前提

入行已經7,8年了，一直想做一套漂亮點的自定義控制項，於是就有了本系列文章。

準備工作

其實我也不知道這個應該叫什麼名字，暫且叫有後退的窗體吧，這個窗體繼承子基類窗體FrmBase，如果你對FrmBase還不瞭解，請移步（十七）c#Winform自定義控制項-基類窗體查看

開始

添加一個Form，命名FrmBack，繼承自FrmBase

屬性

 1  private string _frmTitle = "自定義窗體";
 2         /// <summary>
 3         /// 窗體標題
 4         /// </summary>
 5         [Description("窗體標題"), Category("自定義")]
 6         public string FrmTitle
 7         {
 8             get { return _frmTitle; }
 9             set
10             {
11                 _frmTitle = value;
12                 btnBack1.BtnText = value;
13             }
14         }
15         [Description("幫助按鈕點擊事件"), Category("自定義")]
16         public event EventHandler BtnHelpClick;

一點小事件

 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         }
