准备工作
其实我也不知道这个应该叫什么名字，暂且叫有后退的窗体吧，这个窗体继承子基类窗体FrmBase，如果你对FrmBase还不了解，请移步 （十七）c#Winform自定义控件-基类窗体 查看
开始
添加一个Form，命名FrmBack，继承自FrmBase
属性
1 private string _frmTitle = "自定义窗体";
2 /// <summary>
3 /// 窗体标题
4 /// </summary>
5 [Description("窗体标题"), Category("自定义")]
6 public string FrmTitle
7 {
8 get { return _frmTitle; }
9 set
10 {
11 _frmTitle = value;
12 btnBack1.BtnText = value;
13 }
14 }
15 [Description("帮助按钮点击事件"), Category("自定义")]
16 public event EventHandler BtnHelpClick;
一点小事件
1 private void btnBack1_btnClick(object sender, EventArgs e)
2 {
3 this.Close();
4 }
5
6 private void label1_MouseDown(object sender, MouseEventArgs e)
7 {
8 if (BtnHelpClick != null)
9 BtnHelpClick(sender, e);
10 }
