C# 在xaml网格列中放置小部件

嗨，我把手机屏幕分成三行，第二行分成两列。我正在尝试将图像添加到第二行的第二列。虽然我在图像属性中指定了Grid.Row和Grid.Column，但它不起作用。请您指导我如何在不同的行和列中添加小部件

非常感谢你的帮助

<Grid>

    <Grid.RowDefinitions>
        <RowDefinition/>
        <RowDefinition/>
        <RowDefinition/>
    </Grid.RowDefinitions>

    <Grid Grid.Row="1">
        <Grid.ColumnDefinitions>
            <ColumnDefinition/>
            <ColumnDefinition/>                
        </Grid.ColumnDefinitions>
    </Grid>

    <Image
        HorizontalAlignment="Left"
        VerticalAlignment="Top"
        Width="100"
        Height="100"
        Grid.Row="0"
        Source="Assets/b_placeholder.jpg"/>
    <Image
        HorizontalAlignment="Left"
        VerticalAlignment="Top"
        Width="100"
        Height="100"
        Grid.Row="2"
        Source="Assets/b_placeholder.jpg"/>

    <Image
        HorizontalAlignment="Left"
        VerticalAlignment="Top"
        Width="100"
        Height="100"
        Grid.Row="1"
        Grid.Column="1"
        Source="Assets/b_placeholder.jpg"/>

</Grid>

不能仅在一行中定义列

您可以在该行中创建一个仅包含列的新网格：

<Grid>
    <Grid.RowDefinitions>
        <RowDefinition/>
        <RowDefinition/>
        <RowDefinition/>
    </Grid.RowDefinitions>   

    <Image
        HorizontalAlignment="Left"
        VerticalAlignment="Top"
        Width="100"
        Height="100"
        Grid.Row="0"
        Source="Assets/b_placeholder.jpg"/>

    <Grid Grid.Row="1">
        <Grid.ColumnDefinitions>
            <ColumnDefinition/>
            <ColumnDefinition/>                
        </Grid.ColumnDefinitions>
        <Image
            HorizontalAlignment="Left"
            VerticalAlignment="Top"
            Width="100"
            Height="100"            
            Grid.Column="1"
            Source="Assets/b_placeholder.jpg"/>
    </Grid>

    <Image
        HorizontalAlignment="Left"
        VerticalAlignment="Top"
        Width="100"
        Height="100"
        Grid.Row="2"
        Source="Assets/b_placeholder.jpg"/>
</Grid>

或者在第一张和第三张图片上处理columnspan：

<Grid>
    <Grid.RowDefinitions>
        <RowDefinition/>
        <RowDefinition/>
        <RowDefinition/>
    </Grid.RowDefinitions>  
    <Grid.ColumnDefinitions>
        <ColumnDefinition/>
        <ColumnDefinition/>                
    </Grid.ColumnDefinitions> 

    <Image
        HorizontalAlignment="Left"
        VerticalAlignment="Top"
        Width="100"
        Height="100"
        Grid.Row="0"
        Grid.ColumnSpan="2"
        Source="Assets/b_placeholder.jpg"/>

    <Image
        HorizontalAlignment="Left"
        VerticalAlignment="Top"
        Width="100"
        Height="100"  
        Grid.Row="1"          
        Grid.Column="1"
        Source="Assets/b_placeholder.jpg"/>

    <Image
        HorizontalAlignment="Left"
        VerticalAlignment="Top"
        Width="100"
        Height="100"
        Grid.Row="2"
        Grid.ColumnSpan="2"
        Source="Assets/b_placeholder.jpg"/>
</Grid>
