问题描述
我要复制一个复杂的数据绑定的UIElement ，但保持绑定，布局和显示的信息从原来的UIElement。
I wish to copy a complex data-bound UIElement but keep the Binding, Layout and Rendering information from the original UIElement.
创建一个新的的UIElement 似乎效率不高，因为我会做另一个完整的绑定/测量/整理/渲染过程
Creating a new UIElement seems inefficient since I would have to do another complete Binding/Measure/Arrange/Render pass.
到目前为止，我得到的最接近是创建一个新的 DrawingVisual ，打开它的渲染和使用源的UIElement DrawingGroup DrawDrawing。
The closest I've got so far is to create a new DrawingVisual, open it for rendering, and DrawDrawing using the source UIElement DrawingGroup.
DrawingVisual dv = new DrawingVisual();
DrawingGroup dg = VisualTreeHelper.GetDrawing(SourceElement);
using (DrawingContext dc = dv.RenderOpen())
{
Drawing d = dg.Children[0];
dc.DrawDrawing(d);
}
return dv;
这是一个好方法，将其用于复杂的UI元素内边框工作（如大量的面板，定制控制等等等等）？
Is this a good approach and will it work for complex UIElements (e.g. lots of Panels within Borders, custom Controls etc etc)?
要给你一个背景下，我想提出一个 DocumentPaginator 这是运作良好，但提前inefficeintly由于相同的UI元素的娱乐。
To give you a context, I am making a DocumentPaginator which is working well, but inefficeintly due to the recreation of identical UIElements.
谢谢，
皮特
