Silverlight.FX and Silverlight Store Sample App

This looks cool!!

Great as always

Good example, I was clone the same Flex Store in WPF with little bit more functionalities, as yours. It seems a greate project.
Hope that in future we have a powerful framework for Silverlight Applications.

Just a 'recommendation' - but your framework with it's behaviors, etc... seems to fill a gap in the Prism framework.

Any chance you'd consider some sort of install path and setup instructions for using your framework in conjunction with Prism?

ie. they are lagging behind in 'commanding/messaging' (see Caliburn) - and yet, I think your framework has some parts that would help provide some glue here.

At this point, imo , the ability to mix and match the different frameworks would be nice :)

Thanks

Awesome!
When I demo these sorts of websites in a corporate environment I often hear 'that is unnecessary'... the store is very usable, and the population is really getting in touch with technology. There is a perception that they take longer to develop then traditional win forms looking apps, when the reality is they should be faster.
What I like about this project is the framework for building effects. I envision that it could work just like jQuery, where we could browse and download pre-rolled effects. This could help with productivity :)

How could you make this demo even better?
Integration with windows workflow
Validation controls/pattern

Cheers

I agree to the jQuery analogy, this library is fantastic.

It would be nice to create a Silverlight.FX repository Nikhil, where others can contribute effects to the project, perhaps a Silverlight.FX Contrib :)

This i sgreat. Vey good usability and most importantly speed. For a Intranet app, something like this is superior to a standard website. Of course this app is a "store" and that does not say "Intranet" so perhaps the next example can be a "corporate intranet app"?

Why SL3? Atm, Silverlight platform is great for presentation of data, but data entry support seems to be lacking.

Wish I could be more involved with steering Silverlight.FX... I implemented the framework at my last place of work, but moved to a new role recently where I'm developing an Asp.net MVC web app with Ajax/jQuery... the web app is targetting the Apple iPhone, if the iPhone was a supported platform, then I'd be on board :) We have a requirement for duplex Wcf, so Silverlight would be a buy there. Atm we're using the Comet paradigm to simulate two-way connections.

I've read that MS plans to support SL on any platform that has an sdk? A little more light on this subject would be great.

This Looks Really cool

I'm giving it a try. Looks really handy so far.

I have an issue that you may be able to help me on.

I have created a view, and assign a viewmodel to it.

On this view I have couple of TemplatePanel.

On those Template I have couple of controls binded to some of my ViewModel properties.

For regular controls it all works wel... The get of my modelview properties are called.

If I try to use a more complex control like the Tree view from the tool kit or the Tree view from telerik. the get method of the binded property is neger called :(....

Any idea on this?

Here is a code snippet:

<fxui:TemplatePanel Style="{StaticResource sectionStyle}" Grid.Column="1" Grid.Row="2" Grid.RowSpan="3">
<TextBlock Text="{Binding Catalogentries}" fxui:TemplatePanel.ContentName="header"/> <!-- Works! Get_NavigationEntries is called -->
<telerikNavigation:RadTreeView x:Name="trvCatalog" ItemsSource="{Binding NavigationEntries}" SelectionMode="Single"> <!-- Nothing happen here! Get_NavigationEntries is not called -->
<telerikNavigation:RadTreeView.ItemTemplate>
<Controls:HierarchicalDataTemplate ItemsSource="{Binding CatalogEntries}">
<TextBlock Text="{Binding Name}" Tag="{Binding MethodName}"/>
</Controls:HierarchicalDataTemplate>
</telerikNavigation:RadTreeView.ItemTemplate>
</telerikNavigation:RadTreeView>
</fxui:TemplatePanel>

Find out where the problem was coming from.

I had not specified any fxui:TemplatePanel.ContentName="body" on the treeview. so the control was not rendered...

