실버라이트 무인설치[수정]

Programming/Silverlight 2009/06/22 09:26

※스위치를 잘못 썼네요. -(대시)가 아니라 /(슬래시)에요;

흔히 마이크로소프트에서 배포하는 설치파일은 무인설치(Unattended installation) 라고 해서 설치 화면을 보여주지 않고 설치할 수 있는 옵션을 제공하죠.

실버라이트 설치 파일도 마찬가지에요. 방법은 아주 심플. 커맨드 프롬프트에서 실버라이트 설치 파일이 있는 디렉터리로 이동한 후 다음 커맨드를 입력하면 돼요.

  • 설치
    Silverlight.3.0.exe /q
  • 제거
    Silverlight.3.0.exe /qu

참 쉽죠? :p

참고로 당연하겠지만 윈도 비스타 이상에서는 삭제나 설치할 때 UAC가 뜨게 되죠.

어디다 쓰냐고요? 물론 웹으로만 배포할 경우에는 별로 쓸모 없겠지만 엔터프라이즈 솔루션의 경우 실버라이트 애플리케이션이 솔루션의 일부로 포함될 수도 있겠죠. 이럴 때 한꺼번에 배포한다면 편리할 거에요.

Behaviors make me depressed.

Programming/Silverlight 2009/06/11 13:18
I posted how to use DataBinding with Behaviors in Silverlight 3 recently. However, it turns out, it's impossible or very limitted.

Follow code is what I expected to work.

<Grid x:Name="LayoutRoot" Background="White">
    <Button Content="Test" HorizontalAlignment="Right">
        <i:Interaction.Triggers>
            <i:EventTrigger EventName="Click">
                <hi:ShowMessageBoxAction x:Name="Action1"/>
            </i:EventTrigger>
        </i:Interaction.Triggers> 

        <i:Interaction.Behaviors>
            <hi:BindingProxyBehavior
                        TargetName="Action1"
                        TargetPropertyName="Message"
                        Binding="{Binding Path=MockString}" />
        </i:Interaction.Behaviors>
    </Button>
</Grid>

[It doesn't work, 'cause Behaviors are not FrameworkElements]

- ShowMessageBoxAction which named "Action1" by x:Name attribute has a property named Message.
- BindingProxyBehavior is a Behavior. And it figures out "Action1" by AssociatedObject(LayoutRoot).FindName method when it has been invoked.

But It's impossible, 'cause Behaviors are not Frameworks so they can't be found by FrameworkElement.FindName method.

It's OK, I can understand why is it impossible. However how do you think about code follow:

<DataTemplate x:Key="DataTemplate1">
    <Grid>
        <Button HorizontalAlignment="Left" Content="{Binding Mode=OneWay, Path=Title}">
            <i:Interaction.Triggers>
                <i:EventTrigger x:Name="Trriger1" EventName="Click">
                    <hi:ShowMessageBoxAction x:Name="ShowMessageAction"/>
                </i:EventTrigger>
            </i:Interaction.Triggers>           

            <i:Interaction.Behaviors>
                <hi:BindingProxyBehavior
                    TargetName="ShowMessageAction"
                    TargetPropertyName="Message"
                    Binding="{Binding Path=Description}" />
            </i:Interaction.Behaviors>
        </Button>
    </Grid>
</DataTemplate>

[Does it work or not?]

It's similar to first one, except root Grid is in the DataTemplate.
Guess what? it works. Very well.
HOW COME!? Isn't it wierd?

Now I have to give up to do DataBinding with Behaviors in Silverlight 3 by that way.
It makes me depressed. "No binding, more work".
Anyway all I really want to ask Microsoft is, just allow us DataBinding with Behaviors, so we can create application rapidly, design-friendly, and even elegantly! Like follow code:

<Grid x:Name="LayoutRoot">
    <Button Content="Test">
        <i:Interaction.Triggers>
            <i:EventTrigger EventName="Click">
                <hi:ShowMessageBoxAction
                    x:Name="Action1"
                    Message="{Binding Path=Description}" />
            </i:EventTrigger>
        </i:Interaction.Triggers>
    </Button>
</Grid>

DataBinding with Behaviors in SL3

Programming/Silverlight 2009/06/09 17:43
Because Behaviors are not FrameworkElements, you can't use DataBinding with Behaviors. I posted this about it before.

