Question

我有一个包含堆栈面板的Group Box，其中包含一个组合框（A）和一个文本框。我有另一个堆栈面板（B），其中包含一个组合框和一个标签。我会使用xaml代码将组合框B放在与组合框A（相同的y）相同的级别上。请注意，GroupBox和Stack Panel（B）放在同一行，不同列的网格中。

我正在尝试将组合框（B）的y坐标绑定到组合框（A）的y坐标。

我可以在Visual Studio属性窗口中找到wpf控件的坐标信息吗？

<Grid>

使用y坐标的近似值将使用Margin属性...但是在第一次调整大小后它将会中断。

我认为，可以在调整大小时更新Margin，但我会从更复杂的布局开始，如下所示：

<Grid>
    <Grid.RowDefinitions>
        <RowDefinition Height="*" />
        <RowDefinition Height="*" />
        <RowDefinition Height="*" />
    </Grid.RowDefinitions>
    <Grid.ColumnDefinitions>
        <ColumnDefinition Width="*" />
        <ColumnDefinition Width="*" />
    </Grid.ColumnDefinitions>

   <!--additional Grid used to position comboBoxes on the same height-->
    <Grid Grid.Row="1" Grid.Column="0" Grid.ColumnSpan="2">
        <Grid.RowDefinitions>
            <RowDefinition/>
            <RowDefinition Height="Auto"/>
            <RowDefinition/>
        </Grid.RowDefinitions>

        <Grid.ColumnDefinitions>
            <ColumnDefinition/>
            <ColumnDefinition/>
        </Grid.ColumnDefinitions>

        <!--group box is used as cover for the 1st column-->
        <GroupBox Name="AGroupBox" 
                  Grid.Row="0" Grid.RowSpan="3" Grid.Column="0"  >
            <GroupBox.Header>
                <Label Content="GroupBox" FontWeight="Bold" />
            </GroupBox.Header>
        </GroupBox>

        <!--stack panel with ComboBoxA is centered vertically in the 1st column-->
        <StackPanel Grid.Row="1" Grid.Column="0" 
                    Margin="5,0"
                    Orientation="Horizontal">
            <ComboBox x:Name="ComboBoxA" Width="100" Height="25" VerticalAlignment="Center"/>
            <TextBlock x:Name="TextBlockA" Width="150" VerticalAlignment="Center" Margin="10,0,0,0" Text="This a Test" />
        </StackPanel>

        <!--ComboBoxB is centered vertically in the 2nd column-->
        <ComboBox x:Name="ComboBoxB" 
                  Grid.Row="1" Grid.Column="1" 
                  VerticalAlignment="Top" HorizontalAlignment="Left"
                  Width="150" Height="25"/>

        <!--Label attached on top of ComboBoxB-->
        <Label x:Name="LabelB" Content="LabelB" 
               Grid.Row="0" Grid.Column="1" VerticalAlignment="Bottom"/>
    </Grid>
</Grid>
