Define DataGrid.InputBindings for all DataGrids in application

is there a way to define DataGrid.InputBindings for all DataGrids in my application? I have my own command therefore I place:
<DataGrid.InputBindings>
<KeyBinding Command="{Binding MyOwnCommand}" Key="Delete"/>
</DataGrid.InputBindings>
in every DataGrid... I've tried to set this as style without any success.
Thank you in advance!

Set KeyBinding on a whole WPF window

I working on an MVVM window and want to control something in the view model by the keyboard, but if i place the following code directly under the window it can't be compiled only if i place under for example a text box. How can i do this?
<KeyBinding Key="P" Command="{Binding ToggleCommand}"/>

You need to assign the KeyBinding to the InputBindings property on Window
<Window.InputBindings>
<KeyBinding Key="P" Command="{Binding ToggleCommand}"/>
</Window.InputBindings>

WPF Bind button to key pressed

I have not done WPF development before.
I am creating a calculator. I want the "one" button to be bound to the keyboard key "1".
So the click function of my button must execute when the keyboard key "1" is pressed.
Please advise on how to do this>

use this:
http://msdn.microsoft.com/en-us/library/system.windows.input.keygesture.aspx
<Window.InputBindings>
<KeyBinding Command="{Binding MyCommand}"
Gesture="CTRL+R" />
</Window.InputBindings>

Handling keyboard press in WPF

I am only beginning to learn MVVM and its use in WPF.
I am using it to build a very simple Calculator application (like the Windows built in calculator).
One thing i've noticed, is that binding my view (XAML) to commands does not let me configure WHEN these actual commands are fired.
For example, a Button control fires the command bound to it when it is clicked.
I would like to achieve the same effect when the numpad buttons are presed ('1' will fire the Command of the "1" Button control, and so on).
I could not find 1 way to do this, all sites seem to show multiple other options which don't seem valid in this case.
Should this be set up in the Control's (Button) level or on the entire window? How can i do this ?

Try to set input bindings of your main window.
<Window.InputBindings>
<KeyBinding Key="D1" Command="{Binding Command1}" />
<KeyBinding Key="NumPad1" Command="{Binding Command1}" />
</Window.InputBindings>

Triggering Silverlight Prism command with a keyboard shortcut

Does anybody know whether one can trigger prism command with a shortcut? What I mean is I want to be able to define binding of a command to keyboard shortcut in declarative manner, like ClientUI does:
Are there any opensource libraries for that purpose? Or maybe code samples?
I found this question but I don't think that it answers mine.

I've created such gesture trigger. And I'd like to share it with you guys. Basically, it is System.Windows.Interactivity trigger which can parse gestures represented as strings. Usage is as simple as in ClientUI:
<UserControl>
<i:Interaction.Triggers>
<behaviors:KeystrokeCommandTrigger Command="{Binding SaveChangesCommand}" Gesture="Ctrl+Shift+S" />
<behaviors:KeystrokeCommandTrigger Command="{Binding RejectChangesCommand}" Gesture="Ctrl+Shift+R" />
<behaviors:KeystrokeCommandTrigger Command="{Binding NewItemCommand}" Gesture="Ins" />
<behaviors:KeystrokeCommandTrigger Command="{Binding DeleteSelectedItemCommand}" Gesture="Del" />
<behaviors:KeystrokeCommandTrigger Command="{Binding UploadSomethingCommand}" Gesture="Ctrl+Shift+U" />
</i:Interaction.Triggers>
</UserControl>
The code is on pastie.

You could write an attached behavior that has a listens to the KeyUp event and then calls the Command. The complication comes in translating something like Gesture="Ctrl+Shift+A". You would need to write a parser to figure out exactly what key combination that string represents.
