1.創(chuàng)建一個(gè)CustomPropertyGrid自定義控件：

<UserControl
  x:Class="PropertyGridDemo.PropertyGridControl.CustomPropertyGrid"
  xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
  xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
  xmlns:d="http://schemas.microsoft.com/expression/blend/2008"
  xmlns:dxprg="http://schemas.devexpress.com/winfx/2008/xaml/propertygrid"
  xmlns:local="clr-namespace:PropertyGridDemo.PropertyGridControl"
  xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"
  d:DesignHeight="300"
  d:DesignWidth="300"
  mc:Ignorable="d">
  <UserControl.Resources>
    <ResourceDictionary>
      <ResourceDictionary.MergedDictionaries>
        <!-- 資源字典 -->
        <ResourceDictionary Source="../PropertyGridControl/DynamicallyAssignDataEditorsResources.xaml" />
      </ResourceDictionary.MergedDictionaries>
    </ResourceDictionary>
  </UserControl.Resources>
  <Grid>
    <!-- PropertyDefinitionStyle:定義屬性描述的風(fēng)格模板 -->
    <!-- PropertyDefinitionTemplateSelector:定義一個(gè)模板選擇器，對(duì)應(yīng)一個(gè)繼承自DataTemplateSelector的類 -->
    <!-- PropertyDefinitionsSource:定義一個(gè)獲取數(shù)據(jù)屬性集合的類，對(duì)應(yīng)一個(gè)自定義類（本Demo中對(duì)應(yīng)DataEditorsViewModel） -->
    <dxprg:PropertyGridControl
      x:Name="PropertyGridControl"
      Margin="24"
      DataContextChanged="PropertyGridControl_DataContextChanged"
      ExpandCategoriesWhenSelectedObjectChanged="True"
      PropertyDefinitionStyle="{StaticResource DynamicallyAssignDataEditorsPropertyDefinitionStyle}"
      PropertyDefinitionTemplateSelector="{StaticResource DynamicallyAssignDataEditorsTemplateSelector}"
      PropertyDefinitionsSource="{Binding Path=Properties, Source={StaticResource DemoDataProvider}}"
      ShowCategories="True"
      ShowDescriptionIn="Panel" />
  </Grid>
</UserControl>

該控件使用的資源字典如下：

      IsReadOnly="True"
      IsTabStop="False" />
  </DataTemplate>

  <!-- 設(shè)置控件的全局樣式和數(shù)據(jù)綁定 -->
  <Style x:Key="DynamicallyAssignDataEditorsPropertyDefinitionStyle" TargetType="dxprg:PropertyDefinition">

  </Style>

  <!-- 測(cè)試直接從DataTemplate獲取控件 -->
  <DataTemplate x:Key="SliderTemplate" DataType="local:SliderExtend">

  </DataTemplate>

  <DataTemplate x:Key="ComboBoxEditItemTemplate" DataType="Tuple">

  </DataTemplate>
</ResourceDictionary>

    /// <summary>

    public override DataTemplate SelectTemplate(object item, DependencyObject container)
    {
      _element = (RootPropertyDefinition)container;
      DataTemplate resource = TryCreateResource(item);

      if (customUIAttribute == null) return null;
      var customUIType = customUIAttribute.CustomUI;
      return CreatePropertyDefinitionTemplate(customUIAttribute);
    }

    /// <summary>

      ct.VisualTree = new FrameworkElementFactory(typeof(StackPanel));
      ct.VisualTree.SetValue(StackPanel.DataContextProperty, GetDataContext(customUIAttribute.DataContextPropertyName));

