Workaround for Grid.SharedSizeGroup in Silverlight

There is no Grid.SharedSizeGroup in Silverlight 4. What is your workaround for this issue?

For example: I have a DataTemplate for ListBox.ItemTemplate consisting of a grid with two columns and I'd like to have the same width for both columns and the first column needs to have auto width开发者_如何学编程.

SharedSize Grid with Silverlight - haven't tested it but looks usable.

Shared sizing is best implemented using element property bindings in Silverlight. Just make all your shared sized elements bind to the width/height of another.

EDIT: I put a quick example of what I mean together. I'm not sure what you mean by using star sizing when you said in the question you want auto sizing -

<Grid Height="400"
      Width="600"
      Background="Gray">
    <Grid.ColumnDefinitions>
        <ColumnDefinition Width="Auto" />
        <ColumnDefinition Width="Auto" />
        <ColumnDefinition Width="Auto" />
    </Grid.ColumnDefinitions>
    <Button x:Name="parent"
            Content="CHANGE ME TO ADJUST THE COLUMN SIZE"
            Grid.Column="0"
            VerticalAlignment="Stretch"
            HorizontalAlignment="Stretch"
            Background="Red" />
    <Button Width="{Binding ActualWidth, ElementName=parent}"
            Grid.Column="1"
            VerticalAlignment="Stretch"
            HorizontalAlignment="Stretch"
            Background="Blue" />
    <Button Width="{Binding ActualWidth, ElementName=parent}"
            Grid.Column="2"
            VerticalAlignment="Stretch"
            HorizontalAlignment="Stretch"
            Background="Yellow" />
</Grid>
