将弹出窗口放在XAML中窗口的右上角

Question

我正在使用c＃/ xaml开发适用于Windows商店的应用程序。

Xaml：

     <Popup x:Name="EditQuantityPopup"
           x:Uid="EditQuantityPopup"
           AutomationProperties.AutomationId="EditQuantityPopup"
           IsLightDismissEnabled="True"
           IsOpen="{Binding IsEditPopupOpened, Mode=TwoWay}">
        <Grid x:Name="PopupPanel"
              Background="{StaticResource ApplicationPageBackgroundThemeBrush}"
              Opacity=".9"
              Height="100"
              Width="230">


            <Grid x:Name="ContentPopupGrid"
                  Grid.Row="1"
                  Margin="20,0,10,15">
                <Grid.ColumnDefinitions>
                    <ColumnDefinition Width="Auto" />
                    <ColumnDefinition Width="10"/>
                    <ColumnDefinition Width="Auto" />
                    <!--<ColumnDefinition />-->
                </Grid.ColumnDefinitions>

                <TextBlock Grid.Column="0"


                       Text="{Binding Text}"
                           VerticalAlignment="Center"
                       TextTrimming="WordEllipsis"
                       FontSize="15"
                       Foreground="White"></TextBlock>
                <ProgressRing Grid.Column="2" IsActive="{Binding LoadingData}" Height="75" Width="75"></ProgressRing>

            </Grid>
        </Grid>
    </Popup>

将弹出窗口放置在底部应用栏顶部的代码：

        private void EditQuantityPopup_Opened(object sender, object e)
    {
        int margin = 10;
        int appbarHeight = 90;
        EditQuantityPopup.HorizontalOffset = margin;
        EditQuantityPopup.VerticalOffset = Window.Current.CoreWindow.Bounds.Bottom - appbarHeight - PopupPanel.Height - margin;
    }

如何更改将弹出窗口放置在窗口右上角的代码？

Answer 1

这取决于布局类型或容纳您的PopUp元素的类型。 尝试这个

EditQuantityPopup.HorizontalAlignment = Windows.UI.Xaml.HorizontalAlignment.Right;
EditQuantityPopup.VerticalAlignment = Windows.UI.Xaml.VerticalAlignment.Top;

除了上述内容之外，还取决于您的设置，您可能必须将PopUp元素移动到网格中的新列。 例如

Grid.SetColumn(EditQuantityPopup, [your column number]);

如果在画布中，则可以使用

var left = Window.Current.Bounds.Width - EditQuantityPopup.ActualWidth;
Canvas.SetLeft(EditQuantityPopup, left);
Canvas.SetTop(EditQuantityPopup, 0);

希望能有所帮助
