Silverlight中Grid.RowDefinitions和Grid.Row

定义5行

    <Grid.RowDefinitions>
            <RowDefinition Height="80"/>
            <RowDefinition Height="80"/>
            <RowDefinition Height="80"/>
            <RowDefinition Height="80"/>
            <RowDefinition Height="80"/>
        </Grid.RowDefinitions>

在上面5行分别放上5个button,
        <Button Grid.Row="0" Grid.Column="0" Margin="20" />
        <Button Grid.Row="1" Grid.Column="0" Margin="5 30" />

        <Button Grid.Row="4" Grid.Column="0" Margin="20" Height="40" Width="100" HorizontalAlignment="Left" />
