当我在 Visual Studio(设计器视图)中重建时，我的 userControl 中的更改被删除 [英] Changes in my userControl are erased when I rebuild in Visual Studio (designer view)

问题描述

This is my navigationItem.cs user control:


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; }
        private string _linkText = String.Empty;
        [Browsable(true)]
        public string LinkText
        {
            get { return this._linkText; }
            set
            {
                this._linkText = value;
                RefreshDisplay();
            }
        }

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

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

            lblText.Text = Text;
        }
    }
}

我的目的是在另一个名为 NavigationBar 的用户控件中使用它.

My intention is to use this in another usercontrol called NavigationBar.

虽然我可以看到 NavigationItem.cs 类的 LinkText 属性，但当我从属性窗格更改它时，会弹出警告:

While I CAN see the LinkText attribute of the NavigationItem.cs class, when I change it from the properties pane, a warning pops up:

警告 1 您必须重建您的项目变更Uboldi.LeftNavigationbar 出现在任何开放的设计师.

Warning 1 You must rebuild your project for the changes to Uboldi.LeftNavigationbar to show up in any open designers.

公平，我重建，然后我刚刚输入的更改消失了！

Fair enough, I rebuild, and then the changes I just typed in are gone!

知道为什么吗?

感谢您抽出宝贵时间.

推荐答案

这是旧的，但没有答案.这是我发现有效的方法.希望这对其他人有所帮助.

This is old but doesn't have an answer. Here is what I found that works. Hopefully this helps someone else.

[Browsable(true)]
[DesignerSerializationVisibility(DesignerSerializationVisibility.Visible)]
[Description("Test text displayed in the link"), Category("Data")]
public string LinkText
{
     get { return this._linkText; }
     set
     {
         this._linkText = value;
         RefreshDisplay();
     }
}
