C# visual-studio designer propertyeditor

为什么某些控件属性显示在 Visual Studio 设计器中，而其他属性则不显示？

以我的 navigationItem 用户控件为例：

using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Drawing;
using System.Data;
using System.Linq;
using System.Text;
using System.Windows.Forms;
using Uboldi.Helpers;

namespace Uboldi
{
    public partial class NavigationItem : UserControl
    {
        public bool IsSelected { get; set; }
        public string Text { get; set; }

        public NavigationItem()
        {
            InitializeComponent();
            RefreshDisplay();
        }

        private void RefreshDisplay()
        {
            if (IsSelected)
                this.BackColor = CustomizationHelper.GetSecondaryColor();
            else
                this.BackColor = CustomizationHelper.GetPrimaryColor();            
        }
    }
}

在 Visual Studio 中，我可以看到 IsSelected 属性，但看不到 Text 属性。在此处输入图像描述

有什么原因吗？

Take my navigationItem usercontrol:

using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Drawing;
using System.Data;
using System.Linq;
using System.Text;
using System.Windows.Forms;
using Uboldi.Helpers;

namespace Uboldi
{
    public partial class NavigationItem : UserControl
    {
        public bool IsSelected { get; set; }
        public string Text { get; set; }

        public NavigationItem()
        {
            InitializeComponent();
            RefreshDisplay();
        }

        private void RefreshDisplay()
        {
            if (IsSelected)
                this.BackColor = CustomizationHelper.GetSecondaryColor();
            else
                this.BackColor = CustomizationHelper.GetPrimaryColor();            
        }
    }
}

In Visual Studio I can see the IsSelected property, but not the Text property.

Any reason why?

Text 属性继承自 UserControl。在隐藏的地方，用户控件无法以有意义的方式显示文本。您必须再次继承它并关闭所有使其隐藏的属性。像这样：

    [Browsable(true)]
    [EditorBrowsable(EditorBrowsableState.Always)]
    [DesignerSerializationVisibility(DesignerSerializationVisibility.Content)]
    [Bindable(true)]
    public override string Text {
        get { return base.Text; }
        set { base.Text = value; }
    }

The Text property is inherited from UserControl. Where it is hidden, a user control has no meaningful way of of showing text. You have to inherit it again and turn all the attributes off that make it hidden. Like this:

    [Browsable(true)]
    [EditorBrowsable(EditorBrowsableState.Always)]
    [DesignerSerializationVisibility(DesignerSerializationVisibility.Content)]
    [Bindable(true)]
    public override string Text {
        get { return base.Text; }
        set { base.Text = value; }
    }

您需要使用可浏览属性。

[Browsable(true)]
public bool Text { get; set; }

据猜测，IsSelected 属性被继承，并设置了此属性。我可能会离开，因为我认为编译器会警告您，如果是这种情况，您正在隐藏继承的属性。

You need to mark the properties you want visible in the design time properties list with a BrowsableAttribute.

[Browsable(true)]
public bool Text { get; set; }

At a guess, the IsSelected property was inherited, and had this attribute set. I'm probably off, because I think the compiler would warn you that you were shadowing an inherited property if this was the case.
