Disable tab key

When pressing tab on the keyboard, the next focusable UI element gets focused automatically. Is there a way to disable this behaviour? I've tried to set the tab index on every focusable element to 0, but that doesn't seem to help.

I'm using a custom input wrapper (derived from UIElements.Runtime.InputWrapper), but there is apparently no way to get control over keyboard input.

 

I know this is already an old thread, but it looks like you can disable them by setting the tab index to -1 instead of zero.
