text = obj.ToString();}else if (control is DisplayField){DisplayField txt = control as DisplayField;object obj = item.GetValue(t, null);if (obj != null)txt.Text = obj.ToString();}}}}}

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。

该出图的时候还是得出图啊。

首先需要验证的表单页面得挂上这段JS：

    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')});}}

然后：

            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>';}elseisCheckd=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：

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。
