Silverlight's XamlWriter! - Phenomenological Theories!

Silverlight's XamlWriter!

Hi,

Oh god!, this is my first blog post and this is the second time that I write a complete post and then IE crashes :((

nowadays we hear the sounds of the people who is looking around for a Silverlight's XamlWriter, but there's nothing!

I'm one of the guys who is contributing in Silverlight's Forums (rambler.elf) and I see so many people requested it.

I've decide to create a XamlWriter, and after about 10 hours working it's here! (no no, it's not a ideal XamlWriter, but don't worry, it's not so bad :-) )

a sample Xaml which is created at runtime by XamlWriter :

<Canvas Width="100" Height="150" Opacity="1" RenderTransformOrigin="0,0" Cursor="Default" IsHitTestVisible="True" Visibility="Visible" x:Name="test" Canvas.Left="20" Canvas.Top="0" Canvas.ZIndex="0">
<Canvas.Background>
    <RadialGradientBrush Center="0.5,0.5" GradientOrigin="0.5,0.5" RadiusX="0.5" RadiusY="0.5" SpreadMethod="Pad" MappingMode="RelativeToBoundingBox" ColorInterpolationMode="SRgbLinearInterpolation" Opacity="1">
      <GradientStop Color="#FFFFFFFF" Offset="0.5" />
      <RadialGradientBrush.Transform>
        <TransformGroup>
          <RotateTransform CenterX="0" CenterY="0" Angle="80" />
        </TransformGroup>
      </RadialGradientBrush.Transform>
    </RadialGradientBrush>
</Canvas.Background>
<Canvas.OpacityMask>
    <RadialGradientBrush Center="0.5,0.5" GradientOrigin="0.5,0.5" RadiusX="0.5" RadiusY="0.5" SpreadMethod="Pad" MappingMode="RelativeToBoundingBox" ColorInterpolationMode="SRgbLinearInterpolation" Opacity="1">
      <GradientStop Color="#FFFFFFFF" Offset="0.5" />
    </RadialGradientBrush>
</Canvas.OpacityMask>

    <Ellipse StrokeMiterLimit="10" StrokeThickness="1" StrokeStartLineCap="Flat" StrokeEndLineCap="Flat" StrokeLineJoin="Miter" StrokeDashOffset="0" StrokeDashCap="Flat" Stretch="Fill" Width="20" Height="20" Opacity="1" RenderTransformOrigin="0,0" Cursor="Default" IsHitTestVisible="True" Visibility="Visible" x:Name="el" Canvas.Left="0" Canvas.Top="0" Canvas.ZIndex="0">
      <Ellipse.Fill>
        <SolidColorBrush Color="#FF808080" Opacity="1" />
      </Ellipse.Fill>
    </Ellipse>
    <UserControl1 Width="0" Height="0" Opacity="1" RenderTransformOrigin="0,0" Cursor="Default" IsHitTestVisible="True" Visibility="Visible" Canvas.Left="0" Canvas.Top="0" Canvas.ZIndex="0" />
    <Canvas Width="0" Height="0" Opacity="1" RenderTransformOrigin="0,0" Cursor="Default" IsHitTestVisible="True" Visibility="Visible" Canvas.Left="0" Canvas.Top="0" Canvas.ZIndex="0">

        <Rectangle RadiusX="0" RadiusY="0" StrokeMiterLimit="10" StrokeThickness="1" StrokeStartLineCap="Flat" StrokeEndLineCap="Flat" StrokeLineJoin="Miter" StrokeDashOffset="0" StrokeDashCap="Flat" Stretch="Fill" Width="100" Height="100" Opacity="1" RenderTransformOrigin="0,0" Cursor="Default" IsHitTestVisible="True" Visibility="Visible" Canvas.Left="0" Canvas.Top="0" Canvas.ZIndex="0">
          <Rectangle.Fill>
            <SolidColorBrush Color="#FFFFFFFF" Opacity="1" />
          </Rectangle.Fill>
          <Rectangle.RenderTransform>
            <TransformGroup>
              <RotateTransform CenterX="0" CenterY="0" Angle="25" />
            </TransformGroup>
          </Rectangle.RenderTransform>
        </Rectangle>

    </Canvas>

<Canvas.RenderTransform>
    <TransformGroup>
      <RotateTransform CenterX="0" CenterY="0" Angle="80" />
    </TransformGroup>
</Canvas.RenderTransform>
<Canvas.Triggers>
    <EventTrigger RoutedEvent="Canvas.Loaded">
      <BeginStoryboard>
        <Storyboard>
          <DoubleAnimation From="0" To="10" AutoReverse="False" BeginTime="00:00:00" Duration="00:00:00" SpeedRatio="1" FillBehavior="HoldEnd" RepeatBehavior="00:00:00" Storyboard.TargetName="el" Storyboard.TargetProperty="Opacity" />
        </Storyboard>
      </BeginStoryboard>
    </EventTrigger>
</Canvas.Triggers>
<Canvas.Resources>
    <Storyboard AutoReverse="False" BeginTime="00:00:00" Duration="00:00:00" SpeedRatio="1" FillBehavior="HoldEnd" RepeatBehavior="00:00:00" x:Name="testSB">

        <DoubleAnimationUsingKeyFrames AutoReverse="False" BeginTime="00:00:00" Duration="00:00:00" SpeedRatio="1" FillBehavior="HoldEnd" RepeatBehavior="00:00:00">
          <DiscreteDoubleKeyFrame Value="5" KeyTime="00:00:00.5000000" />
        </DoubleAnimationUsingKeyFrames>

    </Storyboard>
</Canvas.Resources>
</Canvas>

Limitations :

WORKS WITH SILVERLIGHT 1.1 ALPHA
custom prefixes is not suported. for example : <uc:UserControl1 ... will be resolved to <UserControl1
due to silverlight's limitation for dependency properties, the ones that are not in the control's hirarechy except Canvas.Left, Canvas.Top, Canvas.ZIndex, Storyboard.TargetName and Storyboard.TargetProperty, are not supported.

Hi,

I've sent some traffic your way. Do you plan publishing a SL 2.0 version of the XamlWriter class?

Hi Justin,

Yes I've planned to rewrite the class for SL 2.0.

do you wanna help me? :-)

Thanks

Mehran,

Great work here. I am looking foward to a SL2B1 release. In the meantime, I pulled the code into a SL2B1 class and it mostly worked. I had to hardcode a "return true" on line 17 of TypeValidator.cs and I changed line 166 of XamlWriter.cs to read:

if (val != null && val.GetType().ToString() == "System.Windows.DependencyObject")

Then I am able to at least get somewhere.

Thanks and I hope that helps you a bit!

Dave

Hi Dave,

Thanks for your help. ;)

I'm experiencing busy days at office, but I'm looking forward to take my time for rewriting the class.

Thanks again.

So, how does one include namespaces?
