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.

This is in real mess. Why don't you use a Converter and do these operations there.

Is it acceptable from a MVVM standpoint to put form related (data independent) code in the code-behind file of the view?
Example:
private void RightButtonClick(object sender, RoutedEventArgs e)
{
ListBoxPreview.SelectedIndex = ListBoxPreview.SelectedIndex + 1;
}
It is an agnostic function so I think it is alright but I am curious from a clinical standpoint what you guys think.
Cheers, --EA

One of the funny things about MVVM is that people seem to get it into their heads that MVVM means no code behind the view, and that's just silly. If you want to put something in the view because it's view related, then go for it. Only the anal would criticise you.
|
|
|
|
|
Ha, the internet is where the anal come to practice their craft I think.
Regardless, thank you for the insight. I read someone say that you could remove the code behind from a view and still have it work fine. I am sure that was purely contextual though.
By the by, should the MoXAML power toys work with VS 2010 or just 2008?
Cheers, --EA

At the moment, it's just 2008 - when I've finished the article I'm working on, I'll be upgrading it to 2010.

I am in the same boat as you, just getting started with SL. Having read a swag of articles, studied a number of frameworks and discussed it to death we are now getting into some development. I agree with Pete, only the anal will argue that there should be no code behind. I find we end up with quite a lot sitting in code.
When the renderer in VS10 won't render the view because it can't deal with the viewmodellocator I have no compunction doing the binding in code therefore making the IDE behave.
There seems to be lots of stuff that is purely View related that still need to be done in the code.
