WPF Getting Control null reference during InitializeComponent

Question

So my InitializeComponent method call in the Window\'s constructor is running through the XML and adding the controls and plugging them into their events.

Answer 1

It was the Checked event on a radiobutton. When i removed Checked="true" from the xaml the issue went away. (though it is checked when the Window starts). Not sure what's going on here, but at least I didn't have to change anything major to fix it... yet.
