将网格RowDefinition高度绑定到ColumnDefinition宽度

Question

我正在尝试将RowDefinition的高度绑定到ReferenceColumn的宽度。

<Grid x:Name="SelectionElements">
    <Grid.RowDefinitions>
        <RowDefinition Height="{Binding Path=Width.Value, ElementName=ReferenceColumn}" />
        <RowDefinition Height="{Binding Path=Width.Value, ElementName=ReferenceColumn}" />
        <RowDefinition Height="{Binding Path=Width.Value, ElementName=ReferenceColumn}" />
        <RowDefinition Height="{Binding Path=Width.Value, ElementName=ReferenceColumn}" />
    </Grid.RowDefinitions>
    <Grid.ColumnDefinitions>
        <ColumnDefinition x:Name="ReferenceColumn" Width="*" />
        <ColumnDefinition Width="*" />
    </Grid.ColumnDefinitions>
</Grid>

但它不起作用（没有错误或任何其他）。

Answer 1

设置实际宽度：

    <Grid.RowDefinitions>
        <RowDefinition Height="{Binding Path=ActualWidth, ElementName=ReferenceColumn}" />
        <RowDefinition Height="{Binding Path=ActualWidth, ElementName=ReferenceColumn}" />
        <RowDefinition Height="{Binding Path=ActualWidth, ElementName=ReferenceColumn}" />
        <RowDefinition Height="{Binding Path=ActualWidth, ElementName=ReferenceColumn}" />
    </Grid.RowDefinitions>
    <Grid.ColumnDefinitions>
        <ColumnDefinition x:Name="ReferenceColumn" Width="*" />
        <ColumnDefinition Width="*" />
    </Grid.ColumnDefinitions>

Answer 2

使用ActualWidth而不是Width。
