How to dynamically add buttons and Silverlight player in a Grid? - silverlight

Question

I'm basically trying to create the following set of code dynamically/programmatically but I'm unsure of how to do it.
<Grid x:Name="LayoutRoot">
<Grid.RowDefinitions>
<RowDefinition Height="Auto"/>
<RowDefinition Height="Auto"/>
<RowDefinition/>
</Grid.RowDefinitions>
<smf:SMFPlayer x:Name="player" Grid.Row="0" AutoPlay="False">
<smf:SMFPlayer.Playlist>
<media:PlaylistItem
DeliveryMethod="AdaptiveStreaming"
MediaSource="http://video3.smoothhd.com.edgesuite.net/ondemand/Big%20Buck%20Bunny%20Adaptive.ism/Manifest"/>
<media:PlaylistItem
DeliveryMethod="AdaptiveStreaming"
SelectedCaptionStreamName="textstream_eng"
MediaSource="http://streams.smooth.vertigo.com/elephantsdream/Elephants_Dream_1024-h264-st-aac.ism/manifest"/>
</smf:SMFPlayer.Playlist>
</smf:SMFPlayer>
<StackPanel Grid.Row="1" Orientation="Horizontal" Background="Transparent">
<Button x:Name="test1" Height="30" Width="70" Content="Test 1"/>
<Button x:Name="test2" Height="30" Width="70" Content="Test 2"/>
</StackPanel>
</Grid>
Here's how it looks statically:

Answer 1

First of all, you must give a name to your StackPanel like this;
<StackPanel x:Name="spBottom" Grid.Row="1" Orientation="Horizontal" Background="Transparent">
<Button x:Name="test1" Height="30" Width="70" Content="Test 1"/>
<Button x:Name="test2" Height="30" Width="70" Content="Test 2"/>
</StackPanel>
And then, you must add the following lines in code-behind;
For iLoop As Integer = 0 to 4
Dim btn As New Button With {.Content = "Button" & iLoop}
spBottom.Children.Add(btn)
Next iLoop
I hope this will be help to you!

Answer 2

The controls without an xmlns (XML namespace) prefix can be created in your code-behind without adding any usings. For example, in C# you can recreate the StackPanel from your XAML using the following code:
StackPanel panel = new StackPanel() { Orientation = Orientation.Horizontal, Background = null };
panel.SetValue(Grid.RowProperty, 2);
LayoutRoot.Children.Add(panel);
The elements with an xmlns prefix, anything with a colon, such as <smf: require knowledge of the namespace in the codebehind. The associated namespaces are defined in the first element and look like xmlns:smf="PathToTheNamespace". This namespace is often refrenced in a codebehind file in C# by adding a using PathToTheNamespace statement at the top.
