這是一個和我一起玩,我似乎無法弄清楚 - 我需要一些外部幫助在這裏兄弟!WPF - PRISM:如何使用按鈕點擊關閉CustomPopupWindow
我想要一個沒有標題,最小化,最大化和關閉按鈕的彈出窗口,因爲我們想自己設計樣式,並在彈出窗口的屏幕上添加一個自定義關閉按鈕。
所以我跟着這些鏈接來獲得現在的我:

但我仍然無法弄清楚如何實現這一目標。基本的窗口有「確定」和「取消」按鈕,但這些都是默認設置,我不想這樣做,這就是爲什麼我選擇「自定義視圖」的原因。
這裏是我的主窗口的XAML:
<Window x:Class="Prototype.Views.MainWindow"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
xmlns:prism="http://prismlibrary.com/"
prism:ViewModelLocator.AutoWireViewModel="True"
xmlns:i="clr-namespace:System.Windows.Interactivity;assembly=System.Windows.Interactivity"
xmlns:views="clr-namespace:Prototype.Views"
Height="349.146" Width="727.317"
WindowState="Maximized">
<Grid>
<Button Command="{Binding RaiseCustomPopupViewCommand}">Show Popup Window</Button>
<i:Interaction.Triggers>
<prism:InteractionRequestTrigger SourceObject="{Binding CustomPopupViewRequest, Mode=OneWay}">
<prism:PopupWindowAction IsModal="True" CenterOverAssociatedObject="True">
<prism:PopupWindowAction.WindowStyle>
<Style TargetType="Window">
<Setter Property="ShowInTaskbar" Value="False"/>
<Setter Property="WindowStyle" Value="None"/>
<Setter Property="ResizeMode" Value="NoResize"/>
</Style>
</prism:PopupWindowAction.WindowStyle>
<prism:PopupWindowAction.WindowContent>
<views:CustomPopupView />
</prism:PopupWindowAction.WindowContent>
</prism:PopupWindowAction>
</prism:InteractionRequestTrigger>
</i:Interaction.Triggers>
</Grid>
</Window>
這裏,它的主窗口的代碼:
public class MainWindowViewModel : BindableBase
{
public InteractionRequest<INotification> CustomPopupViewRequest { get; private set; }
public MainWindowViewModel()
{
CustomPopupViewRequest = new InteractionRequest<INotification>();
}
public DelegateCommand RaiseCustomPopupViewCommand => new DelegateCommand(RaiseCustomPopupView, CanRaiseCustomPopupView);
public string InteractionResultMessage { get; private set; }
private void RaiseCustomPopupView()
{
InteractionResultMessage = "";
CustomPopupViewRequest.Raise(new Notification { Content = "Message for the CustomPopupView", Title = "Custom Popup" });
}
private bool CanRaiseCustomPopupView()
{
return true;
}
}
的InteractionRequestTrigger
的SourceObject是一個用戶控件。
這裏是它的XAML:
<UserControl x:Class="Prototype.Views.CustomPopupView"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"
xmlns:d="http://schemas.microsoft.com/expression/blend/2008"
xmlns:prism="http://prismlibrary.com/"
prism:ViewModelLocator.AutoWireViewModel="True"
xmlns:local="clr-namespace:Prototype.Views"
mc:Ignorable="d"
d:DesignHeight="300" d:DesignWidth="300"
MinWidth="300" MinHeight="100">
<StackPanel Orientation="Vertical" Background="Gray">
<Button DockPanel.Dock="Right"
Content="Close"/>
</StackPanel>
</UserControl>
因此,大家可以看到,我在用戶控件一個「關閉」按鈕。
我嘗試使用命令,但即使如此,我無法訪問窗口或執行某些關閉窗口。
是否有某種棱鏡命令或我不知道的東西?
是否可以通過按鈕按照我想要的方式關閉窗口?
任何幫助將不勝感激! :)
很高興看到你解決了你自己的問題。僅供參考,最新的棱鏡文檔可以在這裏找到:http://prismlibrary.readthedocs.io/en/latest/。無需爲此使用過時的MSDN文章。 –
