How to hook into key press in WPF


This post is regarding implementing keyboard shortcuts for your control. When you create an enterprise application, Keyboard shortcuts are a must. Enterprise applications will need keyboard shortcuts to execute certain actions in controls which are possible only by using the mouse. Keyboard shortcut is different from keyboard access key where it will help you to get the focus on to control. Here we will use InputBindings to achieve this. InputBindings represents a binding between an input gesture and a command.

 <KeyBinding Command="{Binding CancelButtonCommand}" Key="Escape" Modifiers="Control" />

I have wide range of interests and getting my hands dirty in technology is one among them. I use this platform primarily as my knowledge base. I also use this platform to share my experience and experiments so that it might help someone who is walking the way I already did. The suggestions expressed here are the best to my knowledge at the time of writing and this may not necessarily be the best possible solution. I would pretty much appreciate if you could comment on it to bring into my notice on what could have been done better.