    /// <summary>

    private DataTemplate CreateComboBoxEditTemplate(CustomUIAttribute customUIAttribute)
    {
      DataTemplate template = new DataTemplate();
      template.VisualTree = new FrameworkElementFactory(typeof(DockPanel));
      template.VisualTree.SetValue(DockPanel.DataContextProperty, GetDataContext(customUIAttribute.DataContextPropertyName));

      return template;
    }

    /// <summary>

    private DataTemplate CreatePropertyDefinitionTemplate(CustomUIAttribute customUIAttribute)
    {
      DataTemplate dataTemplate = new DataTemplate();
      DataTemplate cellTemplate = null;//單元格模板
      FrameworkElementFactory factory = new FrameworkElementFactory(typeof(PropertyDefinition));
      dataTemplate.VisualTree = factory;
      switch (customUIAttribute.CustomUI)
      {
        case CustomUITypes.Slider:

      {

      }
      else

        return null;
      }
      return dataTemplate;
    }
  }
}
using System.Collections.Generic;
using System.ComponentModel;
using System.Linq;

namespace PropertyGridDemo.PropertyGridControl
{
  /// <summary>
  ///初始化所有屬性并調(diào)用模板選擇器進(jìn)行匹配
  /// </summary>

  {
    public IEnumerable<PropertyDescriptor> Properties { get { return TypeDescriptor.GetProperties(typeof(TestPropertyGrid)).Cast<PropertyDescriptor>(); } }
  }
}

3.編寫(xiě)一個(gè)可用于構(gòu)建模板的屬性 CustomUIType：

using System;

namespace PropertyGridDemo.PropertyGridControl
{
  public class CustomUIType
  {

  }

  public enum CustomUITypes
  {
    Slider,
    ComboBoxEit,
    SpinEdit,
    CheckBoxEdit
  }

  [AttributeUsage(AttributeTargets.Property)]
  internal class CustomUIAttribute : Attribute
  {
    public string DataContextPropertyName { get; set; }
    public CustomUITypes CustomUI { get; set; }
    /// <summary>
    /// 自定義控件屬性構(gòu)造函數(shù)
    /// </summary>
    /// <param name="uiTypes">The UI types.</param>
    /// <param name="dataContextPropertyName">Name of the data context property.</param>
    internal CustomUIAttribute(CustomUITypes uiTypes, string dataContextPropertyName)
    {
      CustomUI = uiTypes;
      DataContextPropertyName = dataContextPropertyName;
    }
  }

}

4.編寫(xiě)對(duì)應(yīng)的DataContext類 TestPropertyGrid:

using DevExpress.Mvvm.DataAnnotations;
using System;
using System.ComponentModel;
using System.ComponentModel.DataAnnotations;
using System.Timers;
using System.Windows;

namespace PropertyGridDemo.PropertyGridControl

    private SliderUIDataContext _countSource = null;
    private ComboBoxEditDataContext _comboSource = null;
    private double _value=1;

    public TestPropertyGrid()
    {
      Password = "1111111";
      Notes = "Hello";
      Text = "Hello hi";
    }

    [Browsable(false)]
    public SliderUIDataContext CountSource
    {
      get
      {
        if (_countSource != null)
        {

          return _countSource;
        }
        else
        {
          _countSource = new SliderUIDataContext(0, 100, Count, 0.1, 1);
          _countSource.PropertyChanged += (object o, PropertyChangedEventArgs e) =>
          {
            this.Count = _countSource.Value;
          };
          return _countSource;
        }
      }
    }

    [Browsable(false)]
    public ComboBoxEditDataContext ComboSource
    {
      get
      {
        if(_comboSource==null)
        {
          _comboSource =new ComboBoxEditDataContext(ComboBoxEditItemSource.TestItemSource,Value);
          _comboSource.PropertyChanged += (object o, PropertyChangedEventArgs e) =>
           {
             this.Value =Convert.ToDouble(_comboSource.EditValue.Item2); 
           };
          
        }
        return _comboSource;
      }
    }

    [Display(Name = "SliderEdit", GroupName = "CustomUI")]
    [CustomUI(CustomUITypes.Slider, nameof(CountSource))]
    public double Count
    {
      get => _count;
      set
      {
        _count = value;
        CountSource.Value = value; 
        RaisePropertyChanged(nameof(Count));
      }
    }

