RE: [OzSilverlight] SL Fonts.?
Muhammad,
I'm not sure you could get that info directly from SL, but you can look for the
appropriate function in JS and call it from SL.
If you depend on a certain font you can include them in a zip file and get them
through a request and create a FontSource object using the stream. This is part
of SL docs
Downloading Fonts
Silverlight does not include any fonts in its installation package. If you want
to use a font for a TextBlock or TextBox element that is not on the list of
supported local fonts, you can specify the font in XAML by using the FontFamily
property, or in code using the FontSource property. The FontFamily property can
specify a single font file or a zip file containing font files. In either case,
the file must be embedded in a DLL as a resource. When using FontSource, your
code can load the font (or zip of fonts) from a stream such as isolated
storage.

It can be done in WPF but the same class doesn't seem to exist in
Silverlight
eg. Here is an example
Window.Resources
DataTemplate x:Key=FontTemplate
StackPanel Orientation=Horizontal
Border BorderThickness=1 BorderBrush=Black Margin=10
TextBlock FontFamily={Binding Source}
Text=Sample Text Margin=5 /
/Border
TextBlock Text={Binding Source} VerticalAlignment=Center /
/StackPanel
/DataTemplate
/Window.Resources
ListBox x:Name=fonts ItemTemplate={StaticResource FontTemplate} /
And in code :
fonts.ItemsSource = System.Windows.Media.Fonts.SystemFontFamilies;

RE: [OzSilverlight] SL Combobox problem.?
The ObservableCollection (or any collection that implements
ICollectionChange) exposes an event (CollectionChanged) and the Databinding
will subscribe to this to monitor changes in the collection, when one occur
it will cause the control to refresh it's datasource.
This is similar to objects that implement INotifyPropertyChange, those will
expose a PropertyChanged event that will trigger an update in the UI
whenever the control value of the property changed (or more precisely when
the event is fired)

Subject: [OzSilverlight] SL Combobox problem.?
Hi All,
I have a Combobox in SL App when I remove item from the collection
(ObservableCollectionUserDTO/List UserDTO ) work fine, but the issue
that Combobox not update its items-Containing area when its bind with
ObservableCollection, mean if there were 4 items in Combobox then will
remain 3 but total space of items-Containing remain 4. And but when its bind
to List then it only delete the item from collection but not from Combobox
area, mean if there were 4 items in Combobox then will remain even 4.
why, here is some code:
XAML:
ComboBox x:Name=ddlUser Canvas.ZIndex=2 Grid.Row=0 Grid.Column=1
DisplayMemberPath=name
ToolTipService.ToolTip=Select user.
Style={StaticResource NormalDropDownListStyle} /
CS:
private ObservableCollectionUserDTO resultUserDTO = new
ObservableCollectionUserDTO();
private ListUserDTO resultUserDTO = new ListUserDTO();
also why should I use List over ObservableCollection.?
Enen though I call this like,
ddlUser.UpdateLayout();
ddlUser.SelectedItem = innerUserDTO;

RE: [OzSilverlight] SL Combobox SelectedItem ?
The ComboBox inherits from selector, which is also the baseclass for the
ListBox so the way you use it will be really similar.
You can use any collection or to be more specific any IEnumerableT
If you want you can define a datatemplate to personalize the way each object
will look or go with the default template that will display the ToString of
each object in the collection.

Subject: RE: [OzSilverlight] SL Combobox SelectedItem ?
Make sure that the object is already in the ItemsSource. The combo can only
select items that are part of the collection they're bound to.
ddl.DataContext = MyCollection; // or
dll.ItemsSource
ddl.SelectedItem = new MyClass(); // Won't work
because MyClass is not part of the collection
ddl.SelectedItem = MyCollection[0]; // J
The order is also important so this won't work either.
ddl.SelectedItem = MyCollection[0]; // J
ddl.DataContext = MyCollection; // or
dll.ItemsSource
Similarly in XAML if you're databinding the properties
Combo SelectedItem={Binding SomeProperty}
DataContext={Binding SomeCollection}/
This won't work because it will try to get the SelectedItem first and then
bind the items, just as in the previous C# example
This will do the trick
Combo DataContext={Binding SomeCollection}
SelectedItem={Binding SomeProperty} /