I will keep investigate the framework but I'm starting to really enjoy it. :)

thankx

I found SilverlightFX a great framework that simplifies application development and helps for writing much cleaner code/markup.
One thing I miss, however, is the lack of documentation. The only way I can learn about the framework is from the blog posts and the provided samples and sources. Yes, that is quite a lot actually, but still not enough to get a deeper understandings. Learning the things this way is also a time-consuming task. As a suggestions a would recommend writing a documentation that explains how the different parts of the framework can be used.

I currently use SilverlightFX in an on-going Silverlight project and it really adds a great baseline you can build on.
One thing I struggled with is the ShowForm action. I digg into how it is used in the AmazonStore sample and it is quite straight forward, but I couldn't get it running. Basically what I have is exactly the same as in the AmazonStore sample:
<TextBlock ...>
<fxui:Interaction.Triggers>
<fxui:MouseTrigger>
<fxaction:ShowForm FormType="MyForm" />
</fxui:MouseTrigger>
</fxui:Interaction.Triggers>
</TextBlock>

where MyForm(tried also with the full name) is fxui:Form with a fxui:TemplatePanel

Click on the TextBlock fires nothing. Nothing happens at all. I don't have an idea how I can debug that also.

I'll appreciate if anyone can help on that.

Thank you.

@Nikhil - about the documentation - yes, I can imagine that.

I posted another comment here on the Form issue, but I don't see it now. It may have been spam-scored or something. What I wrote in it was that once I change my app to inherit from XApplication (not from Application) the issue was gone. But I'm curious why this is happening. Is there any particular reason? Everything else I'm using from Silverlight.FX framework doesn't require that.

My Form have a parameterless public ctor. I already tried to debug it, but the debugger doesn't break on any exception (I have a reference to the debug dll). I uploaded a project that isolates my case - you might want to take a look at it. http://weblogs.asp.net/blogs/emilstoichev/SilverlightFXTests.zip
By just changing my app to inherit from XApplication the form starts working.

I'm guessing that like many Silverlight developers, I'm totally confused as to which framework to select going forward (FX, Caliburn, Prism, Ninject, or one of the dozens of samples explaining WVVM) if I'm starting out a new application with a multi-year lifespan and therefore SL3 compatibility is an important consideration.

Is it true that FX is a good choice if my requirements are (in order of importance):

- SL3 compatiblity
- small footprint
- dependency injection
- navigation
- effects
- themes (are FX themes compatible with SL Toolbox themes BTW?)

Perhaps another way of asking this is: Which framework will be most easily subsumed by SL3?

Hello,
I found a strange binding behavior in the SilverlightFX. It's maybe a bug or maybe I don't understand its philosophy well. Would you check this small application to demonstrate this behavior: http://aurum.hu/prog/SilverlightApplication1.zip
It contains two textboxes, one of them is binded to a data source class, another one is binded to a property of the model. Take a break point to the setter of the property of the model then try to append only one char to the textbox is binded to the property of the model. If you change only one char and click out from the textbox or use the TAB key, the change will be binded and set into the property. In theory, but in practise every second times only. So, if you change only one char on tht textbox, every second change will cause binding on the model. The another textbox binded to the data source class works correctly, this behavior related to the Model only. If you change two or more chars, the binding works correctly.
This image demostrates this effect: http://aurum.hu/prog/bindingerror.png The textbox contains "ModelName12" but the textblock only "ModelName1", because the second change, the "2" didn't cause binding, the value didn't set back to the property of the model.

Hello Sir,

We are a bizspark partner of Microsofts and we are developing all our sites using silverlight technology. We have some questions regarding your application. Is there a contact phone number that we could possibly use to help us integrate your amazon example with what we are doing. This would be a great help.

Thanks

Silverlight.FX Rocks!

Wouldn't it be great if your Model class inherited from DependencyObject so we could have custom DependencyProperties in the view model?

I need your help in implementing an aggregate predicate filter on the list of products so we could have multiple filter criterias (predicates).
For simplicity, lets say we want to filter by price range (with a lower price slider and an upper price slider).

How should I go about it?

