C# Dev PropertyGrid

使用propertyGridControl控件，在Data工具栏下，核心是利用反射技术

1、定义工具类

添加引用：using System.ComponentModel;

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Drawing;
using System.ComponentModel;
using System.Windows.Forms;
using DevExpress.XtraEditors;

namespace XtraVerticalGrid
{
    [DefaultPropertyAttribute("SaveOnClose")]
    public class AppSettings1
    {
        private bool saveOnClose = true;
        private string greetingText = "欢迎使用应用程序！";
        private int maxRepeatRate = 10;
        private int itemsInMRU = 4;
        private bool settingsChanged = false;
        private string appVersion = "1.0";
        private string DefaultFileName = "Name";

        private Size windowSize = new Size(100, 100);
        private Font windowFont = new Font("宋体", 9, FontStyle.Regular);
        private Color toolbarColor = SystemColors.Control;
        [CategoryAttribute("文档设置"),
        DefaultValueAttribute(true)]
        public bool SaveOnClose
        {
            get { return saveOnClose; }
            set { saveOnClose = value; }
        }
        [CategoryAttribute("文档设置")]
        public Size WindowSize
        {
            get { return windowSize; }
            set { windowSize = value; }
        }
        [CategoryAttribute("文档设置")]
        public Font WindowFont
        {
            get { return windowFont; }
            set { windowFont = value; }
        }
        [CategoryAttribute("全局设置")]
        public Color ToolbarColor
        {
            get { return toolbarColor; }
            set { toolbarColor = value; }
        }
        [CategoryAttribute("全局设置"),
        ReadOnlyAttribute(true),
        DefaultValueAttribute("欢迎使用应用程序！")]
        public string GreetingText
        {
            get { return greetingText; }
            set { greetingText = value; }
        }
        [CategoryAttribute("全局设置"),
        DefaultValueAttribute(4)]
        public int ItemsInMRUList
        {
            get { return itemsInMRU; }
            set { itemsInMRU = value; }
        }
        [DescriptionAttribute("以毫秒表示的文本重复率。"),
        CategoryAttribute("全局设置"),
        DefaultValueAttribute(10)]
        public int MaxRepeatRate
        {
            get { return maxRepeatRate; }
            set { maxRepeatRate = value; }
        }
        [BrowsableAttribute(false),
        DefaultValueAttribute(false)]
        public bool SettingsChanged
        {
            get { return settingsChanged; }
            set { settingsChanged = value; }
        }
        [CategoryAttribute("版本"),
        DefaultValueAttribute("1.0"),
        ReadOnlyAttribute(true)]
        public string AppVersion
        {
            get { return appVersion; }
            set { appVersion = value; }
        }
        [CategoryAttribute("拼写检查选项"),
        DefaultValueAttribute("DefaultFileName")]
        public string SpellingOptions
        {
            get { return this.DefaultFileName; }
            set { this.DefaultFileName = value; }
        }
    }
}

2、直接创建此类的对象，将窗体绑定上来

 AppSettings1 appset = new AppSettings1();
            this.propertyGridControl1.SelectedObject = appset;

例子2：创建下拉框

方法：利用TypeConverter方法，将自定义的配置下拉项，转换

1、配置主界面：

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.ComponentModel;

namespace XtraVerticalGrid
{  
    public class AppSettings
    {
        private string extendDirection = "横向";
        private string extendConfig = "横向";
        private string dataGroup = "不分组";
        private string dataCollection = "合计";
        private string blankLine = "不补充";

        [CategoryAttribute("扩展方向"),
        DefaultValueAttribute("横向"),
         TypeConverter(typeof(ExtendDirection))]
        public string 扩展方向
        {
            get { return extendDirection; }
            set { extendDirection = value; }
        }

        [CategoryAttribute("可扩展性"),
         DefaultValueAttribute("横向"),
         TypeConverter(typeof(ExtendConfig))]
        public string 可扩展性
        {
            get { return extendConfig; }
            set { extendConfig = value; }
        }

        [CategoryAttribute("数据分组设置"),
         DefaultValueAttribute("不分组"),
         TypeConverter(typeof(DataGroup))]
        public string 分组
        {
            get { return dataGroup; }
            set { dataGroup = value; }
        }

        [CategoryAttribute("数据分组设置"),
         DefaultValueAttribute("合计"),
         TypeConverter(typeof(DataCollection))]
        public string 汇总
        {
            get { return dataCollection; }
            set { dataCollection = value; }
        }

