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。
