自定义对话框窗口棱镜

Alb*_*nso 2 c# wpf prism mvvm

我已经实现了新的 DialogService,如本期 A New IDialogService for WPF 所示

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

我曾尝试将其更改为 aWindow但由于不是根窗口而引发异常。

知道如何更改对话框的窗口吗?

由于标题和图标设置在 中DialogViewModelBase,我也尝试添加一个ResizeMode属性。

DialogViewModelBase

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

并在NotificationDialogViewModel实施中:

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

但是,它不能按预期工作。

对于搜索此内容的其他人 - 可以使用prism:Dialog.WindowStyle.

来自https://github.com/PrismLibrary/Prism/blob/master/Sandbox/Wpf/HelloWorld/HelloWorld/Dialogs/NotificationDialog.xaml 的示例

也可以使用 设置其他属性Setter。例如,

<Setter Property="WindowStyle" Value="None" />

将隐藏标题栏。