        [CategoryAttribute("补充空白行"),
        DefaultValueAttribute("不补充"),
        TypeConverter(typeof(BlankLine))]
        public string 补充空白行
        {
            get { return blankLine; }
            set { blankLine = value; }
        }
 
    }
}

2、配置子选项内容：

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.ComponentModel;

namespace XtraVerticalGrid
{
    /// <summary>
    /// 扩展方向配置
    /// </summary>
    public class ExtendDirection : StringConverter
    {
        public override bool GetStandardValuesSupported(ITypeDescriptorContext context)
        {
            return true;
        }
        public override StandardValuesCollection GetStandardValues(ITypeDescriptorContext context)
        {
            return new StandardValuesCollection(new string[] { "横向", "纵向"});
        } 
    }

    /// <summary>
    /// 可扩展性配置
    /// </summary>
    public class ExtendConfig : StringConverter
    {
        public override bool GetStandardValuesSupported(ITypeDescriptorContext context)
        {
            return true;
        }
        public override StandardValuesCollection GetStandardValues(ITypeDescriptorContext context)
        {
            return new StandardValuesCollection(new string[] { "横向", "纵向" });
        }
    }

    /// <summary>
    /// 数据分组设置
    /// </summary>
    public class DataGroup : StringConverter
    {
        public override bool GetStandardValuesSupported(ITypeDescriptorContext context)
        {
            return true;
        }
        public override StandardValuesCollection GetStandardValues(ITypeDescriptorContext context)
        {
            return new StandardValuesCollection(new string[] { "不分组", "相同分组" });
        }
    }

    /// <summary>
    /// 数据汇总设置
    /// </summary>
    public class DataCollection : StringConverter
    {
        public override bool GetStandardValuesSupported(ITypeDescriptorContext context)
        {
            return true;
        }
        public override StandardValuesCollection GetStandardValues(ITypeDescriptorContext context)
        {
            return new StandardValuesCollection(new string[] { "合计", "平均","最大","最小","记录数" });
        }
    }


    /// <summary>
    /// 补充空白行
    /// </summary>
    public class BlankLine : StringConverter
    {
        public override bool GetStandardValuesSupported(ITypeDescriptorContext context)
        {
            return true;
        }
        public override StandardValuesCollection GetStandardValues(ITypeDescriptorContext context)
        {
            return new StandardValuesCollection(new string[] { "不补充", "补满页","固定行" });
        }
    } 
}

例子3：配置子项的列表

1、配置主界面：

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Drawing;
using System.ComponentModel;
using System.Windows.Forms;
using DevExpress.XtraEditors;

namespace XtraVerticalGrid
{
    [DefaultPropertyAttribute("SaveOnClose")]
    public class AppSettings1
    {
        private bool saveOnClose = true;
        private string greetingText = "欢迎使用应用程序！";
        private int maxRepeatRate = 10;
        private int itemsInMRU = 4;
        private bool settingsChanged = false;
        private string appVersion = "1.0";
        <span style="color:#ff0000;">private SpellingOptions DefaultFileName = new SpellingOptions();</span>

        private Size windowSize = new Size(100, 100);
        private Font windowFont = new Font("宋体", 9, FontStyle.Regular);
        private Color toolbarColor = SystemColors.Control;
        [CategoryAttribute("文档设置"),
        DefaultValueAttribute(true)]
        public bool SaveOnClose
        {
            get { return saveOnClose; }
            set { saveOnClose = value; }
        }
        [CategoryAttribute("文档设置")]
        public Size WindowSize
        {
            get { return windowSize; }
            set { windowSize = value; }
        }
        [CategoryAttribute("文档设置")]
        public Font WindowFont
        {
            get { return windowFont; }
            set { windowFont = value; }
        }
        [CategoryAttribute("全局设置")]
        public Color ToolbarColor
        {
            get { return toolbarColor; }
            set { toolbarColor = value; }
        }
        [CategoryAttribute("全局设置"),
        ReadOnlyAttribute(true),
        DefaultValueAttribute("欢迎使用应用程序！")]
        public string GreetingText
        {
            get { return greetingText; }
            set { greetingText = value; }
        }
        [CategoryAttribute("全局设置"),
        DefaultValueAttribute(4)]
        public int ItemsInMRUList
        {
            get { return itemsInMRU; }
            set { itemsInMRU = value; }
        }
        [DescriptionAttribute("以毫秒表示的文本重复率。"),
        CategoryAttribute("全局设置"),
        DefaultValueAttribute(10)]
        public int MaxRepeatRate
        {
            get { return maxRepeatRate; }
            set { maxRepeatRate = value; }
        }
        [BrowsableAttribute(false),
        DefaultValueAttribute(false)]
        public bool SettingsChanged
        {
            get { return settingsChanged; }
            set { settingsChanged = value; }
        }
        [CategoryAttribute("版本"),
        DefaultValueAttribute("1.0"),
        ReadOnlyAttribute(true)]
        public string AppVersion
        {
            get { return appVersion; }
            set { appVersion = value; }
        }
        [CategoryAttribute("拼写检查选项"),
        TypeConverter(typeof(SpellingOptionsConverter)),
        DefaultValueAttribute("DefaultFileName")]
        public SpellingOptions SpellingOptions
        {
            get { return this.DefaultFileName; }
            set { this.DefaultFileName = value; }
        }
    }
}