I tried a couple of ways like:
1. Having multiple converters (lets say lowerPriceConverter, upperPriceConverter etc.) and binding the 2 sliders and the list to the ProductFilter. But obviously you only have access to one filter at a time, so this doesn't work.

2. So I tried adding the properties (like int lowerPriceRange, int upperPriceRange etc.) to the Main Window View Model and binding the sliders to these properties. But these bindings don't work.... probably because they are just normal CLR properties instead of DependencyProperty

3. So I created the following class (yeah its house search not product):

public sealed class HouseFilter : DependencyObject
{
public static readonly DependencyProperty HouseFilterPredicateProperty;
public static readonly DependencyProperty PriceRangeLowerProperty;
public static readonly DependencyProperty PriceRangeUpperProperty;

public IPredicate<object> HouseFilterPredicate
{
set { SetValue(HouseFilterPredicateProperty, value); }
get { return (IPredicate<object>)GetValue(HouseFilterPredicateProperty); }
}
public int PriceRangeLower
{
set { SetValue(PriceRangeLowerProperty, value); }
get { return (int)GetValue(PriceRangeLowerProperty); }
}
public int PriceRangeUpper
{
set { SetValue(PriceRangeUpperProperty, value); }
get { return (int)GetValue(PriceRangeUpperProperty); }
}

static HouseFilter()
{
HouseFilterPredicateProperty = DependencyProperty.Register("HouseFilterPredicate", typeof(IPredicate<object>), typeof(HouseFilter), null);
PriceRangeLowerProperty = DependencyProperty.Register("PriceRangeLower", typeof(int), typeof(HouseFilter), new PropertyMetadata(0, new PropertyChangedCallback(OnFilterChanged)));
PriceRangeUpperProperty = DependencyProperty.Register("PriceRangeUpper", typeof(int), typeof(HouseFilter), new PropertyMetadata(300000, new PropertyChangedCallback(OnFilterChanged)));
}

public HouseFilter()
{
}

private static void OnFilterChanged(DependencyObject d, DependencyPropertyChangedEventArgs e)
{
HouseFilter h = (HouseFilter)d;
h.HouseFilterPredicate = new FilterPredicate(h.PriceRangeLower, h.PriceRangeUpper);
}

public class FilterPredicate : IPredicate<object>
{
private int PriceRangeLower;
private int PriceRangeUpper;

public FilterPredicate(int priceRangeLower, int priceRangeUpper)
{
PriceRangeLower = priceRangeLower;
PriceRangeUpper = priceRangeUpper;
}

public bool Filter(object item)
{
return ((House)item).Price >= PriceRangeLower && ((House)item).Price <= PriceRangeUpper;
}
}
}

The ViewModel has an instance of this HouseFilter class (called AggregateHouseFilter) and the Xaml sliders and List bind to AggregateHouseFilter.PriceRangeLower, AggregateHouseFilter.PriceRangeUpper and AggregateHouseFilter.HouseFilterPredicate

Everything works except that the List binding to the AggregateHouseFilter.HouseFilterPredicate never picks up the filter change.

Xaml for slider and ListView:

<fxui:XSlider Style="{StaticResource slider}" Width="100" Minimum="0" Maximum="300000"
Value="{Binding AggregateHouseFilter.PriceRangeUpper, Mode=TwoWay}" />

<fxui:ListView Style="{StaticResource houseList}" fxui:TemplatePanel.ContentName="body" DataSource="{Binding HouseCatalog.Houses}"
ItemFilter="{Binding AggregateHouseFilter.HouseFilterPredicate}" ItemSort="{Binding HouseSort}">

Any ideas how to implement this sort of composite predicate search with Silverlight.FX?

Thanks

Hi All,

Can you please Nikhil tell me how to connect this application to my data base, please tell me whether i have to use certain function names for webservice and
from where the data is retrieved.
Im using SQL Server 2005 or 2008

Please any one who know the answer, i appreciate your help.
