my xaml:

if want button appear inside textbox control, need override control template textbox create custom control allow that. standard textbox control accept string (or numeric values) content.

you can make button inside textbox like:

    <border width="120" height="35"             borderbrush="black" borderthickness="1">         <stackpanel orientation="horizontal">             <textbox width="70" borderbrush="transparent"/>             <button content="mytag" margin="4"/>         </stackpanel>     </border>

enter image description here

you can change styling on textbox borderless , same color border object, , button inside textbox. border control becomes new outline of "textbox".
