隐藏可扩展属性（例如“…”）的省略号（...）按钮属性网格中的字体属性按钮 [英] Hide ellipsis (…) button of expandable property like "…" button of font property in the property grid

问题描述

我在自定义控件中添加了一个新属性，作为可扩展属性，例如属性网格中的字体属性。从Windows窗体应用程序项目中的自定义控件使用后，我在属性网格中看到一个省略号（...）按钮，如font属性的 ...按钮。 （有关更多信息，请参见下图。）

现在，我想隐藏新扩展属性的省略号（...）按钮。

可扩展的属性代码为：

  [DisplayName（ Floors Information）] 
 [ Description（ Floors Informationnnnnnnnnnnnnnnn）] 
 [DefaultProperty（ TitleText）] 
 [DesignerCategory（ Component）] 
公共类FloorsInformation：DockContainerItem 
 {
私人的SameFloorsInformation类似的FloorsInformation =新的相似的FloorsInformation（）; 
 
 public FloorsInformation（）
 {
 
} 
 
 [Category（ Data）] 
 [DisplayName（相似楼层面板）]

 [DesignerSerializationVisibility（DesignerSerializationVisibility.Content）] 
 [Editor（typeof（ItemsCollectionEditor），typeof（UITypeEditor））] 
 // [TypeConverter（typeof（ExpandableObjectConverter））] 
 // [TypeConverter（typeof（SimilarFloorsInformationTypeConverter））] 
 public SameFloorsInformation SameFloorsInfo 
 {
 get 
 {
 return sameFloorsInformation; 
} 
} 
} 
 
 [DisplayName（相似楼层信息）]

 // [TypeConverter（typeof（ExpandableObjectConverter））] $ b b $ b public class SameFloorsInformation：ExpandablePanel

私人DockStyle基座= DockStyle.Right; 
私人eTitleButtonAlignment expandButtonAlignment = eTitleButtonAlignment.Left; 
私人布尔扩展=假； 
 private bool markupUsesStyleAlignment = true; 
 private Size size = new Size（30，177）;

 {
 
} 
} 
 
 public class SimilarFloorsInformationTypeConverter：ExpandableObjectConverter // TypeConverter 
 {
公共重写bool CanConvertTo（ITypeDescriptorContext上下文，类型destinationType）
 {
 if（destinationType == typeof（SimilarFloorsInformation））
 {

} 
返回base.CanConvertTo（context，destinationType）; 
} 
 
公共重写对象ConvertTo（ITypeDescriptorContext上下文，CultureInfo文化，对象值，类型destinationType）
 {

 {

 return sameFloorsInformation.TitleText; 
} 
返回base.ConvertTo（context，culture，value，destinationType）; 
} 
 
公共重写bool CanConvertFrom（ITypeDescriptorContext context，type sourceType）
 {
 if（sourceType == typeof（string））
 {
返回true； 
} 
返回base.CanConvertFrom（context，sourceType）; 
} 
 
公共替代对象ConvertFrom（ITypeDescriptorContext上下文，CultureInfo文化，对象值）
 {
 if（值是字符串）
 {
 SimilarFloorsInformation similarFloorsInformation = new LikeFloorsInformation（）; 
 similarFloorsInformation.TitleText =（string）value; 
 return sameFloorsInformation; 
} 
返回base.ConvertFrom（上下文，文化，价值）; 
} 
} 
  

解决方案

I根据Nikolay Khil的回答解决了我的问题。对于我已应用于自定义控件的 SimilarFloorsInfo 属性的以下代码行（属性），显示了省略号（...）按钮：

  [Editor（typeof（ItemsCollectionEditor），typeof（UITypeEditor））] 
  

因此，必须删除或注释此行代码。现在，在属性网格中没有为我的属性显示省略号（...）按钮。

I've added a new property to my custom control as expandable property like font property in Property Grid. After using from my custom control in a Windows Forms Application project, I see an ellipsis (…) button like "…" button of font property in Property Grid. (For more information, please see the following picture.)

