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

用到了控制項基類 UCControlBase，如果你還不瞭解UCControlBase，請移步 （一）c#Winform自定義控制項-基類控制項 查看

開始

添加一個用戶控制項，命名UCPanelTitle，繼承自UCControlBase

2個屬性　　

 1 [Description("邊框顏色"), Category("自定義")]
 2         public Color BorderColor
 3         {
 4             get { return this.RectColor; }
 5             set
 6             {
 7                 this.RectColor = value;
 8                 this.lblTitle.BackColor = value;
 9             }
10         }
11 
12         [Description("面板標題"), Category("自定義")]
13         public string Title
14         {
15             get { return lblTitle.Text; }
16             set { lblTitle.Text = value; }
17         }
