帮助，我无法将属性添加到设计器PropertyGrid中 [英] Help, i can't get my properties into the designer PropertyGrid

问题描述

这有什么问题？属性LeftImage不会显示在PropertyGrid（WinForms .NET 3.5）中。

What is wrong with this? The property LeftImage doesn't show up in the PropertyGrid (WinForms .NET 3.5)

    private Image _LeftImage;

    /// <summary>
    /// Sets the small image appearing to the left of the trackbar
    /// </summary>

    [
    Description("The small image appearing to the left of the trackbar"),
    Category("Appearance"),
    EditorAttribute(typeof(System.Drawing.Design.ImageEditor), typeof(System.Drawing.Design.UITypeEditor)),
    DefaultValueAttribute(typeof(Image),"null"),
    Browsable(true), EditorBrowsable(EditorBrowsableState.Always)
    ]

    public Image LeftImage
    {
        private get { return _LeftImage; }
        set
        {
            if (value.Height != 16 || value.Width != 16)
            {
                _LeftImage = new Bitmap(value,new Size(16,16));
            }
            else _LeftImage = value;
            Invalidate();
        }
    }

我在哪里出错了？？？ IDE不会抱怨任何东西，并且可以正常编译，并且所有其他属性都可以正常显示。有什么想法吗？

Where do i go wrong??? The IDE doesn't complain about anything, and it compiles fine, and all the other properties show up alright. Any thoughts?

推荐答案

在LeftImage的get语句上删除私有访问器。将其更改为

Remove the private accessor on get statement of LeftImage. Change it to

get { return m_LeftImage; }