Now, I want to hide the ellipsis (…) button for my new expandable property.

Expandable property codes are:

[DisplayName("Floors Information")]
[Description("Floors Informationnnnnnnnnnnnnnnn")]
[DefaultProperty("TitleText")]
[DesignerCategory("Component")]
public class FloorsInformation : DockContainerItem
{
    private SimilarFloorsInformation similarFloorsInformation = new SimilarFloorsInformation();

    public FloorsInformation()
    {

    }

    [Category("Data")]
    [DisplayName("Similar Floors Panel")]
    [Description("Similar Floors Panellllllllllllllllllll")]
    [DesignerSerializationVisibility(DesignerSerializationVisibility.Content)]
    [Editor(typeof(ItemsCollectionEditor), typeof(UITypeEditor))]
    //[TypeConverter(typeof(ExpandableObjectConverter))]
    //[TypeConverter(typeof(SimilarFloorsInformationTypeConverter))]
    public SimilarFloorsInformation SimilarFloorsInfo
    {
        get
        {
            return similarFloorsInformation;
        }
    }
}

[DisplayName("Similar Floors Information")]
[Description("Similar Floors Informationnnnnnnnnnnnnnnn")]
[DefaultProperty("Text")]
[DesignerCategory("Component")]
[TypeConverter(typeof(SimilarFloorsInformationTypeConverter))]
//[TypeConverter(typeof(ExpandableObjectConverter))]
public class SimilarFloorsInformation : ExpandablePanel
{
    private Color canvasColor = SystemColors.Control;
    private eCollapseDirection collapseDirection = eCollapseDirection.LeftToRight;
    private eDotNetBarStyle colorSchemeStyle = eDotNetBarStyle.StyleManagerControlled;
    private DockStyle dock = DockStyle.Right;
    private eTitleButtonAlignment expandButtonAlignment = eTitleButtonAlignment.Left;
    private bool expanded = false;
    private bool markupUsesStyleAlignment = true;
    private Size size = new Size(30, 177);

    public SimilarFloorsInformation()
    {

    }
}

public class SimilarFloorsInformationTypeConverter : ExpandableObjectConverter//TypeConverter
{
    public override bool CanConvertTo(ITypeDescriptorContext context, Type destinationType)
    {
        if (destinationType == typeof(SimilarFloorsInformation))
        {
            return true;
        }
        return base.CanConvertTo(context, destinationType);
    }

    public override object ConvertTo(ITypeDescriptorContext context, CultureInfo culture, object value, Type destinationType)
    {
        if (destinationType == typeof(String) && value is SimilarFloorsInformation)
        {
            SimilarFloorsInformation similarFloorsInformation = (SimilarFloorsInformation)value;
            return similarFloorsInformation.TitleText;
        }
        return base.ConvertTo(context, culture, value, destinationType);
    }

    public override bool CanConvertFrom(ITypeDescriptorContext context, Type sourceType)
    {
        if (sourceType == typeof(string))
        {
            return true;
        }
        return base.CanConvertFrom(context, sourceType);
    }

    public override object ConvertFrom(ITypeDescriptorContext context, CultureInfo culture, object value)
    {
        if (value is string)
        {
            SimilarFloorsInformation similarFloorsInformation = new SimilarFloorsInformation();
            similarFloorsInformation.TitleText = (string)value;
            return similarFloorsInformation;
        }
        return base.ConvertFrom(context, culture, value);
    }
}

解决方案

I solved my problem according to Nikolay Khil answer. Ellipsis (...) button is shown for following line of code (Attribute) that I've applied to the "SimilarFloorsInfo" property of my custom control:

[Editor(typeof(ItemsCollectionEditor), typeof(UITypeEditor))]

So, this line of code must be deleted or commented. Now, Ellipsis (...) button not shown for my property in the property grid.
