If Pinned state of ContentPane changes I experienced that loaded event of all controls in it (UserControl and its child control) gets fired. This thing resets the settings I applied in the loaded event of Usercontrol and its child control.

Why Loaded event of each contol in ContentPane gets fired on Pinned State change..?

If this  is a bug then in which version it is resolved..? I am using v9.2 (9.2.20092.2094).

Thanks Andrew

Works great!

Hi Andrew,

Yeah I had no idea what to do with that ToolWindow the last time (the online help is of little help), so I just went on to more pressing matters.  I just tried the code you posted and this seems to work perfectly.  Thanks a lot!!

So just to be clear, you have commands associated with commandsource elements (e.g. a Button with the Command set to some routed command). Once the pane is floating the ancestor of the xamDockManager which was handling (either via events or commandbindings) the CanExecute/Execute for those commands is no longer getting those calls for the floating panes. If that's the case then you can work around this by handling the ToolWindowLoaded as I mentioned originally. Then you can either add CommandBindings to the ToolWindow or better still handle the CanExecute/Execute generically and reraise them on the dockmanager. In thinking about this it seems like the xamDockManager should do this itself so I'm going to write up an issue for this but in the interim you can do something like the following to delegate the CanExecute/Execute.

private static void OnToolWindowCanExecuteCommand(object sender, CanExecuteRoutedEventArgs e)
{
 PaneToolWindow tw = sender as PaneToolWindow;
 XamDockManager dm = XamDockManager.GetDockManager(tw);

 if (dm != null)
 {
  RoutedCommand rc = e.Command as RoutedCommand;
  if (null != rc)
  {
   // if the CanExecute reaches the ToolWindow then nothing has 
   // handled it. we'll delegate the canexecute call to the dockmanager
   // and let it bubble up from there
   e.CanExecute = rc.CanExecute(e.Parameter, dm);
   e.ContinueRouting = false;
   e.Handled = true;
  }
 }
}
private static void OnToolWindowExecuteCommand(object sender, ExecutedRoutedEventArgs e)
{
 PaneToolWindow tw = sender as PaneToolWindow;
 XamDockManager dm = XamDockManager.GetDockManager(tw);
 if (dm != null)
 {
  RoutedCommand rc = e.Command as RoutedCommand;
  if (null != rc)
  {
   // if the Execute reaches the ToolWindow then nothing has 
   // handled it. we'll delegate the canexecute call to the dockmanager
   // and let it bubble up from there
   rc.Execute(e.Parameter, dm);
   e.Handled = true;
  }
 }
}
private void OnToolWindowLoaded(object sender, PaneToolWindowEventArgs e)
{
 e.Window.AddHandler(CommandManager.CanExecuteEvent, new CanExecuteRoutedEventHandler(OnToolWindowCanExecuteCommand));
 e.Window.AddHandler(CommandManager.ExecutedEvent, new ExecutedRoutedEventHandler(OnToolWindowExecuteCommand));
}
