This[^] article is not Silverlight but it might just help you.

Its not in WPF - its in simple winform !

Use a DataTemplate for the ListViewItem, and populate it with the the items you are interested in. Obviously, these items would have to be bound items.

I am having serious problems with the inconsistency of the development environment and want to know if it is just me. Some of the symptoms during development are;
An async call will work perfectly and then return server not found.
A method that worked 5 minutes ago fails with a spurious message then works when I restart the app again. This is a waste of endless hours as I cannot trust the IDE to be consistent.
An Async/completed pair will work if I follow through the structure of the app, then the completed method does not get hit when I shortcut the path. This one is really weird!
The WCF service will not update the reference, occasionally I have to delete the service from the SL app just to get a new method to reflect into the reference
Debugging is just insane - I either need a third party app or a winforms client to debug an asynch service.
Combo boxes are a complete PITA, I am astonished we have reached release 4 and these are such a disaster.
The combination of the above means that productivity is about 10% of what I can do with winforms, even with a WCF service. I have the feeling I may have made a complete blunder recommending Silverlight.

Yes, it's just you... 
No, seriously, I have exactly the opposite problem - working with winforms is a torture for me, while SL and WPF seems to go smoothly. I guess it's just the matter of personal preference - everybody has to find at least 1 technology to hate.

*Cough*Use Attach to running process to debug - it's a lot easier.

Oh yes they are, and then we have some stellar decisions from IT, they have decided that remote sites will have to access the systems via citrix.

Intersting. We too had a similar issue with a client.
The client had to run SL apps on citrix.
Still not found a workaround.

Yeah, that happens to me a lot as well - more so in WPF, but occasionally in Silverlight as well.

I yet to create a WPF app, working with SL is slowly getting better as I start to find the gotchas. Figured out another one today, where the completed event is not being hit, it is just AFTER the other events have been completed.
I was impressed by the SL out of the browser, right click on the app in the browser and install, it copies the xbap to the local drive and it look good without the browser visual overhead.

I have two comboboxes on my view. One is for categories,and one is for subcategories belonging to categories.
So the data might look like this:
Category-
Fruit
Vegetable
SubCategory-
Apple
Orange
Carrot
So what I want is the second combobox to display only carrot when the user chooses vegetable, and apple, etc when they choose fruit.
The relationships are set up in the database and my only issue is the event driven binding. When the window loads the view model I load the categories, but not the subcategories because I don't know which ones to load until the user selects a record from a listview.
So my question is twofold:
1. From the view how do I trigger the databinding of the subcategory combobox in the event that the listbox item is changed.
2. From the view how do I trigger the databinding of the subcategory combobox in the event that the category combobox selecteditem is changed.
This is the datasource for the subcategory combobox.
public ObservableCollection<Defect> AllSubCategories { get; private set; }
private void CreateAllSubCategories(int categoryId)
{
var query = _dc.subCategories.Where(subcategory => subcategory.categoryId == categoryId);
var allDefects = query.ToList();
AllSubCategories = new ObservableCollection<SubCategory>(allSubCategories);
}

Thanks for the link, it was not exactly what I was looking for but it did lead me to a lot of interesting reading. As it turns out, all I really needed to do was invoke the OnPropertyChanged event for my Subcategory Observeable collection to update the UI after updating the Category observeablecollection selected item.

Buy a book, read some articles, read some white papers, bloody hell do some research. With that attitude (ask someone to spoon feed you) I suggest a change of career/study.

It's a client-side web application, much like Flash.

hello,
This is a question on how to escaoe "double quote" in a xaml - I tried different things suggested by here (but no luck)[^]
See below - I tried to reference a Cells["IsConfigurable"] column value but
<br />
<Style x:Key="cColumnStyle" TargetType="{x:Type igDP:CellValuePresenter}"><br />
<Setter Property="Background" Value="LightGoldenRodYellow "></Setter><br />
<Style.Triggers><br />
<DataTrigger Binding="{Binding Path=Cells["IsConfigurable"].Value}" Value="False"><br />
<Setter Property="IsEnabled" Value="False"/><br />
</DataTrigger><br />
</Style.Triggers><br />
</Style><br />
But keep getting error:
<br />
Error 2 Names and Values in a MarkupExtension cannot contain quotes. The MarkupExtension arguments ' Path=Cells["IsConfigurable"].Value}' are not valid. <br />

Try putting the above text in a single quote '.
Leave your double quotes - I've never tried that but its worth a shot.
