I have a StackPanel control in my WPF project, and it is in column 0 row 2 of a Grid. How can I autofit the StackPanel size to the size of that grid cell? Setting the StackPanel width and height to "auto" will just size it to its contents. I could explicitly set its width and height to numerical values, but I was wondering if there was a cleaner, more accurate way. Thank you.
Relevant XAML:
<Grid>
<Grid.ColumnDefinitions>
<ColumnDefinition Width="1*"/>
<ColumnDefinition Width="1*"/>
</Grid.ColumnDefinitions>
<Grid.RowDefinitions>
<RowDefinition Height="74*"/>
<RowDefinition Height="74*"/>
<RowDefinition Height="421*"/>
</Grid.RowDefinitions>
<Label Content="{StaticResource LoginWindow_Title}" Style="{StaticResource TitleH1}" Grid.ColumnSpan="2"/>
<Label Content="{StaticResource LoginWindow_Subtitle}" Style="{StaticResource TitleH2}" Grid.Row="1" Grid.ColumnSpan="2"/>
<Border BorderBrush="Black" BorderThickness="1" HorizontalAlignment="Center" Grid.Row="2" VerticalAlignment="Top">
<StackPanel HorizontalAlignment="Left" Grid.Row="2" VerticalAlignment="Top">
<Label Content="Log in"/>
</StackPanel>
</Border>
</Grid>
Your StackPanel
is not in Grid
, it`s inside Border
. So for it to take all available space you can set horizontal and vertical alignment to Stretch
both for it and its parent Border
:
<Grid>
<Grid.ColumnDefinitions>
<ColumnDefinition Width="1*"/>
<ColumnDefinition Width="1*"/>
</Grid.ColumnDefinitions>
<Grid.RowDefinitions>
<RowDefinition Height="74*"/>
<RowDefinition Height="74*"/>
<RowDefinition Height="421*"/>
</Grid.RowDefinitions>
<Border HorizontalAlignment="Stretch" VerticalAlignment="Stretch"
BorderBrush="Black" BorderThickness="1" Grid.Row="2">
<StackPanel VerticalAlignment="Stretch" HorizontalAlignment="Stretch">
<Label Content="Log in"/>
</StackPanel>
</Border>
</Grid>
Even so, like others mentioned, some other panel almost definetely will be better in this case.
