Command Routing for Keyboard Shortcuts

Question

Basically, I want to create a keyboard shortcut that is valid within the window area, and not just turned on when the focus is inside the control that links it.

in details....

I have a window with three controls:

• toolbar
• text field
• User control

There is a button on the toolbar attached to the CustomCommands.CmdA command and associated with the Ctrl + T key combination.

My user management can handle CmdA . When I launch the application and click on my CmdA user control, it works and works fine. Also, Ctrl + T causes the command to fire.

However, when I select a text box, my custom CmdA command CmdA disabled.

I can fix this by setting the command target for the CmdA button. Now when I select textBox, CmdA is still on.

But the keyboard shortcut Ctrl + T does nothing.

Is there an easy way to zoom out on keyboard shortcuts? Or do I need to catch a keystroke somewhere below, and determine which command it is associated with and direct it myself (if so, in which environment can this be done?)

To do this, you just need to specify input bindings in the window, for example:

  <Window.InputBindings> <KeyBinding Key="N" Modifiers="Control" Command="New"/> ... </Window.InputBindings> 

For application built-in commands (which are RoutedCommands ) you need CommandBinding in the window.

 <Window.CommandBindings> <CommandBinding Command="New" Executed="CommandBinding_Executed" /> ... </Window.CommandBindings>
