DataTemplateSelector(项目)
今天记录一下前端项目中使用DataTemplateSelector的步骤。
首先看项目目录：
这里有一个FiledType.cs文件，还有一个RefineSearch.xaml以及其后台程序。FiledType.cs里是关于要使用的类的属性的定义，里面有一个类的构造，这里可以看到FiledType的类的构造函数，里面的参数是我们后面要做的ComboBox里面items类型所有的属性。即ComboBox里每一项都是一个复杂的FiledType类型，而且里面包含如下这些属性信息。
FieldType(int sortOrder, string readableName, string internalName, string dataType)
如果选择ComboBox里某一选项的dataType是string类型，那么后面只出现一个textbox，如果是其他类型比如double，那么出现两个textbox,用来输入MaxDoubleInput和MinDoubleInput。
FiledType.cs 文件
using System; using System.Collections.Generic; using System.Linq; using System.Text; using System.ComponentModel; namespace PfgDbTestHarness { public class FieldType : INotifyPropertyChanged //FieldType类型数据有任何改变将自动通知CLR更新Textbox后面的数据 { public event PropertyChangedEventHandler PropertyChanged; private string _readableName; public string ReadableName { get { return _readableName; } set { if (_readableName != value) { _readableName = value; OnPropertyChanged("ReadableName"); } } } public string InternalName { get; set; } public string DataType { get; set; } private string _stringInput; //这个是Ryan帮我加的。用来保存在Textbox里键入的数据：string类型或者double类型的MaxDoubleInput和MinDoubleInput public string StringInput { get { return _stringInput; } set { if (_stringInput != value) { _stringInput = value; OnPropertyChanged("StringInput"); } } } private string _minDoubleInput; public string MinDoubleInput { get { return _minDoubleInput; } set { if (_minDoubleInput != value) { _minDoubleInput = value; OnPropertyChanged("MinDoubleInput"); } } } private string _maxDoubleInput; public string MaxDoubleInput { get { return _maxDoubleInput; } set { if (_maxDoubleInput != value) { _maxDoubleInput = value; OnPropertyChanged("MaxDoubleInput"); } } } private readonly int _sortOrder; public int SortOrder { get { return _sortOrder; } } public override string ToString() { return ReadableName; } public FieldType(int sortOrder, string readableName, string internalName, string dataType) //一个FiledType类型的对象有以下4个属性的信息 { _sortOrder = sortOrder; ReadableName = readableName; InternalName = internalName; DataType = dataType; } public virtual void OnPropertyChanged(string property) { if (PropertyChanged != null) { PropertyChanged(this, new PropertyChangedEventArgs(property)); } } } }
下面我们要实现ComboBox里选择的item的dataType是string类型的，后面自动切换成一个TextBox的模板。选择的item为其他类型则切换成两个Textbox的模板（这里只给出了item的dataType是Double的情况，其他类型程序不全。）
定义dataTypeTemplateSelecter类。

制作完了C#后台dataTypeTemplateSelecter类后，我们就可以和前台xaml链接。
