How do I deselect everything in a WPF window?

Does anyone know if there is a way to deselect everything on a WPF window? I've seen some applications do something similar, often when pressing the escape key. What it appears to do is to put the window back in the state when it was first loaded, before the user clicks anything or tabs to a control on the window.

What I have tried:

Nothing really because so far I haven't found anything that looks like it will do anything I need.

I am thinking of maybe trying to have an invisible control and setting focus to that, but this feels like a complete hack.

deselect everything means?
Which controls/what are selected here?

It is a set of TextBox controls inside a Grid. It just would feel more natural if pressing Esc or clicking on a 'blank' area of the window removed selection from whichever TextBox currently has keyboard focus.

That would be a complete hack because you loose control over what gets deselected if this requirement ever changes.

The proper solution is to write the code to go through the controls and clear the selections however it needs to be done for each. It's not the sexiest solution but it's maintainable and debugable.

You can then call this method from an event handler or from some other code if required.
