Re: VS2010 SL4 Debugging - WPF Discussion Boards

VS2010 SL4 Debugging [SOLVED]

See this msdn post.

I installed VS2010 and SL4 (with tools and toolkit), and I can't get the debugger to stop anywhere in the code in a silverlight (v4) app - not even the first line of the constructor in App.xaml.cs.

Can anyone help?

(and before anyone asks, yes, the solution configuration is set for debug)

SOLUTION ======================

It seems that it's because FireFox executes plug-ins out-of-process, so the debugger can't attach to the appropriate process. The fix is described here:

Ran across something similar in VS2008 where the start project was set to the .web project, changing the start project to the main project fixed the problem - just a thought

It still doesn't stop (and I get a warning that if I don't set the web project as startup, I can't debug the RIA services stuff.

Do you have Visual Web Developer installed? When you install VS 2010, it includes this but in case you have chosen a different mode of install and omitted the Visual Web developer then it could be an issue. Do check and see.

I have "Visual Studio Web Authoring Component", but that was installed with VS2008.

Found this thread - it might help you.

Note: The workaround suggests that if VS2010 is run in administrator mode, this problem goes away.

#realJSOP4-Jul-10 3:14

Nope - it has no effect. I wonder if it's because I have VS2008 and all the SL3 stuff installed...

I had VS2008 installed and debugging VS 2008 did not create any issues for me.
I was however using SL3 even in VS2010 - so it could be something to do with having the SL3 and SL4 tools installed together.

The funniest thing about this particular signature is that by the time you realise it doesn't say anything it's too late to stop reading it.

WPF Designer Crash

I've been messing around with C# for about a year or so and I thought I'd have a look to see what WPF is all about. However I'm having a problem. Here's the problem -

If I drag a control (Button, TextBox TextBlock ,whatever) and I try to access the FontFamily property in the Poperties window then the designer will crash with the following error -

---

If the properties window is in "categorized" mode then all of the categories are open except the "Text" category. Any attempt to open that category will crash the designer also, (obviously because it contains the TextFamily property).

Anyone have a clue what is going on? I have tried to do a Repair on the Visual Studio installation but that didnt sort it out. I'm using VS2010 by the way. I also have VS2008 installed and that doesnt suffer from the problem.

TIA

Make sure to do not add more than one item with the same identifier or key

Curios as to why this doesn't work...

I have a WPF application which contains a ListView defined to show the values for an item in a chart.
One of the fields, State, is supposed to change as the charted values cross warning and alarm barriers.

I built up the list (which was really only one item) as follows:

ObservableCollection<LegendValues> itemList = new ObservableCollection<LegendValues>();
LegendValues item = new LegenValues();
... define the initial values ...
itemList.Add( item );
myListView.ItemsSource = itemList;


// further on in my code
item.State = "Warn";

I also have the binding set in XAML as TwoWay.
When I change the state in the item object, it does not change in the ListView. Is there something I'm missing?

Thanks,

Michael

INotifyProperty perhaps?

Well...according to the documentation all I need are two things. TwoWay link on the binding between the ItemSource object and the ListIndex, and the ObservableCollection. But I can add INotifyProperty and see if that helps.

ObservableCollection is only used to tell the binding engine when records have been added or removed from the collection. In order to watch changes to particular properties, you need to use INotifyPropertyChanged and raise the PropertyChanged event.

Have a read up on MVVM, in particular anything to do with the ViewModel portion of that design pattern and as Pete said it's all about the object INSIDE your ObservableCollection.