RE: [OzSilverlight] XAP File.?
I know, that's great, but it's only for simple properties.
customersList.DataContext =
Kernel.GetICustomerDataAccess().GetCustomerByCountry(Mexico);
or even in the properties window
Background = {StaticResource SomeResource}
It would also be nice to have an option Select by Click like in IE Toolbar.
Something equivalent is to use the Event Monitor and then double click the
event that catched something, but it's far from ideal since many objects
might not trigger events or it could get to noisy.

An area of the Silverlight ecosystem that I think will be interesting to see is the third-party offerings. It will be interesting watching how many third party controls arrive for Silverlight, as well as what types of controls they are, and how the market reacts to them. I know that in the WPF space, we'd see a lot less WPF LOB applications if it weren't for the likes of Infragistics, Xceed, ActiPro and Syncfusion. As much as there are many concepts that carry between WPF and SL, many of the implementation details that control vendors rely on don't seem to cross over so easily, which makes it harder for third parties to build on top. Examples off the top of my head: custom markup extensions, template binding for attached (read: third party extension) properties and the lack of a logical tree (a lot harder to use binding with non-visual elements). Certainly there are vendors building on Silverlight, but their offerings seem tamer than their WPF counterparts, and I suspect that's a limitation imposed by some of the missing areas of extensibility above. But then again, will third party controls even be relevant for Silverlight applications? Is there a thriving market for third party Flash controls?

Also, showing designers just how many great C# developers are out there to take away their ActionScript/Flex pain so they can concentrate on designs and not program implementation will help attract more designers. I'd put money on there being more C# developers out there than Action Script developers - and that on average the C# developer has more experience (i.e. they are *better* :)). We are starting a new user group called the Silverlight Designer and Developer Network in Melbourne (first meeting Nov 27th - a formal announcement coming soon) especially to help bridge this gap... My observation is that traditionally designers don't have a lot of SIG/community stuff they attend regularly - hopefully the SDDN can buck that trend. Each meeting will have content for designers and content for developers - including lots of content on bridging the gap between the two camps.

RE: [OzSilverlight] Success or Failure of SL.?
I agree that the big number of C# developers will favour SL adoption as the main RIA platform, but remember than that's only one of many languages supported by .NET and thus Silverlight, being VB de most used, but I don’t like it, so let's not talk about it. The DLR will be a huge bump for .NET adoption from other developers, specially from the Ruby and Python communities. For them, SL is a great opportunity to offer a richer experience than AJAX (we're still not there), coding in their own languages and easily sharing business logic, validations, data, etc. I remember a talk at TechED, I don’t remember the name of the guy, but he was talking about IronPython and told us (paraphrasing), you’re not the target of these (or the other DRL languages), if you’re happy coding on C#, MS will be happy, but our real target is the Python community. So as a Python, Ruby or even JavaScript developer, what would you choose as a RIA platform having the DLR? Tooling and integration, and even the languages are not totally there yet, but I was recently looking at a project called Silverline http://github.com/jschementi/silverline/tree/2642bc5b3709565a4037a8d38e7f97b185bbd505 , part of the IronRuby-Contrib project, that will help as a bridge for Rails Devs to SL. Sounds really compelling. Silverline also lets you run pieces of your Rails application on the client, removing the need to write a separate JavaScript or Flash application simply to move functionality to the client. This is accomplished by flagging certain actions as client, and running the necessary pieces of your Rails appliation and Rails itself on IronRuby in the browser. Miguel A.

To build only the Silverlight 2 version type: build platform-silverlight20 If you've installed Silverlight 2 RC0 this will yield the following message: [echo] Silverlight v2.0 is not available. Skipping platform. The problem is how the NAnt Silverlight Build tasks detects if Silverlight is installed or not. It looks for a hard-coded path at C:\program files\Microsoft Silverlight\2.0.30523.8 - Which is the location of Beta 2.0. If you've upgraded you don't have this path anymore. The easiest fix is to create this folder, and copy the content from the RC0 folder (2.0.30923.0) into the Beta 2 folder (2.0.30523.8). That way you can trick the NAnt build task and get it to build against RC0. The real fix off course is to re-build NAnt with this fix, and update the compiled version of NAnt under your Ninject folder structure.

