c# - WPF Is possible to map Escape key in theme style -

i have searched , got following code working individual forms.

this.keydown += new keyeventhandler(handleesc);  private void handleesc(object sender, keyeventargs e) {     if (e.key == key.escape)      {          this.close();      } } 

the problem have code same on each , every wpf form in app. looking way put in theme style can avoid repeated coding. there way that?

thanks,

i don't think can done using styles. can though, create new layer between window , window class, , have intermediate layer take care of handling escape key. this, first create new class called escapewindow , have inherit window this:

namespace wpfapplication1 {     public class escapewindow : window     {         public escapewindow()             : base()         {             this.keydown += new keyeventhandler(handleesc);         }          private void handleesc(object sender, keyeventargs e)         {             if (e.key == key.escape) { this.close(); }         }     } } 

now every time create new window, can have inherit escapewindow instead of window. example mainwindow this:

public partial class mainwindow : escapewindow {     public mainwindow()     {         initializecomponent();     } } 

note since wpf windows partially defined in xaml, need change partial implementation. in case, mainwindow.xaml this:

<local:escapewindow x:class="wpfapplication1.mainwindow"          xmlns:local="clr-namespace:wpfapplication1"         xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"         xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml">      <grid>     </grid> </local:escapewindow> 

this might not make life easier since need change references every time create window, provides clean framework generically handling escape button.
