Ironruby core - Apr 2008 - Manipulating Silverlight controls dynamically from IronRuby - is it currently possible ?

Hi,

Is it currently possible to add children to an existing Silverlight control
from the ruby code side ? (like in the IronPython version seen on
http://www.voidspace.org.uk/ironpython/webide/webide.html - great stuff btw
Michael!)

And an extra question: is the Button control available from the silverlight
build on http://dynamicsilverlight.net ?

cheers,

-- Thibaut

Hi

Yes the button control is available. The code that goes with that blog post
uses a button. I want to improve that code still because you can do more
with IronRuby than that. I just need some time to do it.

Basically you need to add the assemblies System.Windows.Controls and
System.Windows.Controls.Extended to your app folder. You can find those
assemblies in program files\microsoft sdks\Silverlight\v2.0
You also need to add a AppManifest.xaml file to your app folder and that
should contain:
<Deployment
xmlns="http://schemas.microsoft.com/client/2007/deployment"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
RuntimeVersion="2.0.30226.00"
EntryPointAssembly="Microsoft.Scripting.Silverlight"
EntryPointType="Microsoft.Scripting.Silverlight.DynamicApplication">
  <Deployment.Parts>
    <!-- Add additional assemblies here -->
    <AssemblyPart Name="Microsoft.Scripting.Silverlight"
Source="Microsoft.Scripting.Silverlight.dll" />
    <AssemblyPart Source="Microsoft.Scripting.dll" />
        <!-- Silverlight SDK controls assemblies -->
        <AssemblyPart Source="System.Windows.Controls.dll" />
        <AssemblyPart Source="System.Windows.Controls.Extended.dll"
/>
        <AssemblyPart Source="System.Xml.Linq.dll" />
        <AssemblyPart Source="IronRuby.dll" />
    <AssemblyPart Source="IronRuby.Libraries.dll" />

    </Deployment.Parts>
</Deployment>

from then on you can use the button control but you still need to add the
namespace to your xaml file. I have this for a button.
<UserControl x:Class="System.Windows.Controls.UserControl"
    xmlns="http://schemas.microsoft.com/client/2007"
    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"

xmlns:c="clr-namespace:System.Windows.Controls;assembly=System.Windows.Controls"

xmlns:e="clr-namespace:System.Windows.Controls;assembly=System.Windows.Controls.Extended"
>
<Grid>
<e:WatermarkedTextBox x:Name="search_textbox" 
Watermark="Topic..."
FontFamily="Trebuchet MS" Grid.Column="1"
FontSize="12" Padding="1,3,1,1" />
<c:Button Content="Search" x:Name="search_button"
Style="{StaticResource
SearchButton}" />
</Grid>

Hey Thibaut, sorry for the very delayed response ...

Every Silverlight object you place on a page is sandboxed, so other Silverlight
objects cannot access each other. So a Silverlight greasemonkey-esk thing
isn''t really possible. =( When you create a Silverlight object, you
implicitly say whether you want to use the Silverlight 1 or Silverlight 2
behavior with the ''source'' attribute; when you give it a XAML
file:

<params source=''foo.xaml'' />

You''re saying you want to use Silverlight 1, which bypasses the CLR and
gives you JavaScript programmability of the Silverlight visual elements.
However, when you give it a xap file:

<params source="foo.xap" />

You''re saying you want to use Silverlight 2, which gives you Ruby,
Python, C#, etc. Unfortunately, there''s no way to combine these
"modes", so you can have native JavaScript and .NET languages both
manipulating the Silverlight control. However, if you''re just using
HTML, you *can* use Ruby to monkey-patch the page. =)

Hope that answers your questions,
~Jimmy
