c# - Retrieving the TabItem hosting a nested WPF Control -


i have nested controls on wpf tabcontrol. need find specific tabitem parent of control. preferably using linq. ideas.

a non-selected tabitem don't exist in visual tree, in logical tree.

i've made small example on this:

<tabcontrol x:name="tabcontrol">      <tabitem header="test 1">             <button content="click tabitem name" margin="100" click="btngetparent_click"/>      </tabitem>      <tabitem header="test 2"/> </tabcontrol>

clicking on button inside tabitem should display tabitem's header meaning have access , able work need.

i've kept code pretty simple here too:

public partial class mainwindow : window {     public mainwindow()     {         initializecomponent();     }      private void btngetparent_click(object sender, routedeventargs e)     {         tabitem ti = tryfindparent<tabitem>(sender button);         messagebox.show(ti.header.tostring());     } }

and helper method:

    public t tryfindparent<t>(dependencyobject child)     t : dependencyobject     {         dependencyobject parentobject = logicaltreehelper.getparent(child);         if (parentobject == null) return null;          t parent = parentobject t;         if (parent != null)             return parent;         else             return tryfindparent<t>(parentobject);     }

the call logicaltreehelper instead of usual visualtreehelper job here.

give try, hope helps.
