Where to create parametrized ViewModel?


wpf mvvm viewmodel

Use an ObjectDataProvider if you want to specify constructor parameters: 

<Window.DataContext>    <ObjectDataProvider ObjectType="vm:MyViewModel"        xmlns:sys="clr-namespace:System;assembly=mscorlib">        <ObjectDataProvider.ConstructorParameters>            <sys:String>A string parameter</sys:String>            <sys:Int32>42</sys:Int32>        </ObjectDataProvider.ConstructorParameters>    </ObjectDataProvider></Window.DataContext>

wpf mvvm viewmodel

I have no idea how to pass a contructor-parameter, I think it can't be done (but it would be nice if someone proved me wrong).

What you can do is set properties on your ViewModel, as in 

<Window.DataContext>    <vm:MyViewModel  MyProperty="Hello" /></Window.DataContext>
