如何限制另一个列的高度?

发布于 2024-10-10 05:34:42 字数 1473 浏览 2 评论 0原文

我在 WPF 中有一个网格,它由 4 行和 2 列组成,其中第 1 列包含一个图像控件,第 2 列包含 4 个文本块。问题是,图像控件将自身大小调整为图像大小,并将列表框的条目扩展太多[它在数据模板中],并使所有内容看起来都扭曲了。我不想手动设置最大高度/宽度,因为我希望图像将自身大小调整为它旁边的 4 个文本块的大小。有什么想法吗?

<DataTemplate>
                <Grid>
                    <Grid.ColumnDefinitions>
                        <ColumnDefinition />
                        <ColumnDefinition Width="*"/>
                    </Grid.ColumnDefinitions>
                    <Grid.RowDefinitions>
                        <RowDefinition Height="Auto"/>
                        <RowDefinition Height="Auto"/>
                        <RowDefinition Height="Auto"/>
                        <RowDefinition Height="Auto"/>
                    </Grid.RowDefinitions>
                    <Image Source="{Binding Logo, Converter={StaticResource BSConverter}}" Grid.Row="0" Grid.RowSpan="4" 
                           Grid.Column="0" Stretch="Uniform" SnapsToDevicePixels="True"/>
                    <TextBlock Text="{Binding Name}" Grid.Row="0" Grid.Column="1"/>
                    <TextBlock Text="{Binding Author}" Grid.Row="1" Grid.Column="1"/>
                    <TextBlock Text="{Binding Version}" Grid.Row="2" Grid.Column="1"/>
                    <TextBlock Text="{Binding Description}" Grid.Row="3" Grid.Column="1"/>
                </Grid>
            </DataTemplate>

提前致谢

I have a grid in WPF which is made of 4 rows along 2 columns where column 1 holds an Image control and column 2 holds 4 Textblocks. Problem is, the Image control sizes itself to the Image size and extends the listbox's entry too much [Its in a DataTemplate] and makes everything look distorted. I dont want to manually set a max height/width because i want the Image to size itself to the size of the 4 textblocks that are alongside it. Any ideas?

<DataTemplate>
                <Grid>
                    <Grid.ColumnDefinitions>
                        <ColumnDefinition />
                        <ColumnDefinition Width="*"/>
                    </Grid.ColumnDefinitions>
                    <Grid.RowDefinitions>
                        <RowDefinition Height="Auto"/>
                        <RowDefinition Height="Auto"/>
                        <RowDefinition Height="Auto"/>
                        <RowDefinition Height="Auto"/>
                    </Grid.RowDefinitions>
                    <Image Source="{Binding Logo, Converter={StaticResource BSConverter}}" Grid.Row="0" Grid.RowSpan="4" 
                           Grid.Column="0" Stretch="Uniform" SnapsToDevicePixels="True"/>
                    <TextBlock Text="{Binding Name}" Grid.Row="0" Grid.Column="1"/>
                    <TextBlock Text="{Binding Author}" Grid.Row="1" Grid.Column="1"/>
                    <TextBlock Text="{Binding Version}" Grid.Row="2" Grid.Column="1"/>
                    <TextBlock Text="{Binding Description}" Grid.Row="3" Grid.Column="1"/>
                </Grid>
            </DataTemplate>

Thanks in advance

您可以在父列表框上使用 Grid.IsSharedSizeGroup 来确保所有项目的第一列具有相同的宽度,如下所示

<ListBox ...
         Grid.IsSharedSizeScope="True">
    <ListBox.ItemTemplate>
        <DataTemplate>
            <Grid>
                <Grid.ColumnDefinitions>
                    <ColumnDefinition SharedSizeGroup="GroupA"/>
                    <ColumnDefinition Width="*"/>
                </Grid.ColumnDefinitions>
                ...

