c# - 如何使uwp弹出全屏

问题描述

我正在为平板电脑创建一个应用程序，它将显示一个充满数据的网格。我希望能够单击每个项目，然后将该数据显示在弹出窗口或弹出窗口或其他对话框中，以便我可以像表单一样对其进行编辑。到目前为止，我正在使用一个包含堆栈面板的弹出窗口，如下所示：

            <Grid Background="{ThemeResource ApplicationPageBackgroundThemeBrush}" Margin="10 0 10 0">
    <GridView ItemsSource="{x:Bind Activities}" ItemsPanel="{StaticResource ResourceKey=ItemsPanelTemplate}">
        <GridView.ItemContainerStyle>
            <Style TargetType="GridViewItem">
                <Setter Property="HorizontalContentAlignment" Value="Stretch" />
            </Style>
        </GridView.ItemContainerStyle>
        <GridView.ItemTemplate>
            <DataTemplate x:DataType="model:TimActivity">
                <Grid Tapped="GridView_Tapped">
                    <Grid.ColumnDefinitions>
                        <ColumnDefinition Width="1*" />
                        <ColumnDefinition Width="1*" />
                        <ColumnDefinition Width="1*" />
                        <ColumnDefinition Width="1*" />
                        <ColumnDefinition Width="1*" />
                        <ColumnDefinition Width="2*" />
                        <ColumnDefinition Width="1*" />
                    </Grid.ColumnDefinitions>
                    <TextBlock Grid.Column="0" Text="{x:Bind Path=Type, Converter={StaticResource TimActivityTypeToStringConverter}}" />
                    <TextBlock Grid.Column="1" Text="{x:Bind StartTime}" />
                    <TextBlock Grid.Column="2" Text="{x:Bind EndTime}" />
                    <TextBlock Grid.Column="3" Text="{x:Bind From}" />
                    <TextBlock Grid.Column="4" Text="{x:Bind To}" />
                    <TextBlock Grid.Column="5" Text="{x:Bind Comment}" />
                    <TextBlock Grid.Column="6" Text="{x:Bind Path=Chargeable, Converter={StaticResource BoolToStringConverter}}" />
                    <FlyoutBase.AttachedFlyout>
                        <Flyout Placement="Full">
                            <StackPanel>
                                        <TextBlock Text="Activity"/>
                                        <TextBox  Text="{x:Bind Path=Type, Converter={StaticResource TimActivityTypeToStringConverter}}" />
                                        <TextBlock Text="Start Time"/>
                                        <TextBox  Text="{x:Bind StartTime}" />
                                        <TextBlock Text="End Time"/>
                                        <TextBox  Text="{x:Bind EndTime}" />
                                        <TextBlock Text="From"/>
                                        <TextBox  Text="{x:Bind From}" />
                                        <TextBlock Text="To"/>
                                        <TextBox  Text="{x:Bind To}" />
                                        <TextBlock Text="Comment"/>
                                        <TextBox  Text="{x:Bind Comment}" />
                                        <TextBlock Text="Chargeable?"/>
                                        <TextBox  Text="{x:Bind Path=Chargeable, Converter={StaticResource BoolToStringConverter}}" />
                            </StackPanel>
                        </Flyout>
                    </FlyoutBase.AttachedFlyout>
                </Grid>
            </DataTemplate>
        </GridView.ItemTemplate>
    </GridView>
</Grid>

我将设置Placement为Full，但它只会垂直拉伸弹出窗口，而不是全屏。你能告诉我一个。弹出是对此的正确控制，并且b。如何让它全屏？

解决方案

对于您的要求，我们建议您使用ConnectedAnimation方法。有关更多步骤，请参阅此代码示例。

private void TipsGrid_ItemClick(object sender, ItemClickEventArgs e)
{
    ConnectedAnimation animation = null;

    // Get the collection item corresponding to the clicked item.
    var container = collection.ContainerFromItem(e.ClickedItem) as GridViewItem;
    if (container != null)
    {
        // Stash the clicked item for use later. We'll need it when we connect back from the detailpage.
        _storedItem = Convert.ToInt32(container.Content);

        // Prepare the connected animation.
        // Notice that the stored item is passed in, as well as the name of the connected element. 
        // The animation will actually start on the Detailed info page.
        animation = collection.PrepareConnectedAnimation("forwardAnimation", _storedItem, "connectedElement");

    }

    SmokeGrid.Visibility = Visibility.Visible;
   // SmokeGrid.DataContext = e.ClickedItem;
    animation.TryStart(destinationElement);
}

更新

然后我应该能够编辑该表单中的所有字段，保存后，它会反映在网格中。

您可以创建继承模型INotifyPropertyChanged，然后使用双向绑定将模型属性与 xaml 代码绑定。

<GridView Name="collection" ItemClick="Conllection_ItemClick" IsItemClickEnabled="True">
    <GridView.ItemTemplate>
        <DataTemplate>
            <Grid x:Name="connectedElement"  Height="100" Width="100" Background="Orange">
                <Grid.RowDefinitions>
                    <RowDefinition Height="Auto" />
                    <RowDefinition Height="*" />
                </Grid.RowDefinitions>
                <TextBlock Text="{Binding Title}" 
                           VerticalAlignment="Center"
                           HorizontalAlignment="Center"
                           TextAlignment="Center"/>
                <TextBlock Grid.Row="1" Text="{Binding Content,Mode=TwoWay}" 
                           VerticalAlignment="Center"
                           HorizontalAlignment="Center"
                           TextAlignment="Center"/>

            </Grid>
        </DataTemplate>
    </GridView.ItemTemplate>
</GridView>

GridView您可以在ItemClick时将项目传递给弹出网格。

private void Conllection_ItemClick(object sender, ItemClickEventArgs e)
{
    ConnectedAnimation animation = null;
    var container = collection.ContainerFromItem(e.ClickedItem) as GridViewItem;
    if(container != null)
    {
        _storedItem = container.Content;
        animation = collection.PrepareConnectedAnimation("forwardAnimation", _storedItem, "connectedElement");
    }
    SmokeGrid.Visibility = Visibility.Visible;
   // pass the item DataContext.
    SmokeGrid.DataContext = e.ClickedItem;

    animation.TryStart(destinationElement);
}
