How to detect that a control is bound..
Hi all, I need to attach an event to a ViewModel object that is bound to a control via DataContext. The problem is, I can't attach the event in the constructor because the DataContext object has not been set at that point. So how do I attach that event if I want it to execute code within the control? I can't seem to see an OnDataContextChanged event, or anything like that. Does anyone know what I am supposed to do here? Regards, Tony ___ ozsilverlight mailing list ozsilverlight@ozsilverlight.com http://prdlxvm0001.codify.net/mailman/listinfo/ozsilverlight
RE: How to detect that a control is bound..
In WPF you can override the OnPropertyChanged event and wait until the DataContext property comes through in the event args. You can then check e.NewValue to see what it's binding to. I'm not sure if Silverlight implements this the same way though. Carl.

XAML Intellisense lost
Folks, after rebuilding my Win7 PC with Visual Studio 2010 and all of the Silverlight dev kits and tools I have found that the XML/XAML intellisense has vanished from Visual Studio. The XML/XAML is now as dumb as plain text. Does anyone know how to get my intellisense back again?

The intellisense is just dead no matter if I open it via the WPF Designer (Default) or the XML edit, with or without encoding.

RE: XAML Intellisense lost
I have found that the problem of the missing intellisense is intermittent. It will occasionally start working again, but not very often, and I can't find any pattern yet behind what's going on. Surely I'm not alone in having a Silverlight/WPF designer in Visual Studio 2008 what is broken to hell and back. Besides the mostly broken intellisense, opening XAML in the designer causes Visual Studio 2008 to randomly and frequently crash completely with the Send or Close dialog. It will not response to the Close button and I have to kill the devenv.exe task. If VS2008 restarts and the XAML file was the last one open, it will attempt to reopen it and crash immediately. I have to manually delete the *.suo files and restart Visual Studio. Ignoring the fact that the designer doesn't actually design anything at all -- it's just a XAML editor -- the highly unstable experience makes developing Silverlight in Visual Studio a living hell and nearly doubles my development time. At Code Camps and evening SIG meetings I never hear anyone complain about these sorts of issues. I was wondering if the experience was better in Visual Studio 2010 RC, but when I created a new Silverlight project it crashed immediately before even loading the solution.
