trees

when using treeview component in .net, of left tree. how can of right tree (windows native look) .net treeview?

what want "triangle" node handles , blue "bubble" selection square.

you need p/invoke call setwindowtheme passing window handle of tree , use "explorer" theme.

paste following code new class in project, compile, , use custom control instead of built-in treeview control.

c#:

public class nativetreeview : system.windows.forms.treeview {     [dllimport("uxtheme.dll", charset = charset.unicode)]     private extern static int setwindowtheme(intptr hwnd, string pszsubappname,                                             string pszsubidlist);      protected override void createhandle()     {         base.createhandle();         setwindowtheme(this.handle, "explorer", null);     } }

vb.net:

public class nativetreeview : inherits treeview      private declare unicode function setwindowtheme lib "uxtheme.dll"         (hwnd intptr, pszsubappname string, pszsubidlist string) integer      protected overrides sub createhandle()         mybase.createhandle()         setwindowtheme(me.handle, "explorer", nothing)     end sub  end class

note trick works same way listview control.

how set z-index drawing object when using drawingcontext.drawxxx() methods? the object drawn last have higher z index. can't change index of drawn objects. way draw in order. if using wpf (as placed tag), can use, example, canvas control. create shapes need like polyline obj = new polyline(); //... // ... set properties of obj and add them canvas uielementcollection: yourcanvasname.children.add(obj); //or yourcanvasname.children.insert(i, obj); first items of collection have higher z index. advantages in way: no need redraw on window changes, can anytime move objects , change order.
