使用FrameworkElementFactory FrameworkElementFactory用于以编程的方式创建模板,虽然文档中说不推荐,但WPF中常常使用这个类,例如DisplayMemberTemplateSelector FrameworkElementFactory text = new FrameworkElementFactory(typeof(TextBlock)); Binding binding = new 参考 FrameworkElementFactory XamlWriter XamlWriter and Bindings Serialization TypeConverter TypeDescriptor

等方法,如下代码 static ContentPresenter() { DataTemplate template; FrameworkElementFactory CreateAccessTextFactory() { FrameworkElementFactory text = new FrameworkElementFactory (typeof(AccessText)); return text; } 在 CreateAccessTextFactory 创建的 FrameworkElementFactory 对象的构造函数代码如下,在构造函数将会给 FrameworkElementFactory.Type 属性赋值 public FrameworkElementFactory(Type type , string name) { Type = type; Name = name; } 然而 FrameworkElementFactory.Type
WireDiameter">线径</param> /// <param name="Opacity">透明度</param> /// <returns></returns> FrameworkElementFactory GetFactory(Brush InnerColor, Brush OuterColor, double WireDiameter) { FrameworkElementFactory Element = new FrameworkElementFactory(typeof(Ellipse)); //绘制椭圆形元素 Element.SetValue(Ellipse.FillProperty
WireDiameter">线径</param> /// <param name="Opacity">透明度</param> /// <returns></returns> FrameworkElementFactory GetFactory(Brush InnerColor, Brush OuterColor, double WireDiameter) { FrameworkElementFactory Element = new FrameworkElementFactory(typeof(Ellipse)); //绘制椭圆形元素 Element.SetValue(Ellipse.FillProperty
比如在代码中创建 DataTemplate,主要会使用到 FrameworkElementFactory 类型。
简而言之,这个方法的流程有三个分支:1)如果一个FrameworkTemplate的_templateRoot字段(FrameworkElementFactory类型)不为空,则调用其_templateRoot.InstantiateTree
dependencyObject.GetValue(NameScopeProperty)); } 同样实现了此接口的还有 TemplateNameScope,此 NameScope 会被 FrameworkTemplate / FrameworkElementFactory
frameworkTemplate, ref bool isSealed, FrameworkElementFactory
