c# - WPF Caliburn.Micro/mvvm Navigation -


i'm building project, , 1 of biggest problems i've come across until navigation.
i've been looking time examples of caliburn.micro/mvvm navigation, seem long , couldn't understand of (beginner here!).

some info project:
want there outer window/shell, menu links/tabs open pages according button clicked inside inner part of shell, , able open change page within one.

i have: shellviewmodel.cs, mainviewmodel.cs, models, , views. for now, need know how make mainviewmodel load inside shellviewmodel on startup(using contentcontrol/frames...), , how move 1 page another.

you write in points, , link me useful examples, , believe continue there. it'd best thorough explanation of stuff if possible.

have read conductors , screens on official documentation.

as simple example, shellviewmodel conductor of 1 active screen (i.e. 1 screen becomes active/inactive @ time):

public class shellviewmodel : conductor<iscreen>.collection.oneactive

you can set activeitem of conductor view model instance wish active:

this.activateitem(mymainviewmodel);

a collection conductor type provides items collection can populate instantiate new windows. viewmodels in items collection may deactivated not yet closed, , can activate them using activateitem above. makes easy create menu of open windows using itemscontrol x:name="items" in shellview.

then, create shellview, can use contentcontrol , set name same activeitem property, , caliburn.micro rest:

<contentcontrol x:name="activeitem" />

you can respond activation/deactivation in mainviewmodel overriding onactivate/ondeactivate in class.
