可以以编程方式将用户控件添加到Silverlight网格列？

<Grid x:Name="LayoutRoot">
    <Grid.ColumnDefinitions>
       <ColumnDefinition Width="100" />
       <ColumnDefinition Width="*" />
    </Grid.ColumnDefinitions>
    <Grid.RowDefinitions>
        <RowDefinition Height="Auto" />
        <RowDefinition Height="*" />
    </Grid.RowDefinitions>
   <local:MyUserControl x:Name="MyControl" Grid.Column="1" Grid.Row="1" />
</Grid>

MyUserControl myControl = new MyUserControl();
Grid.SetColumn(myControl, 1);
Grid.SetRow(myControl, 1);
LayoutRoot.Children.Add(myControl);