In that if a user is authenticated and you have all the forms for example housed in the .XAP (which is fine), then before you accept and receive data between the client and server you need to sanitize it and ensure the user doesnt go rogue. Its something at times Ive seen folks in both Flash and Silverlight space overlook (as once they get through the security gate, its an assumed the user will not interfere with the client). It can be small things like switching parts of the UI on or off and the more clues you give a malicious user, the more they have to work with in terms of figuring out what it is you have written and how you expect data to be sent back and forth. Its more of a cautionary tip and Id highly recommend folks (when it comes to Admin vs. Public) look into dynamically loading .XAP files or more to the point bring XAML in over the wire as well. Ive gotten loading of modules to work dynamically and should post some demo code around this as its quite cool to bring in .XAP files over the wire as needed. As when you load a .XAP file, it stores it local cache (ie not in memory) and then feeds from it when it needs it as well, so the tax isnt high. You also can do sniff tests to determine if an assembly is loaded or not and if it isnt go get it. Ive taken a framework I wrote in the early days of Flex and ported it over to Silverlight, (SynergyFlex = SynergyLight) :D and as we draw closer to Silverlight 2 ship dates Ill see if I can spare up some time to release it as a basic starter guide to some of these ideas.

Even if you fake the response and trick your Silverlight app (which would be easy, just download the XAP, unzip it, and have it talk to a different end-point), your XAML shouldn't really contain any secret information anyway. Your users is not part of your markup, that's just data. That information should be sent to the user in an authenticated WCF call So even if you manage to enable the show all user screen, your service should re-validate on the server side before giving you that data. But there might be cases where what you describe makes allot of sense. And partial loading of XAP's is quite interesting stuff - could be useful for things like composite Silverlight applications, where you download modules as needed.

You can build a FrontController class which marries both the Event and Command together today. Given that Silverlight has RoutedEvents, one could simply throw an Event (through a homemade EventDispatcher), the FrontController catches it and marries the event with a command and then the command fires a execute method. This in turn will carry out the workflow required in order to achieve a successful command delivery. Upon a result, the command can also throw another command (depending on the data returned) and so on. This is good, as it essentially allows again multiple events to feed off the same commands (but yet have different semantic value) whilst at the same time keeping parts of the overall view abstracted from one another.

While using the Model-View-ViewModel pattern you have all your UI state and behavior in a separate class. This class is normally set as the data context on your View (XAML page), and you bind everything against this class. Even things like IsSaveEnabled to enable the save button. The View communicates back to the ViewModel by commands. The benefit is that you don't have any btnSave_Click event handler in your codebehind. Instead your ViewModel waits for that Command to trigger, and then do the work. The benefit of designing your application using these patterns is that you can build quite big applications with (almost) no code-behind. This makes your app easier to test, more maintainable, and easier to work with for a designer using Blend. So what is the problem? The problem is that there is no declarative(XAML) way of triggering animations when thing happens. So if you want to start a storyboard then the ViewModel IsBussy property is true, you will have to write this code by hand. Typically that would involve listening to a PropertyChanged event in the codebehind of the form, and when the ViewModel IsBussy changes to true, then start the storyboard, when it changes to false, then stop it. This isn't the end of the world, but when we're so close to achieving no-code behind it would be nice to go all the way. Also, doing this forces your designer to have a stroyboard with that exact name (say ShowProgressanimation) present, so you as the developer ends up owning part of the user experience. If the designer accidentally deletes the storyboard the app will fail at runtime, or perhaps not even compile. The less named elements in your XAML file the better. - Jonas On Fri, Sep 19, 2008 at 1:12 PM, Barry Beattie [EMAIL PROTECTED] wrote: It's a PITA to make apps with all the bells and whistles in XAML then have to break M-V-VM to finish it off. got an example to show what you mean?
