在Silverlight 3.0中,我可以在包含对事件处理程序的引用的外部文件中创建数据模板吗?

Is it possible to include an event handler reference in a data template that is not associated with the code-behind where the event handler is defined? I'm getting a PARSER-BAD-PROPERTY-VALUE when trying to pull this off.

是否可以在数据模板中包含事件处理程序引用,该数据模板与定义事件处理程序的代码隐藏无关?当我试图把它拉下来时,我得到了一个PARSER-BAD-PROPERTY-VALUE。

For example, let's say I have this very simple XAML.

例如,假设我有这个非常简单的XAML。

page.xaml

page.xaml

<DataTemplate x:Key="ItemsTemplate">
     <HyperlinkButton Click="HyperlinkButton_Click" />
</DataTemplate>

<ItemsControl ItemTemplate="{StaticResource ItemsTemplate}" />

This works fine since the event handler HyperlinkButton_Click is in the code-behind for page.xaml.

这很好用,因为事件处理程序HyperlinkBut​​ton_Click位于page.xaml的代码隐藏中。

BUT ... when I move the data template to another file ...

但是......当我将数据模板移动到另一个文件时......

resources.xaml

resources.xaml

<DataTemplate x:Key="ItemsTemplate">
     <HyperlinkButton Click="HyperlinkButton_Click" />
</DataTemplate>

page.xaml

page.xaml

<ItemsControl ItemTemplate="{StaticResource ItemsTemplate}" />

... Silverlight seems to lose track of what I'm doing and I get the PARSER-BAD-PROPERTY-VALUE error.

... Silverlight似乎忘记了我正在做的事情,我得到了PARSER-BAD-PROPERTY-VALUE错误。

I know you can not dynamically add controls that have event handlers, like in (XamlReader.Load(<"Button Click="handler".../>)). So maybe that's the reason why the Click in the external file does not work.

我知道你不能动态添加具有事件处理程序的控件,例如(XamlReader.Load(<“Button Click =”handler“... />))。所以也许这就是为什么外部文件中的Click不会工作。
