如何避免在 MVVM 上下文中等待 Silverlight 模板化控件初始化
我正在尝试在应用程序中制作和使用模板化控件，但我似乎遇到了计时问题。当我使用自定义模板化控件时，在 XAML
所以问题是：
从 Themes\Generic.xaml 加载 ControlTemplate 是异步的吗？ 如何在 MVVM 上下文中使用这些多级模板化控件？
I'm trying to make and use templated controls in an application but I seem to run into timing isssues. When I use a custom templated control, in XAML <local:MyControl> and through code (new MyControl()), and call a method on the control that tries to do something with a control in the Controltemplate, a control in the template is almost always null even after the OnApplyTemplate method. One solution is to wait for the control to initialize, using an event thrown in the OnApplyTemplate method, and then let the code do something on the controls in the template but this seems to replicate control/framework features that I shouldn't have to worry about.
So the questions are:
Is the loading of the ControlTemplate from the Themes\Generic.xaml asynchronous?
How do I use these multiple level templated controls in a MVVM context?

在 OnApplyTemplate 中，您需要使用 GetTemplateChild 方法来访问控件。有关以下内容的说明，请参阅此处控制生命周期。
In OnApplyTemplate you need to use the GetTemplateChild method to get to the controls. See here for a description of the control lifecycle.
