Question

我有一件物品,想展示我的习俗。

就像

String A
String B
String C

范围长期而言,A和B可以是多个方面,但C可起作用。我想到的是Hala=“Auto”和一个DockPanel。然而,A号楼的高度应该如此。还与Sting B公司合作。

这是我迄今提出的:

<ScrollViewer ScrollViewer.VerticalScrollBarVisibility="Auto" Background="Black">
    <ItemsControl Name="ItemsControl1">
        <ItemsControl.ItemsPanel>
            <ItemsPanelTemplate>
                <StackPanel Orientation="Vertical" />
            </ItemsPanelTemplate>
        </ItemsControl.ItemsPanel>
        <ItemsControl.ItemTemplate>
            <DataTemplate>
                <Border BorderBrush="#FF126eb1" BorderThickness="1.5" CornerRadius="8,8,8,8" Background="#FF074e84" Width="350" Height="Auto">
                    <DockPanel Width="350" Margin="0,10,0,0" Height="Auto" Background="Transparent">
                        <Canvas DockPanel.Dock="Top" Height="Auto" Width="350" Margin="0,10,0,0">
                            <TextBlock Text="{Binding Headline}" Canvas.Left="5" Canvas.Top="5" Foreground="White" FontSize="15" FontWeight="Bold" MaxWidth="340" TextWrapping="Wrap" Height="Auto"/>
                        </Canvas>
                        <Canvas DockPanel.Dock="Top" Height="Auto" Width="350" Margin="0,10,0,0">
                            <TextBlock Text="{Binding Description}" Canvas.Left="5" Canvas.Top="20" Foreground="White" FontSize="13" MaxWidth="340" TextWrapping="Wrap" Height="Auto" />
                        </Canvas>
                        <Canvas DockPanel.Dock="Top" Width="350" Height="40" Margin="0,10,0,0" Background="Transparent">
                            <TextBlock Text="{Binding DeadlineOn, StringFormat= Deadline: {0} }" Canvas.Left="5" Canvas.Top="5" Foreground="White"/>
                             <!-- and other controls -->
                        </Canvas>
                    </DockPanel>
                </Border>
            </DataTemplate>
        </ItemsControl.ItemTemplate>
    </ItemsControl>
</ScrollViewer>

遗憾的是,只有微额资产在Sting A和B中处于高位。

如果每个项目的高度不为人所知,我如何能够做到这一点?

Answer 1

有许多布局要素,虽然这给你很多选择,但很难确定哪一个布局要素是在特定情况下使用的权利。

In general, a Canvas is useful for its convenient fixed positioning capabilities. It allows anything to be placed anywhere using the Canvas.Left and Canvas.Top attached properties. But because the size of a Canvas is fixed and doesn t depend on its children, it s difficult to use for variable-sized content. The parent of the Canvas is "insulated" from the size of the children of the Canvas, and this is actually useful in some situations.

相比之下,<代码>Grid迄今为止是灵活的布局要素,并且有助于排出有或无间隙的电网。因此,在你创建新的<代码>Window或UserControl时,其缺席。但是,与<条码>Canvas不同,在未指明且未延伸到现有空间时,<条码>Grid>/code>的大小是其所有子女的大小。

www.un.org/Depts/DGACM/index_spanish.htm 还有一些财产,如果它有数名儿童,而且他们被排入牢房或一栏,他们就相互取而代之的是overed,后来子女在Z-order中的比例更高。这只是一个<条码>Canvas,但没有<条码>Canvas.Left和<条码>Canvas.Top,我们如何能够对子女的地位进行严格控制?

举一个例子。此处为<条码>Canvas,两条斜体为平方,空间不多,<条码>。做同样的事情:

<Grid>
    <StackPanel>
        <Canvas Height="120">
            <Rectangle Canvas.Left="10" Canvas.Top="10" Height="100" Width="100" Fill="Red"/>
            <Rectangle Canvas.Left="120" Canvas.Top="10" Height="100" Width="100" Fill="Green"/>
        </Canvas>
        <Grid HorizontalAlignment="Left">
            <Rectangle Margin="10,10,10,10" Height="100" Width="100" Fill="Red" HorizontalAlignment="Left"/>
            <Rectangle Margin="120,10,10,10" Height="100" Width="100" Fill="Green" HorizontalAlignment="Left"/>
        </Grid>
    </StackPanel>
</Grid>

在第一种情况下,我们必须具体说明<代码>Canvas的高度,因为它确实是自动的。在第二种情况下,我们使用<代码>Margin至模拟绝对定位和Grid的大小,以适应其内容。
