I'm trying out MVVM with a simple project using WPF and I've got the grips on mostly how the pattern works and their intentions. However, one of my problem now is how navigation is done in MVVM. For example, when I have a navigation pane and I need to show a UserControl on the right-side of a window based on what item is clicked on the navigation pane. Or showing a new window.
How is this done in MVVM? I've browsed the internet but all implementations I see uses IoC containers. I want to implement the application without these frameworks as I want to understand how it works. Some have mentioned using controllers for navigation but I can't seem to find a simple and short example.
Basically, I need a short and simple example of how it navigation is done in WPF MVVM.

It's almost a week I've been trying to find a way to implement a Navigation Menu in WPF using MvvmCross 7 with no success. I had no luck even doing a research with similar solution, my impression is MvvmCross is mainly used with Xamarin and that WPF is not used at all. At this point I'm suffering a deep loneliness.
The idea is simple: show a view inside a main view in order to change it dinamically. The main view is the menu with all the buttons and the child view is the content of the button pressed.
I' ve been able to achive it using this https://www.codeproject.com/Articles/5275552/WPF-Compact-Navigation-Menu but I won't feel good until a find the correct way using MvvmCross.
Can you give me a starting point or some hints?
How do I use multiple windows in an WPF MVVM app?
I have a Main Window with a menu control that needs to open up new instances of the window each time the item it is selected. I need to be able to show windows next to each other, it is a requirement and not page or usercontrol navigation.
Does anyone have an example of doing this?
I've read it is not recommended UI design but it is the requirement I have to implement.
Actually I have this working by using the WindowManager from Caliburn.Micro which seems like an very excellent framework for this type of application. I did look into prism but it seems over complicated and Caliburn is very easy to understand which did meet the requirements. I looked into MVVM Light but the documentation is horrible and lacks examples and I don't have time to figure it out.
I am new to WPF/MVVM and I need to create a single application window.
To clarify, I would like to have a single window with a basic menu, which, depending on the option clicked on that page/window, launches a completely new set of controllers within the same window (completely replacing the menu interface).
Basically, I'd like to be able to replace the content of the menu window, with the content of new user interface, and then to be able to go back to the menu interface again later.
Any directions? Thanks.
PRISM Navigation is the way to go. You can read about PRISM Navigation on MSDN. It provides a good explanation with a lot of code samples. Karl Shifflett also has a couple good blog posts here and here which are helpful.
I am new to WPF and I am facing a problem here. In one of our application, few dialogs responsible for similar kind of work. All dialogs have OK and APPLY buttons. But in our new UI Design, these will be displayed on a side bar which is a panel(Yet to decide control). I thought of having a Base Usercontrol which will have OK and APPLY button with few methods. And my other dialogs(which are Usercontrols now in new UI) are derived from this Base User Control.
I downloaded few code samples from internet, but problem didn't solve.
If you have any idea/code sample please share.
Thanks in advance.
WPF (also WinForm to some extent) doesn't play well with inheritance. You could create the UI in C# code and get inheritance working but I don't think designer play well so you'll be stuck in design mode and in Blend.
To work around it you could create piece of functionality that you want to reuse and use composition instead of inheritance, which is considered a better approach anyway.
Here is my problem: I am migrating an application from Windows Forms to WPF, but I am totally new in WPF technology.
I have been lucky creating a ribbon also have been able to add some elements to it, but right now I am struggling to create a modal dialog.
How can I achieve this? I have already created all the design of the dialog, but I cannot get it open as a modal window.
Besides, since this application has to be developed under MVVM pattern, where could I place that code? According to what I've read, that code has to be place in the view class, am I right?.
Thank you in advance.
You show a WPF Window modally using Window.ShowDialog. Also this WPF Window Overview will help.

Look under the Related questions to your right, there are many answers to this question in there. For example:
