作为Winfrom开发者来说，我们很多时候会用到tabcontrol来实现和网页标签页相关的效果。同时微软自带的控件样式不符合我们的需求，我们该如何去实现更加美观且可以自定义的组合控件呢？带着这个问题进入我们今天的主题，组合控件tabcontrol实现。

我们用的是界面库为DSkin.dll，简单介绍下，DSkin是干什么的。界面库设计工具DSKin是DSkin界面库官网(www.dskin.cn)开发的Winfrom DirectUI界面库。Dskin可以动态Alpha混合，支持窗体和控件的透明度混合效果，以及多个控件叠加的效果，支持窗体设置透明色和透明图片直接呈现出来，制作异形窗体简单快速，以此同时，Dskin内置了许多个虚拟控件，绘制高效，无句柄，资源占用极低，控件可以相互嵌套和组合。相对于微软的原生Winform控件库而言，用Dskin开发的界面即使设置大张的背景图及控件比较多的时候不会出现闪烁。

现在正式切入我们今天的主题，我们先看下界面效果图，如图1所示界面显示了两种效果，分别是正常的标签页和激活的标签页。该界面效果可以通过CreateTempItemCount来创建效果效果，然后通过扩展的属性来调整样式。扩展属性如图2所示，这些属性是我们创建的属性，可以对属性进行修改或新增从而符合我们的需求。

图1 效果展示图

图2 控件扩展属性说明

我们组合控件是继承于DSkin.Controls.DSkinUserControl，控件主要由DSkinTabBar、DSkinTabControl组合实现。界面设计效果如图3所示，除了上述的主要控件之外，我们还添加了DSkinScrollBar(滚动条)、RichTextBox(富文本编辑框，用于计算文字所占宽度)、ContextMenuStrip(右键菜单栏)、ToolTip(提示框，用于属性滑过Item时显示对应的文本信息)。

图3 控件组合界面展示

由于我们的继承对象为UserControl，为此我们的组合控件除了具有了UserControl本身拥有的属性，我们还可以自己扩展属性。比如上述讲到的CreateTempItemCount，那如何创建呢？我们可以定义一个Public属性方法，我们可以设置该属性的默认值、指定属性或事件的功能说明，对应的代码关键词分别为DefaultValue、Description。实例代码如下：

        private int _CreateTempItemCount = 0;[DefaultValue(0)][Description("用于测试查看效果，实际使用请将其移除，设置为0清空")]public int CreateTempItemCount{get { return _CreateTempItemCount; }set{_CreateTempItemCount = value;this.dSkinTabBar.Items.Clear();this.dSkinTabControl.TabPages.Clear();for (int i = 0; i < _CreateTempItemCount; i++){TempCreate(i.ToString(), "测试样式" + i);}}}

扩展属性也创建完了，接下来就是创建标签页及页面绑定关系，由于我们使用的是TabControl，其本身就具有标签页的功能，我们为了让DSkinTabBar来替代标签功能，我们需要对TabControl的"ItemSize"属性设置为"0,1",同时将DSkinTabBar与DSkinTabControl绑定起来，则属性TabControl与我们创建的DSkinTabControl关联，这样即可相互影响。

我们的控件要求功能既能加载Control同时加载Form，因此我们需要针对两种不同的情况创建不同的方法。我们定义了两个属性dicControl和dicForm，用于右键菜单栏使用以及释放资源使用。

        #region 定义/// <summary>/// 用于关闭释放资源Control/// </summary>Dictionary<string, Control> dicControl = new Dictionary<string, Control>();/// <summary>/// 用于关闭释放资源Form/// </summary>Dictionary<string, Form> dicForm = new Dictionary<string, Form>();#endregion

我们标签页的宽度除了可以自定义设置，同时还可以根据传入的文本内自动计算所需要的宽度。这次将采用到RichTextBox控件来辅助实现，具体实现代码如下：

        #region 计算Item的宽度 /// <summary>/// 计算显示框高度和宽度，英文字体和中文以及标点、数字的宽度各不相同，需计算/// </summary>/// <param name="mess">文本</param>/// <param name="width">宽度</param>private int CalcItemWidth(string mess, int width){int Linewidth; //显示对话内容容器的宽度和高度//临时建立一个容器装入内容RichTextBox canv_Rich = new RichTextBox();//先取全部Rtf的值canv_Rich.Rtf = mess;//再按照Txt判断文字//判断中文MatchCollection zh = Regex.Matches(canv_Rich.Text, @"[\u4e00-\u9fa5]", RegexOptions.IgnoreCase | RegexOptions.Singleline);//判断中文标点MatchCollection zhdot = Regex.Matches(canv_Rich.Text, @"[，。；？~！：‘“”’【】（）]", RegexOptions.IgnoreCase | RegexOptions.Singleline);//判断数字MatchCollection en = Regex.Matches(canv_Rich.Text, @"[1234567890]", RegexOptions.IgnoreCase | RegexOptions.Singleline);//其余为英文，并计算总宽度Linewidth = (zh.Count + zhdot.Count) * 13 + en.Count * 8 + (canv_Rich.Text.Length - zh.Count - zhdot.Count - en.Count) * 7;//接收数据内容中是否包含图像int havePic = 0;havePic = Regex.Matches(canv_Rich.Rtf, "Paint.Picture").Count;//加上图像宽度Linewidth += havePic * 33;//判断极值//if (Linewidth > (12 * 13)) { Linewidth = 12 * 13; }if (Linewidth < width) { Linewidth = width; }return Linewidth;}#endregion

由于篇幅的原因，下方直接贴出代码，代码中有相对的说明，应该可以看到懂。

我们创建好控件生成之后，直接拖拽到对应的页面就可以。委托事件调用方法为：

  this.tabControlYd1.ClickEvent += tabControlYd1_ClickEvent;this.tabControlYd1.ChangTageKey += tabControlYd1_ChangTageKey;
