wpf - Binding preference: Name or Type? -


knowing mycontrol has depprop. px1, binding should prefeer, line1 or line2?

<usercontrol x:class="myproject.mycontrol"              xmlns:my="clr-namespace:myproject"               x:name="parentcontrol">      <canvas>         <line x:name="line1"                x1="{binding relativesource={relativesource ancestortype={x:type my:mycontrol}}, path=px1}" />          <line x:name="line2"                x1="{binding elementname=parentcontrol, path=px1}" />      </canvas> </usercontrol>

i mean, should ensure uniqueness of name "parentcontrol" per possible parents in second case?

i prefer latter syntax in cases, it's easier read intent, long choose clear name parentcontrol. down side fails if change name, whereas first continue work.

side note: px1 doesn't need dp, long usercontrol implements inotifypropertychanged , notifies when px1 changes.
