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’ve just published XAML Power Toys 4.0 here:
http://karlshifflett.wordpress.com/2009/02/10/xaml-power-toys-40-released-code-name-mvvm/[^]
New Features
• Extract properties to a Style allows selecting a control, choosing desired properties and have those selected properties extracted to a newly created style
• Create ViewModel Class from a VB.NET or C# code window. Easily create a ViewModel stub that includes commands and exposed data class.
• Group into GroupBox
• Option to generate x:Name for controls
• Option to add ForeReRead converter to TextBox bindings (both VB.NET & C# converters included in source and binary downloads. Converter is also included in the OceanFramework.WPF namespace.)
• Option to add TargetNullValue to TextBox.Text bindings when Source property is Nullable
• Corrected secondary application domain load issue reported by DevExpress. This fix also solves another edge case secondary application domain load issue.

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
Mark

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).

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??

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,
Does anybody know if VS2008 has an internal web browser, for launching Silverlight apps ? I believed have seen screenshots with that...

No. I dont think VS 2008 has an internal web browser. not even in VS2010.. 
|
|
|
|
|
That's not true : there is one.
* Right click a page (.aspx, or on a folder)
* Select Browse With...
* Choose your browser : internal
* Click Set as Default
* Click Browse

Working through this... just completed part 3.
Accessing the ASP.NET Authentication, Profile and Role Service in Silverlight[^]
I can't get the images to appear in Firefox but I can in IE and Google Chrome - despite the fact that the latter is not "officially" supported. ???
Any ideas for things to tweak in Firefox?
Update: It now works as of this morning - no code changes. Must have been a caching issue.

It should work in Firefox as well.
Are you using that sample or did you change something in that sample?

It works now (tried again this morning) so must have been a caching problem.

Can any one tell me, if I need to populate the items of a Panel dynamically using Binding, how can I do so?
A panel has got a Children property, unlike other collection control ListView, Listbox that offers a property named ItemsSource or stuffs like that. How can i make this thing work for a panel.
To clarify the question- How to bind the items displayed inside a FishEyePanel ..or is it possible at all?
usually, What I can do is
<stackpanel>
however, I want to generate the number of button using Binding...is it possible?
