Keyboard Response & MVVM

[Terry Foster]

I have a couple of related questions:

First, according to the documention, I see that one can use the 'RadWindow.ResponseButton' attached property to associate a button with the 'Enter' or 'Escape' key presses.  However, it only mentions that the button's Click event is invoked when the key is pressed.  I'm not seeing any mention of the bound 'Button.Command' being executed, which is what is needed in an MVVM scenario.  And, indeed, it doesn't seem to work when I try it.  Is there some way I can get this to work?  If not, are there plans?

Second, I actually already implemented a framework where, in XAML, I can tag any control with the button that is associated with the 'Enter' and 'Escape' keys.  This framework relies on handling the 'UIElement.KeyDown' event and it works great for pretty much any kind of FrameworkElement container - Grid, StackPanel, ChildWindow, etc.  However, it doesn't work with the RadWindow, apparently because it seems to be suppressing the KeyDown event - at least, it never seems to be getting raised.  Do you have any idea why this would be the case and if there is some way to not suppress this event?

Thanks,
Terry Foster

Hello Terry, 


Straight to your questions:

1. I would suggest you to use the RadButton control, because in the Button control there is a bug. Attached you can find the sample. Please, look at it and let me know if this helps.
2. Could you please give us more detailed information about your scenario? If you send us a sample project that reproduces the problem it would be very helpful. I am glad to assist you further.

All the best,
George

It turns out that the RadWindow is raising the KeyDown event just fine, but it didn't appear to be because of the focus issue discussed in my other thread: http://www.telerik.com/community/forums/silverlight/window/major-focus-tabbing-issue-with-showdialog.aspx.  My keyboard response framework works just fine when the RadWindow properly gets focus.

Thanks,
Terry

Hello,

I would suggest using the Keyboard.Modifiers static property to get whether the Control key is pressed or not:

private void UserControl_KeyDown(object sender, KeyEventArgs e)
        {
            if (Keyboard.Modifiers == ModifierKeys.Control && e.Key == Key.W)
            {
            }
        }

I hope this helps.
