我在网格中有一个标签和一个按钮。我正在尝试使按钮的高度与标签相匹配。
当前XAML:
<Grid>
<Grid.ColumnDefinitions>
<ColumnDefinition Width="Auto"/>
<ColumnDefinition Width="*"/>
</Grid.ColumnDefinitions>
<!-- vessel label and button -->
<Label StyleClass="headerSub" Grid.Column="0" x:Name="currentVesselLabel"
Text="huidig voertuig:"/>
<Button Grid.Column="1" Text="selecteer voertuig"
BindingContext="{x:Reference currentVesselLabel}"
HeightRequest="{Binding Path=HeightRequest}"
ClassId="selectVesselButton" x:Name="selectVesselButton"/>
</Grid>
我尝试将BindingContext
设置为标签,并将按钮的HeightRequest
属性绑定到Label的Height
和HeightRequest
属性。但是,两者都不起作用。如何将按钮的高度绑定到标签的高度?
答案 0 :(得分:0)
原因:
似乎您忘记设置行高了,当网格中只有一行时,默认行高将被设置为屏幕的高度。
解决方案:
设置行的高度。请参考以下代码:
<Grid>
<Grid.RowDefinitions>
<RowDefinition Height="Auto"/>
</Grid.RowDefinitions>
<Grid.ColumnDefinitions>
<ColumnDefinition Width="Auto"/>
<ColumnDefinition Width="*"/>
</Grid.ColumnDefinitions>
<!-- vessel label and button -->
<Label StyleClass="headerSub" Grid.Column="0" x:Name="currentVesselLabel"
Text="huidig voertuig:" VerticalTextAlignment="Center" HeightRequest="60"/>
<Button Grid.Column="1" Text="selecteer voertuig"
BindingContext="{x:Reference currentVesselLabel}"
HeightRequest="{Binding Path=HeightRequest}"
ClassId="selectVesselButton" x:Name="selectVesselButton"/>
</Grid>