2、创建主界面下拉的子类：

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Drawing;
using System.ComponentModel;
using System.Windows.Forms;
using DevExpress.XtraEditors;

namespace XtraVerticalGrid
{
    [DescriptionAttribute("展开以查看应用程序的拼写选项。")]
    public class SpellingOptions
    {
        private bool spellCheckWhileTyping = true;
        private bool spellCheckCAPS = false;
        private bool suggestCorrections = true;
        [DefaultValueAttribute(true)]
        public bool SpellCheckWhileTyping
        {
            get { return spellCheckWhileTyping; }
            set { spellCheckWhileTyping = value; }
        }
        [DefaultValueAttribute(false)]
        public bool SpellCheckCAPS
        {
            get { return spellCheckCAPS; }
            set { spellCheckCAPS = value; }
        }
        [DefaultValueAttribute(true)]
        public bool SuggestCorrections
        {
            get { return suggestCorrections; }
            set { suggestCorrections = value; }
        }
    }
}

3、创建类，判断类型

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.ComponentModel;
using System.Globalization;

namespace XtraVerticalGrid
{
    public class SpellingOptionsConverter : ExpandableObjectConverter
    {
        public override bool CanConvertTo(ITypeDescriptorContext context,
                                   System.Type destinationType)
        {
            if (destinationType == typeof(SpellingOptions))
                return true;
            return base.CanConvertTo(context, destinationType);
        }
        public override object ConvertTo(ITypeDescriptorContext context, CultureInfo culture,
                                         object value, System.Type destinationType)
        {
            if (destinationType == typeof(System.String) &&
                 value is SpellingOptions)
            {
                SpellingOptions so = (SpellingOptions)value;
                return "在键入时检查:" + so.SpellCheckWhileTyping +
                       "，检查大小写: " + so.SpellCheckCAPS +
                       "，建议更正: " + so.SuggestCorrections;
            }
            return base.ConvertTo(context, culture, value, destinationType);
        }

        public override object ConvertFrom(ITypeDescriptorContext context, CultureInfo culture, object value)
        {
            if (value is string)
            {
                try
                {
                    string s = (string)value;
                    int colon = s.IndexOf(':');
                    int comma = s.IndexOf(',');
                    if (colon != -1 && comma != -1)
                    {
                        string checkWhileTyping = s.Substring(colon + 1, (comma - colon - 1));
                        colon = s.IndexOf(':', comma + 1);
                        comma = s.IndexOf(',', comma + 1);
                        string checkCaps = s.Substring(colon + 1, (comma - colon - 1));
                        colon = s.IndexOf(':', comma + 1);
                        string suggCorr = s.Substring(colon + 1);
                        SpellingOptions so = new SpellingOptions();
                        so.SpellCheckWhileTyping = Boolean.Parse(checkWhileTyping);
                        so.SpellCheckCAPS = Boolean.Parse(checkCaps);
                        so.SuggestCorrections = Boolean.Parse(suggCorr);
                        return so;
                    }
                }
                catch
                {
                    throw new ArgumentException(
                        "无法将“" + (string)value +
                                           "”转换为 SpellingOptions 类型");
                }
            }
            return base.ConvertFrom(context, culture, value);
        } 
    }
}
