UWP网格填充父窗口

Question

我们正在开展一个学校项目并陷入了死胡同.我们正在尝试grid填充整个父窗口,但我们根本无法这样做.

这就是设计师展示的内容以及我们希望它的外观:

这就是我们运行它时的样子:

这是我们的xaml代码:

<Grid x:Name="Grid" HorizontalAlignment="Stretch" VerticalAlignment="Stretch" Width="{Binding ActualWidth, RelativeSource = {RelativeSource Mode=TemplatedParent}}" Height="{Binding ActualHeight, RelativeSource ={RelativeSource Mode=TemplatedParent}}">
    <Grid.Background>
        <ImageBrush Stretch="UniformToFill" ImageSource="Assets/france_countryside.jpg" Opacity="0.4" />
    </Grid.Background>

    <!--Search section-->

    <RelativePanel HorizontalAlignment="Stretch" VerticalAlignment="Stretch" Width="{Binding ElementName=Grid,Path=ActualWidth}">
        <TextBlock Text="Find available apartment" FontSize="24" Margin="30" RelativePanel.AlignHorizontalCenterWithPanel="True" />
        <AutoSuggestBox Name="AutoSuggestBox" 
                        PlaceholderText="Search" 
                        Width="300" 
                        RelativePanel.AlignHorizontalCenterWithPanel="True" 
                        Margin="0,100,0,0"
                        TextChanged="AutoSuggestBox_OnTextChanged"
                        Header="Destination:"/>
        <CalendarDatePicker Name="CheckInPicker" Header="Check in:" RelativePanel.Below="AutoSuggestBox" RelativePanel.AlignLeftWith="AutoSuggestBox" Margin="0,40,0,0" PlaceholderText="select a date" IsTodayHighlighted="False"/>
        <CalendarDatePicker Name="CheckOutPicker" Header="Check out:" RelativePanel.Below="AutoSuggestBox" RelativePanel.AlignRightWith="AutoSuggestBox" Margin="0,40,0,0"/>
        <ComboBox x:Name="numberOfGuestsBox"  Width="127" RelativePanel.Below="CheckInPicker" RelativePanel.AlignLeftWith="AutoSuggestBox" Margin="0,30,0,0" PlaceholderText="Choose" Header="Guests:" FontSize="15">
            <x:String>1</x:String>
            <x:String>2</x:String>
            <x:String>3</x:String>
            <x:String>4</x:String>
            <x:String>5</x:String>
            <x:String>6</x:String>
            <x:String>7</x:String>
            <x:String>8</x:String>
            <x:String>9</x:String>
            <x:String>10</x:String>
        </ComboBox>
        <ToggleSwitch Header="Smoking allowed?" Margin="0,30,0,0" RelativePanel.Below="CheckOutPicker" RelativePanel.AlignLeftWith="CheckOutPicker" OffContent="Eew - No!" OnContent="Ya man!"/>
        <Button x:Name="SearchButton" Content="Search available apartments" RelativePanel.Below="numberOfGuestsBox" RelativePanel.AlignHorizontalCenterWithPanel="True" Margin="0,30,0,30" Width="300" Height="50" Background="MediumSeaGreen" Foreground="AliceBlue" Click="SearchButton_Click"/>
    </RelativePanel>
</Grid>

我们该如何解决这个问题？
我们已经尝试过什么对我们来说似乎是拉伸的一切 保证金不是真正的选择,因为我们希望它能够重新调整大小.

看起来(对我们来说)网格适合相对面板并缩小到那个尺寸.我们有点确定,如果我们让网格适合窗口的屏幕尺寸,相对面板将放在中间.感谢您的帮助!

编辑:

我们在可能导致问题的框架内保留"视图".当我重新调整帧大小时,图像重新调整大小并且splitview移动到"中间",但缩放不适用于splitview和图片.

