How to filter my WPF-combobox?
<p>first of all: sorry for the bad english, its not my first language.</p>

<p>I am currently working on a project where i have a list of persons which i want to list up in a combobox.
I want the combobox to get filtered, so that there are only the people listed up i am searchig for.</p>

<p>For example if i type in the combobox "Joh", there should only be people who start with "Joh" like "John", "Johann", ... .</p>

<p>The next thing is, my combobox is not "editable", how can i make it that i can write in it ? Currently it is "locked" ...</p>

<p>I hope you understand whats my problem, and how to solve it!</p>
