问题描述

请参阅Prism 手册我制作了模态视图并将其粘贴到主视图中，如下所示:

但是我在 中遇到了编译时错误(在运行时一切都很完美):<块引用>

错误 3 无法将PopupWindowAction"类型的值添加到TriggerActionCollection"类型的集合或字典中.

在我的项目中，我使用 PRISM 5 和 .NET 4.5

UDP:

命名空间的定义(在 baseView:BaseView 中)如下:

xmlns:prism="http://www.codeplex.com/prism";xmlns:i=http://schemas.microsoft.com/expression/2010/interactivity"

解决方案

您使用的是 Visual Studio 2015 吗?我在 VS 2015 中遇到了类似的问题，但在 VS 2013 中没有，我首先认为 Prism 框架中的二进制文件有问题.我在 Prism GitHub 上发布了一个问题:

https://github.com/PrismLibrary/Prism/issues/213

最终对我有用的事情是重新安装 VS 2015.我怀疑 VS 2015 的一些可选扩展/插件导致了这个问题.希望这也能解决您的问题.

Refer to Prism manual I made my modal view and pasted it in main view like this:

<baseView:BaseView ... >
    <i:Interaction.Triggers>
        <prism:InteractionRequestTrigger SourceObject="{Binding DocumentSelectionRequest, Mode=OneWay}">
            <prism:PopupWindowAction IsModal="True">
                <prism:PopupWindowAction.WindowContent>
                    <modal:DocumentSelectionView />
                </prism:PopupWindowAction.WindowContent>
            </prism:PopupWindowAction>
        </prism:InteractionRequestTrigger>
    </i:Interaction.Triggers>
<Grid>
...
</Grid>
</baseView:BaseView>

But I have got the compile time error in <prism:PopupWindowAction IsModal="True"> (in run time everything is perfect):

Error 3 A value of type 'PopupWindowAction' cannot be added to a collection or dictionary of type 'TriggerActionCollection'.

In my project I use PRISM 5 and .NET 4.5

UDP:

Namespaces are defined (in baseView:BaseView) like:

xmlns:prism="http://www.codeplex.com/prism"
xmlns:i="http://schemas.microsoft.com/expression/2010/interactivity"

解决方案

Are you using Visual Studio 2015? I was having a similar problem with VS 2015, but not in VS 2013, and I first thought something was wrong with the binaries from the Prism framework. I posted an issue on the Prism GitHub:

https://github.com/PrismLibrary/Prism/issues/213

The thing that worked for me, eventually, was reinstalling VS 2015. I suspect that some of the optional extensions/plugins for VS 2015 was causing the problem. Hopefully this will solve your troubles too.