以下是splitview的代码:

    <!--Split View-->
    <SplitView Name="MySplitView" 
               Grid.Row="1" 
               DisplayMode="CompactOverlay" 
               OpenPaneLength="200" 
               CompactPaneLength="48" 
               HorizontalAlignment="Left">

        <!--SplitView Pane for icons-->
        <SplitView.Pane>
            <ListBox Name="IconsLIstBox" SelectionMode="Single" SelectionChanged="IconsLIstBox_OnSelectionChanged">
                <ListBoxItem Name="HomeListItem">
                    <StackPanel Orientation="Horizontal">
                        <TextBlock FontFamily="Segoe MDL2 Assets" FontSize="24" Text="&#xE10F;"/>
                        <TextBlock Text="Home" Margin="20,0,0,0"/>
                    </StackPanel>
                </ListBoxItem>
                <ListBoxItem Name="LocationsListBoxItem">
                    <StackPanel Orientation="Horizontal">
                        <TextBlock FontFamily="Segoe MDL2 Assets" FontSize="24" Text="&#xE1D1;"/>
                        <TextBlock Text="Locations" Margin="20,0,0,0"/>
                    </StackPanel>
                </ListBoxItem>
                <ListBoxItem Name="MostPopularListBoxItem">
                    <StackPanel Orientation="Horizontal">
                        <TextBlock FontFamily="Segoe MDL2 Assets" FontSize="24" Text="&#xE24A;"/>
                        <TextBlock Text="Most Popular" Margin="20,0,0,0"/>
                    </StackPanel>
                </ListBoxItem>
                <ListBoxItem Name="MapListBoxItem">
                    <StackPanel Orientation="Horizontal">
                        <TextBlock FontFamily="Segoe MDL2 Assets" FontSize="24" Text="&#xE128;"/>
                        <TextBlock Text="Map" Margin="20,0,0,0"/>
                    </StackPanel>
                </ListBoxItem>
                <ListBoxItem Name="ProfileListBoxItem">
                    <StackPanel Orientation="Horizontal">
                        <TextBlock FontFamily="Segoe MDL2 Assets" FontSize="24" Text="&#xE170;"/>
                        <TextBlock Text="Profile" Margin="20,0,0,0"/>
                    </StackPanel>
                </ListBoxItem>
                <ListBoxItem Name="ContactListBoxItem">
                    <StackPanel Orientation="Horizontal">
                        <TextBlock FontFamily="Segoe MDL2 Assets" FontSize="24" Text="&#xE166;"/>
                        <TextBlock Text="Contact" Margin="20,0,0,0"/>
                    </StackPanel>
                </ListBoxItem>
            </ListBox>
        </SplitView.Pane>

        <!--SplitView Content-->
        <Frame x:Name="MyFrame" HorizontalAlignment="Left" Width="1043"/>
    </SplitView>

</Grid>

我们已经尝试将框架放在一个内部,splitview.content但两者之间没有区别.

你想努力:)有时候XAML很容易.

容器控件喜欢Grid并RelativePanel自动缩放到其父级的完整可用大小,而其他类似StackPanel只会增长到其子元素所需的最小大小.只有后者需要HorizontalAlignment="Stretch"并VerticalAlignment="Stretch"填充屏幕.永远不要绑定宽度/高度属性.

这应该足以全屏显示(如果您的网格直接在页面下,而不是在一个StackPanel或类似的控件中):

<Grid x:Name="Grid">
    <Grid.Background>
        <ImageBrush Stretch="UniformToFill" ImageSource="Assets/france_countryside.jpg" Opacity="0.4" />
    </Grid.Background>

    <!--Search section-->

    <RelativePanel>
        ...
    </RelativePanel>
</Grid>

编辑以回复问题中splitview的添加代码:

我注意到了两个SplitView并且Frame有HorizontAlignment="Left".这就是说:"而不是使用我的全屏,只使用你最不需要的任何尺寸并对齐左边".删除这些作业和你的宽度Frame.当您想要填充父控件时,防止使用对齐(左/右/中)或大小(宽度/高度).

<!--Split View-->
<SplitView Name="MySplitView" 
           Grid.Row="1" 
           DisplayMode="CompactOverlay" 
           OpenPaneLength="200" 
           CompactPaneLength="48">
....

    <!--SplitView Content-->
    <Frame x:Name="MyFrame" />
</SplitView>
