WinUISharedSizeGroup

This repo implements WPF's useful SharedSizeGroup and IsSharedSizeScope in WinUI, but with some difference.

Here's an example showing how to use:

with xmlns:h="using:WinUISharedSizeGroup.Helpers"

<ListView ItemsSource="{x:Bind DataCollection}" h:ColumnSharedSizeHelper.IsSharedSizeScope="True"
          Width="400" VerticalAlignment="Center">
    <ListView.ItemTemplate>
        <DataTemplate>
            <Grid ColumnDefinitions="Auto,*">
                <TextBlock Text="{Binding Name}" VerticalAlignment="Center" h:ColumnSharedSizeHelper.SharedSizeGroup="SampleGroup"/>
                <TextBox Grid.Column="1" Text="{Binding Salary}"/>
            </Grid>
        </DataTemplate>
    </ListView.ItemTemplate>
</ListView>

Difference

1. Requires the extra library Microsoft.Xaml.Behaviors.WinUI.Managed
2. Only for columns implemented in this repo, but most code can be reused for row's
3. SharedSizeGroup property is attached to the actual content rather than the ColumnDefinition, as we have no way to listen to ColumnDefinition's size change