对于图像高度问题,您可以将 Height 绑定到父网格的 ActualHeight,并将 FallbackValue 设置为 1.0 (确保图像的高度不会影响网格的高度)

<Image Source="{Binding Logo, Converter={StaticResource BSConverter}}"
       Grid.Row="0"
       Grid.RowSpan="4"
       Grid.Column="0"
       Stretch="Uniform" SnapsToDevicePixels="True"
       Height="{Binding RelativeSource={RelativeSource AncestorType=Grid},
                        Path=ActualHeight,
                        FallbackValue=1.0}"/>

You can use Grid.IsSharedSizeGroup on the Parent ListBox to make sure all of your items get the same Width for the first Column like this

<ListBox ...
         Grid.IsSharedSizeScope="True">
    <ListBox.ItemTemplate>
        <DataTemplate>
            <Grid>
                <Grid.ColumnDefinitions>
                    <ColumnDefinition SharedSizeGroup="GroupA"/>
                    <ColumnDefinition Width="*"/>
                </Grid.ColumnDefinitions>
                ...

For the Image height problem, you could bind Height to the ActualHeight of the Parent Grid with a FallbackValue of 1.0 (to ensure the Height of the Image doesn't effect the Height of the Grid)

<Image Source="{Binding Logo, Converter={StaticResource BSConverter}}"
       Grid.Row="0"
       Grid.RowSpan="4"
       Grid.Column="0"
       Stretch="Uniform" SnapsToDevicePixels="True"
       Height="{Binding RelativeSource={RelativeSource AncestorType=Grid},
                        Path=ActualHeight,
                        FallbackValue=1.0}"/>

稍微修改容器以将 StackPanelGrid 结合使用,并通过 ElementName 绑定引用 StackPanel应该为您提供您正在寻找的视觉效果......

<DataTemplate>
    <Grid HorizontalAlignment="Left" VerticalAlignment="Top">
        <Grid.ColumnDefinitions>
            <ColumnDefinition/>
            <ColumnDefinition Width="*"/>
        </Grid.ColumnDefinitions>
        <Image VerticalAlignment="Top" HorizontalAlignment="Right" Margin="0,0,8,0" Source="{Binding Logo, Converter={StaticResource BSConverter}}" 
                           Grid.Column="0" Stretch="Uniform" SnapsToDevicePixels="True" 
           Height="{Binding ElementName=Contents, Path=ActualHeight}"/>

        <StackPanel VerticalAlignment="Top" Name="Contents" Grid.Column="1" Orientation="Vertical">
            <TextBlock Text="{Binding Name}"/>
            <TextBlock Text="{Binding Author}"/>
            <TextBlock Text="{Binding Version}"/>
            <TextBlock Text="{Binding Description}"/>
        </StackPanel>
    </Grid>
</DataTemplate>

Modifying your containers slightly to make use of a StackPanel in conjunction with a Grid and referencing the StackPanel via ElementName binding should provide you the visuals you are looking for...

<DataTemplate>
    <Grid HorizontalAlignment="Left" VerticalAlignment="Top">
        <Grid.ColumnDefinitions>
            <ColumnDefinition/>
            <ColumnDefinition Width="*"/>
        </Grid.ColumnDefinitions>
        <Image VerticalAlignment="Top" HorizontalAlignment="Right" Margin="0,0,8,0" Source="{Binding Logo, Converter={StaticResource BSConverter}}" 
                           Grid.Column="0" Stretch="Uniform" SnapsToDevicePixels="True" 
           Height="{Binding ElementName=Contents, Path=ActualHeight}"/>

        <StackPanel VerticalAlignment="Top" Name="Contents" Grid.Column="1" Orientation="Vertical">
            <TextBlock Text="{Binding Name}"/>
            <TextBlock Text="{Binding Author}"/>
            <TextBlock Text="{Binding Version}"/>
            <TextBlock Text="{Binding Description}"/>
        </StackPanel>
    </Grid>
</DataTemplate>