<Button Content="Description">
    <i:Interaction.Triggers>
        <i:EventTrigger EventName="Click">
            <local:ShowMessageBoxAction Message="{Binding Description}" />
        </i:EventTrigger>
    </i:Interaction.Triggers>
</Button>
[You can't use DataBinding with Behaviors like above]

Well, I'm still thinking about that it's the best way to use DataBinding with Behaviors. Why I can't do like that! However, if you really want to mix up DataBinding and Behaviors just like me, there are some work-arounds.

First, you can attach a 'Binder' class to FrameworkElement as an AttachedProperty. Morten Nielsen writed such a cool class, 'SurrogateBinder' which is general data binding helper. It could be attached to any FrameworkElement, and it passes through the value which from data source to actual target. Here's sample code:

<TextBox RenderTransformOrigin="0.5,0.5"
        Text="Hello Universe!"
        binders:SurrogateBind.Value="{Binding Path=MoreValues.Heading}" 
        binders:SurrogateBind.Target="RenderTransform.Children.Item[1].Angle" >
    <TextBox.RenderTransform>
        <TransformGroup>
            <ScaleTransform />
            <RotateTransform />
        </TransformGroup>
    </TextBox.RenderTransform>
</TextBox>

It works well with any property of FrameworkElement but not for AttachedProperty like Behaviors. So you must modify little bit to targeting AttachedProperty. Also SurrogateBinder can't be set on Blend, so most of designers might not want to use it. Blend-support is important for XAML design. So I don't prefer in-line AttachedProperty as a solution, even though it is cool & smart.

Second, Pete Blois who is a program manager of Expression Blend introduced this article to show how Binding property could be used with Blend for binding to non-FrameworkElement, like Behaviors. As you know, we can't use DataBinding to properties on Behaviors, 'cause Behavior is not a FrameworkElement. But Blend seems to allow DataBinding to a property which is type of Binding. Hey! it's so tricky isn't it? :(

<i:Interaction.Behaviors>
    <id:DataStateBehavior Binding='{Binding IsOnline}' Value='True'/>
</i:Interaction.Behaviors>
[You can use DataBinding only on a property which is type of Binding. Could you guess that?]

It looks much cooler than other, but it's not a general solution. Imagine that you want to bind to 3rd party's Behavior, you nerver can do, of course it might has no Binding property! However, sample is just sample and actually it's not only for DataBinding with Behavior but also for Trigger which is raised by condition of data.

Thrid. Now, here's my approach.

<i:Interaction.Triggers>
    <i:EventTrigger EventName="Click">
        <hi:ShowMessageBoxAction x:Name="ShowMessageAction"/>
    </i:EventTrigger>
</i:Interaction.Triggers>
<i:Interaction.Behaviors>
    <hi:BindingProxyBehavior
        TargetName="ShowMessageAction"
        TargetPropertyName="Message"
        Binding="{Binding Path=Description}" />
</i:Interaction.Behaviors>


Sigh, looks messy huh? But it based on standard Behavior, so it works well with Blend and you don't need to worry about writing these XAML code. Blend will generate XAML code as well as you write.
'BindingProxyBehavior' implements Behavior class, and it exposes  some properties which are needed to determine DataBinding & binding target. It focuses only one binding per an instance, but you can attach multiple instance of it, 'cause it's a standard Behavior.

Here's sample project. Enjoy it :)

Actually I'dont like any of them, but first code-block which is impossible currently. So I really want to say, why not with DataBinding? Please?
