c# - Windows 窗体 PropertyView 不可见文本

Question

我在 C# 解决方案中有一个弹出窗口，其中有一个 PropertyView 控件...突然之间，属性字段报告了一个不可见的值，但是如果我单击该字段，则该值变得可见。如果我然后单击该字段，则该值再次隐藏...昨天一切都很好今天我从 16.9.0 更新到 Visual Studio 16.9.1...这可能是原因吗？同样在另一台计算机上的已部署解决方案上，这些字段的行为方式相同......但昨天在我的站上一切都很好，我至少一周内没有触摸这些弹出窗口......代码是在 c# 中开发的.Net 5 与 windows 窗体。

        private System.Windows.Forms.PropertyGrid plcPropertyGrid;

}

这是我的弹出式设计师课程。

public PlcParametersPopup(PlcSettings plcParameters, MainView main)
{
       InitializeComponent();

       PlcName = plcParameters.Name;

       Text = PlcName + " Parameters";

       plcPropertyGrid.SelectedObject = plcParameters;
       mainView = main;
}

这是弹出窗口的构造函数，如您所见，我将包含一系列属性字段的类传递给 SelectedObject 字段，如下所示。

namespace LiMA.Parameters
{
    public class PlcSettings
    {
        [Category("Basic Settings"), Description("Name of the PLC"), ReadOnly(true)]
        public string Name { get; set; }

        [Category("Addressing Settings"), Description("Ip address of the PLC"), ReadOnly(true)]
        public string IpAddr { get; set; }
