问题陈述是：
我在我的wpf项目中使用自定义弹出窗口。我可以使用自定义弹出窗口和自定义用户控件。在那里，我可以在用户控件属性中提供宽度和高度，并且弹出窗口大小也是定义的。但问题是当我调整弹出窗口的大小时，额外的地方充满了空白空间，但我已将自定义控件设置为网格并设置为相应调整大小。但是如果我没有在自定义控件中设置宽度和高度，则调整大小的效果非常好。我的问题是：有什么方法可以告诉棱镜设置窗口大小，如在用户控件中定义的那样。
非常感谢任何帮助。
这用于shell属性：

我用以下代码调用弹出窗口：
_regionManager.Regions[RegionNames.MainRegion].RequestNavigate("/AppSettingsView");
答案 0 :(得分：1)
我很欣赏这个问题已经很老了，但希望这能帮助任何尝试做同样事情的人！
在棱镜库中，您可以访问一项名为对话服务的功能，该功能允许您轻松调用弹出窗口并完全访问其窗口属性。
为了创建注册对话框，创建一个模块并使用容器注册表将其注册为对话框。您使用的视图模型必须继承 IDialogAware 才能工作。
containerRegistry.RegisterDialog<View, ViewModel>("DialogName");
然后从任何地方打开对话框
dialogService.ShowDialog("DialogName")
使用此模式时，您可以使用用户控件中的prism:Dialog.WindowStyle 标记设置窗口的属性
<UserControl x:Class="TestApp.Shell"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
xmlns:d="http://schemas.microsoft.com/expression/blend/2008"
xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"
xmlns:prism="http://prismlibrary.com">
<prism:Dialog.WindowStyle>
<Style TargetType="Window">
<Setter Property="ResizeMode" Value="NoResize" />
<Setter Property="Width" Value="880" />
<Setter Property="Height" Value="780" />
</Style>
</prism:Dialog.WindowStyle>
</UserControl>
您可以在对话调用中使用额外的参数，以便将数据传入和传出对话，对话服务的文档中对此进行了介绍 here
