How to add a grid inside a Scroll viewer programma

问题:

My XAML looks like this

<navigation:Page x:Class="SilverlightApplication1.Home">

    <Grid x:Name="LayoutRoot">
    <!--
    <ScrollViewer>
        <Grid>
            <TextBlock Text="myTextBlock" />
        </Grid>
    </ScrollViewer>
    -->
</Grid>

I want to programmatically do the commented part above via code behind.

And my code behind looks like this

public partial class Home : Page
{
    public Home()
    {
        InitializeComponent();

        ScrollViewer sv = new ScrollViewer();
        Grid grid = new Grid();
        TextBlock block = new TextBlock();

        block.Text = "My Text block";
        grid.Children.Add(block);

        sv.ScrollIntoView(grid);
        LayoutRoot.Children.Add(sv);

    }

This doesnt work, since it only shows the scroll viewer but the text block is hidden.

What is that I'm missing?

Is there a way to add children to the "ScrollViewer" control programmatically w/o using the extension method "ScrollIntoView" available in the silverlight toolkit? i didnt find a property called "Children" for ScrollViewer element

Thanks for the help

You didn't specify the ScrollViewer's content, just do this before the last line. Also you can remove the ScrollIntoView method.

sv.Content = grid;

Hope it helps. :)