    [Display(Name = "ComboBoxEditItem", GroupName = "CustomUI")]
    [CustomUI(CustomUITypes.ComboBoxEit, nameof(ComboSource))]
    public double Value
    {
      get => _value;
      set
      {
        if (_value == value) return;
        _value = value;
        //ComboSource.Value = value;
        RaisePropertyChanged(nameof(Value));
      }
    }

    [Display(Name = "Password", GroupName = "DefaultUI")]
    public string Password { get; set; }

    [Display(Name = "TextEdit", GroupName = "DefaultUI")]
    public string Text { get; set; }

    [Display(Name = "Notes", GroupName = "DefaultUI")]
    public string Notes { get; set; }


    [Display(Name = "Double", GroupName = "DefaultUI")]
    [DefaultValue(1)]
    public double TestDouble { get; set; }

    [Display(Name = "Items", GroupName = "DefaultUI")]
    [DefaultValue(Visibility.Visible)]
    public Visibility TestItems { get; set; }
  }

  public static class DynamicallyAssignDataEditorsMetadata
  {
    public static void BuildMetadata(MetadataBuilder<TestPropertyGrid> builder)
    {
      builder.Property(x => x.Password)
        .PasswordDataType();

      builder.Property(x => x.Notes)
        .MultilineTextDataType();
    }
  }
}

 該類中用到的其他類主要有以下幾個(gè)，以下幾個(gè)類主要用于數(shù)據(jù)綁定：

    public Tuple<string,object> EditValue
    {
      get => _editValue;
      set
      {
        if (_editValue == value) return;
        _editValue = value;
        RaisePropertyChanged(nameof(EditValue));
      }
    }

    public object Value
    {
      set
      {
        EditValue = ItemSource.FirstOrDefault(x => x.Item2.Equals(value));
      }
    }

    /// <summary>

  }
}
using System.ComponentModel;

namespace PropertyGridDemo.PropertyGridControl
{
  public class PropertyDataContext:INotifyPropertyChanged
  {
    /// <summary>

    public event PropertyChangedEventHandler PropertyChanged;

    /// <summary>

    public virtual void RaisePropertyChanged(string propertyName)
    {
      PropertyChanged?.Invoke(this, new PropertyChangedEventArgs(propertyName));
    }
  }
}
using System;

namespace PropertyGridDemo.PropertyGridControl
{
  internal static class ComboBoxEditItemSource
  {
    internal static Tuple<string, object>[] TestItemSource = new Tuple<string, object>[] {
      new Tuple<string, object>("1",1),
      new Tuple<string, object>("2",2),
      new Tuple<string, object>("3",3)
    };
  }
}

5.將以上的CustomPropertyGrid丟進(jìn)容器中即可，這里我直接用Mainwindow來(lái)演示：

<Window
  x:Class="PropertyGridDemo.MainWindow"
  xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
  xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
  xmlns:PropertyGridControl="clr-namespace:PropertyGridDemo.PropertyGridControl"
  xmlns:d="http://schemas.microsoft.com/expression/blend/2008"
  xmlns:local="clr-namespace:PropertyGridDemo"
  xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"
  Title="MainWindow"
  Width="525"
  Height="350"
  WindowState="Maximized"
  mc:Ignorable="d">
  <Grid Margin="10">
    <Grid.ColumnDefinitions>
      <ColumnDefinition Width="259*" />
      <ColumnDefinition Width="259*" />
    </Grid.ColumnDefinitions>

    <TextBox
      x:Name="OutputBox"
      Grid.ColumnSpan="1"
      HorizontalScrollBarVisibility="Auto"
      ScrollViewer.CanContentScroll="True" />
    <PropertyGridControl:CustomPropertyGrid x:Name="PropertyGrid" Grid.Column="1" />
  </Grid>
</Window>
