在ContentControl中托管模态对话框 [英] Hosting a modal dialog in a ContentControl

问题描述

而不是在我的MainWindow的中心托管我的模态对话框，我想在其MainWindow内的一个ContentControl中托管它。希望有人能告诉我如何去做这件事。谢谢。

Instead of hosting my modal dialog at the center of my MainWindow, I would like to host it within one of the ContentControls within my MainWindow. Hope someone can advise me how to go about this. Thanks.

推荐答案

我有一个例子，在 github 的自定义 FrameworkElement ，允许您在主要内容上显示模态内容。

I have an example on github of a custom FrameworkElement that allows you to display modal content over the primary content.

控件可以这样使用：

<c:ModalContentPresenter IsModal="{Binding DialogIsVisible}">
    <TabControl Margin="5">
            <Button Margin="55"
                    Padding="10"
                    Command="{Binding ShowModalContentCommand}">
                This is the primary Content
            </Button>
        </TabItem>
    </TabControl>

    <c:ModalContentPresenter.ModalContent>
        <Button Margin="75"
                Padding="50"
                Command="{Binding HideModalContentCommand}">
            This is the modal content
        </Button>
    </c:ModalContentPresenter.ModalContent>

</c:ModalContentPresenter>

功能：

• 在显示模态内容时不会禁用主要内容。


• 禁用鼠标和键盘访问


• 只对所覆盖的内容而不是整个应用程序进行模态。


• 可用于通过绑定到 IsModal 属性的MVVM友好的方式。

• Displays arbitrary content.
• Does not disable the primary content whilst the modal content is being displayed.
• Disables mouse and keyboard access to the primary content whilst the modal content is displayed.
• Is only modal to the content it is covering, not the entire application.
• can be used in an MVVM friendly way by binding to the IsModal property.
