自定义对话框窗口棱镜 [英] Customize Dialog window prism

问题描述

我已经实现了新的 DialogService，如本期所示WPF 的新 IDialogService

I have implemented the new DialogService as shown in this issue A New IDialogService for WPF

然而，这并没有解释如何编辑对话框本身的窗口，因为 NotificationDialog 是一个 UserControl.

However, this doesn't explain how to edit the window of the dialog itself, since the NotificationDialog is a UserControl.

我尝试将其更改为 Window，但由于不是根窗口而引发异常.

I have tried changing it to a Window but then an exception is raised due to not being the root Window.

知道如何更改对话框的窗口吗?

由于标题和图标是在 DialogViewModelBase 中设置的，我也尝试添加一个 ResizeMode 属性.

Since the Title and the Icon is set in DialogViewModelBase, I have tried to add a ResizeMode property as well.

在DialogViewModelBase中:

private ResizeMode _resizeMode;
public ResizeMode ResizeMode
{
   get => _resizeMode;
   set => SetProperty(ref _resizeMode, value);
}

和在 NotificationDialogViewModel 实现中:

public NotificationDialogViewModel()
{
    Title = "Notification";
    ResizeMode = System.Windows.ResizeMode.CanMinimize;
    CloseDialogCommand = new DelegateCommand(CloseDialog);
}

但是它不能按预期工作.

However it doesn't work as intended.

推荐答案

Any idea how can I change the Window of the dialog?

查看 code，看来您必须实现 IDialogWindow 并将默认注册覆盖到内置实现中.

Looking at the code, it looks like you have to implement IDialogWindow and override the default registration to the built-in implementation.

另外，你不需要继承DialogViewModelBase，只需要实现IDialogAware就足够了.

Also, you don't need to inherit from DialogViewModelBase, just implementing IDialogAware suffices.
