You can publish XBAPs to an IIS server or any other web server.
ClickOnce deployment is used to download and install the XBAP behind the scenes.

Windows Presentation Foundation XAML Browser Applications Overview[^]
Deploying a WPF Application (WPF)[^]

Silverlight uses its own stripped down .NET framework, which has implementations
for other platforms (Mac and Unix-via-mono so far).

I think WPF XBAPs are more appropriate for corporate/enterprisey networks.
The requirement for .NET 3.x+ framework makes them useless for cross platform
situations. However, if you know all your clients will have .net 3.5 and be running on Windows,
then an XBAP can make more sense since it has access to the full .NET framework, and WPF
has a much richer XAML implementation than Silverlight does.

From what I see - Silverlight can do even sockets it can allow very interactive experience. Even stock/derivative trading apps where client need to subscribe to constants/intensive price/pnl/others updates can be done with Silverlight, without requirement on .NET framework 3.x+.

I don't see any ... application for XBAP really...

Me neither.

I've never done one, but I can see where with a corporate app on a corporate network
it keeps all the deployment/update issues on the server end which is much easier than
dealing with even ClickOnce manually.

I want to create a list of hyperlink buttons, and the bulleted list should contain some images before the link.
For example
> how
> can
> i
> get
> this

So in place of ">" i need different images, how can i do that in Silverlight?

Thanks in advance,

Here's one way:

<HyperlinkButton NavigateUri="http://www.microsoft.com" TargetName="_blank" >
    <StackPanel Orientation="Horizontal">
        <Image Source="myresourceimage.png" />
        <TextBlock Text="Microsoft" />
    </StackPanel>
</HyperlinkButton>

You could also make your own custom HyperlinkButton:

Some controls transparent that shouldn't be

I've inherited some code that has a WPF UI. It was running great on Vista, but I've just installed Visual Studio 2008 on an XP machine and built and ran that application and the main window still looks okay, but the dialogs all come up completely transparent, with no borders and most of their controls missing. One of the dialogs, for instance, contains a grid, two buttons (OK, Cancel), some labels, a couple of calendar controls, a combobox and a widget in the lower right corner for sizing the dialog window. The only things that are visible are the labels, the combobox and the window sizing widget. I've discovered that if I can guess the locations of the buttons correctly, clicking on them works, so they're there. I'm not getting any exceptions at runtime, so I'm baffled. I've tried reinstalling Visual Studio, and SP1, in the hopes that some WPF dll was out of date, but to no avail. Two other clues: when I select an xaml file and view it in the designer UI, if I have the properties window open and a control selected, when I try to use one of the dropdowns in the properties window to select a color, I get very strange behavior. The dropdown portion of the control initially shows, but if I try to move down in the list, either with the mouse or keyboard, the list disappears, but each item gradually reappears as I move down through the list. So, in otherwords, parts of the Visual Studio UI are also transparent when they shouldn't be. That's why I decided to try reinstalling Visual Studio. Another piece of information: I copied the contents of the Output window in the debugger, when loading the dialog. I did this for both Vista, where everything works, and XP where it doesn't, and compared the lists of things that were loaded. The lists were identical with the exception of the PresentationFramework dlls. Vista used Aero and XP used Luna. I've thought about forcing my application to use Aero, to see if that helps. Any suggestions? Thanks!

I've seen this behaviour only once before - and it turned out to be an issue with the graphics card thinking that a drag was in effect when it wasn't. Basically, certain graphics cards allow you to treat windows as transparent when being dragged - this may be worth looking in to.

Thanks. That wouldn't explain why some of the controls (grid, some buttons) don't show up at all though, would it?

To be honest, I can't really remember all the details - just the fact that a screen went semitransparent on XP for no apparent reason.

I am writing a WPF app, and want to have the app minimise to the system tray, the only examples of how to do this involve adding a reference to System.Window.Forms, is adding this reference bad practice or accepted as needed to be done to get some functionality.

Thanks

I see no reason to treat this as a bad practice. I have done this exact thing once, and I reference Windows.Forms all the time to get the File Dialogs (I just like the old ones better).

Adding images to the listboxitems in the WPF Listbox control

Hi,

I want to asssociate a BitMap image with the ListboxItems in a WPF Listbox. But I could not find any property in the ListboxItem which can get associated with an image. I am loading the ListBox programatically and want to display images on the listboxitems dynamically.

Could anyone let me know how can i acheive this in the WPF ListBox?

Thanx in advance.

I would be tempted to do something like this:

<DataTemplate x:Key="MyTemplate">
  <Grid>
    <Grid.RowDefinitions>
      <RowDefinition/>
    </Grid.RowDefinitions>
    <Grid.ColumnDefinitions>
      <ColumnDefinition/>
      <ColumnDefinition/>
    </Grid.ColumnDefinitions>
    <Image Grid.Column=1 Width="{Binding myImage.Width}" Height="{Binding myImage.Height}" Source="{Binding myImage}" />
    <TextBlock Width="Auto" Grid.Column="1" 
      Text="{Binding MyTextItem}" />
  </Grid>
</DataTemplate>

Then, your listbox would look like this:

<ListBox Padding="3" HorizontalAlignment="Left" Width="Auto" 
  ItemTemplate="{DynamicResource MyTemplate}" 
  ItemsSource="{Binding Mode=Default, Source={StaticResource MyDataSource}}" 
  VerticalAlignment="Top" Height="Auto"/>

Hi Pete,
Thanx for the reply.
My actual requirement is to load the listbox with ToolboxItems. Each ToolboxItem has its own image which i want to associate with the listboxitem when i create a new listboxitem. I tried multiple ways of doing it programatically but unable to get the desired result.

Without using the xaml file how can i add items to the listbox programatically. One of the ways is setting the ItemsSource property to collection containing the items. I could populate a Treeview just by creating new TreeviewItems in the code and adding them to the Treeview.But the same did not happen incase of Listbox, am I missing anything?

Also, I am unable to group items within the listbox, could you please suggest how i can acheive this?

Thanx in adv.

Hi,

Also, using the DataTemplate given above I am not able to view any image on the Listboxitem. And sometime a XamlParseException is thrown at runtime, which is as follows

connot convert string in attribute 'Source' to object of type 'System.Windows.Media.ImageSource'

Any idea what am I missing? Is it that I cannot load a Bitmap image on the ListBoxItem??

Accessing template member!

I have a template and would like to access a UIElement. Because it is a template, it is not an object unless it is a static object. How can I create a static object in a template? The x:Name=”someName” are only to access inside template NOT outside. So we get an error when we try to access from a class. i.e. in constructor I can’t access someName. This also means that I cannot write a function when there is a change.
How this can be done?
Best regards
Agha

Hi,

I try to leave my control as thay are in case i maximaize my window - but i always find them in disorder in my window.

this is the xaml code ...

<StackPanel VerticalAlignment="Stretch" HorizontalAlignment="Stretch">
        <TextBox Name="Title" Text="Title" Background="Yellow" Width="Auto" HorizontalContentAlignment="Center" VerticalContentAlignment="Center" Height="30" VerticalAlignment="Top"/>
        <ListView Name="RecentReport" Width="Auto" Height="180" VerticalAlignment="Center" HorizontalContentAlignment="Center" />
        <StackPanel Height="52" Name="stackPanel1" Width="Auto" VerticalAlignment="Bottom" Background="Aqua" Orientation="Horizontal" />
    </StackPanel>

Use Ctrl+Left/Right to switch messages, Ctrl+Up/Down to switch threads, Ctrl+Shift+Left/Right to switch pages.
