Yes. Don't use a routed command - use a Mediator instead. It's far more lightweight, and you can see a sample in action in my Twitter application here[^].

You can use an attached behavior to execute the command.

Download this code from Jaime's and my training sessions.

http://www.cookingwithxaml.com/content/ChicagoLob/demos.zip[^]

Look in the Southridge project for the RibbonTabSelectedBehavior.

Then modify it for your purposes. You can also do a search on "wfp attached behaviors" and read up on these.

You should be able to say Source="../Images/Img.png"

This is not a namespace problem perse, just one that looks like it because of the way most people group their files into namespaces combined with how the XAML compiler/parser compiles and looks up resources.

WPF custom control

Hi,
I am developing WPF custom controls. My problem is how can get an event when the user has deleted a control from the Cider (WPF designer). The Unloaded event is triggered for a control when its deleted from cider and also when the WPF Window is closed. I want a event which is fired only when a control is deleted from cider.

// Register the callback for the control Unload event 
// This Callback is called for control deletion and when the WPF window(.XAML) 
// is closed in cider.               
this.Unloaded += new RoutedEventHandler(ControlUnloadedCallBack);
.
.
.
 private void FSFControlUnloaded(object sender, RoutedEventArgs e) {
   // notification called
   }

thanks in advance,
Vinod C S

You can detect in code if you are in the designer, so put your code inside the event inside a block so it doesn't fire at runtime.

You'll probably want to change the template of the button to give it a different
layout. The section "Creating a ControlTemplate" in the Controls Overview[^]
has an example.

idle means => user is not doing anything using any input (like: keyboard or mouse etc.). He is not using the machine for a long period (say about 5 minutes)

I can give you some hint..hope this help you..
Make some global variable say 'xyz' in app.xaml and initialize it to 0.

and take one timer whose code executes after each minute and increase value of variable 'xyz' by 1 and if it become 5, then write code what you want..

and for anything you do using keyboard or mouse input at that time make the value of 'xyz' to 0..

This will be quite difficult if I use two many Windows in my application. This will also produce huge garbage code.... Frown | :(

Need some feed back on my new Silverlight articles

Hi,

I just completed two articles on Silverlight. The first is real basic 1.0 stuff. The second is 2.0 and more architechuraly involved but geard toward developers. I would like some community feed back and any performance results you find while testing the code. I am working on an older Pentuim 4 willimina with low memory. I'm getting bad performance results, I'd like to know what beefier systems report.

Thanks in Advance,

Silverlight 3 Offline Application from Notification Area

I am curious to put my Out Of Browse application in Notification Area (Tray Icon). Especially when user minimizes my Out of Browser applications it should keep one ICON in Notification Area. Once he gets some alert or To-Do operation, it will show one “Notification Window” (like Outlook New Mail Notification Window). Is it possible to these kind of operations in Silverlight

I'm pretty sure the trust restrictions of Silverlight apps
will prevent you from using the system tray.

thank you Mark,
Can we customize Silverlight by extending dll's or can we use any third party controls to take care of Tray Area from Silverlight Out Of Browser application..

I am looking for these from long time, I believe once we get these futures we can do lot for our clients.

thank you,

Silverlight is a browser plugin and thus is meant to be cross-platform compatible.

The notification area is Windows specific. It's unlikely we'll see this
feature in Silverlight any time soon.

You should use WPF for full trust, full .NET framework features.

You can't do this because Silverlight is meant to respect the security Sandbox of the browser. That means that there are lots of operations you can't do such as interact with the desktop or file system outside of Isolated Storage. This is important because it helps to protect you from downloading malicious content from outside sources.

If you need desktop interaction, write a WPF application and download it using Click Once.
