WPF TextBox Overwrite

Question

In WPF, is there an easy to allow overwriting of text in an textbox?

Thanks
Tony

EDIT: I guess i wasn't to clear. Sorry.

I have a TextBox that the user is allowed to type 6 characters. If the user types 6 characters and then for whatever reason put the cursor at the start or somewhere in the middle of the 6 characters and starts to type, I want what they are typing to overwrite characters. Basically act like overwrite mode in Word.

Thanks again.

I would avoid reflection. The cleanest solution is the following:

EditingCommands.ToggleInsert.Execute(null, myTextBox);
