Answer 2

try

FocusManager.SetFocusedElement(txtCompanyID)

Answer 3

txtCompanyID.Focusable = true;
Keyboard.Focus(txtCompanyID);

msdn:

There can be only one element on the whole desktop that has keyboard focus. In WPF, the element that has keyboard focus will have IsKeyboardFocused set to true.

You could break after the setting line and check the value of IsKeybiardFocused property. Also check if you really reach that line or maybe you set some other element to get focus after that.
