用处及效果

准备工作

没什么可准备的,直接往下看吧

开始

添加一个类UCPanelQuote继承 Panel

添加2个属性

 1 /// <summary>   2         /// The border color   3         /// </summary>   4         private Color borderColor = LineColors.Light;   5   6         /// <summary>   7         /// Gets or sets the color of the border.   8         /// </summary>   9         /// <value>The color of the border.</value>  10         [Description("边框颜色"), Category("自定义")]  11         public Color BorderColor  12         {  13             get { return borderColor; }  14             set  15             {  16                 borderColor = value;  17                 this.Invalidate();  18             }  19         }  20  21         /// <summary>  22         /// The left color  23         /// </summary>  24         private Color leftColor = StatusColors.Danger;  25  26         /// <summary>  27         /// Gets or sets the color of the left.  28         /// </summary>  29         /// <value>The color of the left.</value>  30         [Description("左侧颜色"), Category("自定义")]  31         public Color LeftColor  32         {  33             get { return leftColor; }  34             set  35             {  36                 leftColor = value;  37                 this.Invalidate();  38             }  39         }

为了画边框和左边的颜色,设置一下Padding

1    public UCPanelQuote()  2             : base()  3         {  4             Padding = new Padding(5, 1, 1, 1);  5         }

重绘

 1 protected override void OnPaint(PaintEventArgs e)   2         {   3             base.OnPaint(e);   4             e.Graphics.SetGDIHigh();   5   6             e.Graphics.DrawLines(new Pen(borderColor), new Point[]   7             {   8                 new Point(e.ClipRectangle.Left,e.ClipRectangle.Top),   9                 new Point(e.ClipRectangle.Right-1,e.ClipRectangle.Top),  10                 new Point(e.ClipRectangle.Right-1,e.ClipRectangle.Bottom-1),  11                 new Point(e.ClipRectangle.Left,e.ClipRectangle.Bottom-1),  12                 new Point(e.ClipRectangle.Left,e.ClipRectangle.Top)  13             });  14  15             e.Graphics.FillRectangle(new SolidBrush(leftColor), new Rectangle(0, 0, 5, this.Height));  16         }
