Question

我正在使用c＃/ xaml为Windows商店开发一个应用程序。

的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;
    }

如何更改弹出窗口应放在窗口右上角的代码？

Answer 1

这取决于容纳PopUp元素的布局类型。试试这个

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

根据您的设置，除了上述内容之外，您可能需要将PopUp元素移动到网格中的新列。例如

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

如果它在Canvas中你可以使用

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