WPF绑定用户娱乐 [英] WPF Binding User Entertainment

问题描述

我已经遇到了一个情况我有一个ItemsControl生成一个数据收集pretty的复杂的可视化树，死的简单：

I have ran into a situation where I have an ItemsControl generate a pretty complex visual tree from a data collection, dead simple:

<ItemsControl ItemsSource="{Binding Items}"/>

小我的问题是，当出现初始绑定建设可能需​​要的时间显着时，将其（从1/2秒〜2秒，这取决于树的复杂性在任何地方），建筑本身。在此期间，用户界面​​线程完全不响应（挂起动画，点击量是未注册的，等等）。

The small problem I have is when the initial binding construction occurs it can take a "noticeable" amount of time when it is building itself (anywhere from 1/2 a second to 2 seconds depending on tree complexity). During this period the UI thread is completely unresponsive (animations hang, clicks are unregistered, etc).

虚拟化已经启用并正常工作，所以基本上所有我想要的是同时ItemContainerGenerator做它的事情。以播放动画的能力

Virtualization is already enabled and working, so essentially all I want is the ability to play an animation while the ItemContainerGenerator does it's thing.

推荐答案

尝试设置最绑定<一个href="http://msdn.microsoft.com/en-us/library/system.windows.data.binding.isasync%28v=vs.110%29.aspx"相对=nofollow> IsAsync = TRUE ：

Try setting most bindings to IsAsync=True:

<SomeControl SomeProperty="{Binding SomeData, IsAsync=True}"/>
