WPF中的控件模板(ControlTemplate)

最好的模板示例：我们知道每个控件都有自己默认的模板，这是MS编写的，如果我们能够得到这些模板的XAML代码，那么它将是学习模板的最好的示例，
要想获得某个控件ctrl的默认模板，请调用以下方法：

 

 

private string GetTemplateXamlCode(Control ctrl) { FrameworkTemplate template = ctrl.Template; string xaml = ""; if (template != null) { XmlWriterSettings settings = new XmlWriterSettings(); settings.Indent = true; settings.IndentChars = new string(' ', 4); settings.NewLineOnAttributes = true; StringBuilder strbuild = new StringBuilder(); XmlWriter xmlwrite = XmlWriter.Create(strbuild, settings); try { System.Windows.Markup.XamlWriter.Save(template, xmlwrite); xaml = strbuild.ToString(); } catch (Exception exc) { xaml = exc.Message; } } else { xaml = "no template"; } return xaml; }
