如何去掉TabControl控件默认添加的TabPage2010-12-24 博客园 周雪峰把TabControl添加到设计器的时候,默认会添加两个TabPage,当继承 TabControl自定义控件的时候,这两个默认的TabPage常常会制造一些麻烦,今 天我来介绍一种方法来去掉这两个默认的TabPage:实际上思路比较简单,主要是通过ToolboxItem特性提供自定义的 ToolboxItem类来修改工具箱中的控件的初始化工程,只需要继承ToolboxItem类 ,重写CreateComponentsCore方法就可以实现了:[ToolboxItem(typeof(DemoToolboxItem))] public class MyTabControl : TabControl { }
[Serializable] //ToolboxItem必须是可序列化的 class DemoToolboxItem : ToolboxItem { // The add components dialog in VS looks for a public // ctor that takes a type. public DemoToolboxItem(Type toolType) : base(toolType) { } // And you must provide this special constructor for serialization. // If you add additional data to MyToolboxItem that you // want to serialize, you may override Deserialize and // Serialize methods to add that data. DemoToolboxItem(SerializationInfo info, StreamingContext context) { Deserialize(info, context); } // This implementation sets the new control"s Text and // AutoSize properties. protected override IComponent[] CreateComponentsCore( IDesignerHost host, IDictionary defaultValues) { IComponent[] comps = base.CreateComponentsCore(host, defaultValues);
