Changes in my userControl are erased when I rebuild in Visual Studio (designer view)

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;
        }
    }
}

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

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

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

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

An开发者_JAVA技巧y ideas why?

Thank you for your time.

Perhaps your changes are not persisted by the designer.

Did you try using DesignerSerializationVisibilityAttribute?

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();
     }
}
