Xamarin Xaml Bind height of button to height of Label - xaml

Question

I got a label and a button next to each other in a grid. I'm trying to get the button to match its Height with the Label.
current 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>
I tried setting the BindingContext to the label and bind the HeightRequest property of the button to the Label's Height and HeightRequest property. However, both don't work. How do I bind the height of the button to the height of the Label?

Answer 1

Cause:
It seems that you forgot to set the height of row.When there is only one row in the grid.The default height of row will be set as the height of screen.
Solution:
Set the height of the row.Refer to the following code:
<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>
