C# 向窗体添加新的PropertyChanged事件
我补充说C# 向窗体添加新的PropertyChanged事件,c#,winforms,events,enums,inotifypropertychanged,C#,Winforms,Events,Enums,Inotifypropertychanged,我补充说 public partial class FrmEditSiteParticulars : Form, INotifyPropertyChanged { public enum EntryTypes { Undefined, Site, Particular } private EntryTypes _EntryType; private EntryTypes EntryTyp
public partial class FrmEditSiteParticulars : Form, INotifyPropertyChanged
{
public enum EntryTypes
{
Undefined,
Site,
Particular
}
private EntryTypes _EntryType;
private EntryTypes EntryType {
get{return _EntryType;}
set
{
if (value != _EntryType)
{
_EntryType = value;
OnPropertyChanged("EntryType");
}
}
}
public event PropertyChangedEventHandler EntryTypeChanged;
protected void OnPropertyChanged(string propertyName)
{
PropertyChangedEventHandler handler = EntryTypeChanged;
if (handler != null)
handler(this, new PropertyChangedEventArgs(propertyName));
}
.
.
.
public event PropertyChangedEventHandler PropertyChanged;

内部初始化组件方法
现在当我打开设计器时
我单击了“忽略并继续”
,效果很好
现在,当我再次关闭并打开解决方案时,我放在InitializeComponent
中的eventHandler代码丢失了
有什么问题吗?看看这个:
this.EntryTypeChanged += new
System.ComponentModel.PropertyChangedEventHandler(this.EntryType_Changed);
//
///设计器支持所需的方法-不修改
///此方法的内容与代码编辑器一起使用。
///
私有void InitializeComponent()
答案就在这里。将代码放入构造函数中,在InitializeComponent()下面代码>您的观察和解决方案的方法非常出色:)
/// <summary>
/// Required method for Designer support - do not modify
/// the contents of this method with the code editor.
/// </summary>
private void InitializeComponent()
