Excellent video, good work! This is the first MVVM tutorial I've seen that actually explains why you should use MVVM. It makes it so much easier to understand MVVM when it is desciribed in the context of an evolution from the old 3 tier architecture.

[@Ididitagain66]

Great video, this video is one of the best explanation of MVVM i have seen - thank you.

[@GavinBath]

I've been struggling to understand MVVM, but I think I "get it" now. Thank you for such an awesome explanation!

[@roflex2]

You are a great teacher, the fact you have this put up for free is an even better service to the programming community.

[@ipelengmolete161]

Finally, someone who explained the what and the why in such a simple, understandable way - now I understand what each component does and how they interact. That "Glue Code" explanation was the game-changer for me. Thank you so much, now I know what's going on

[@deejung_xyz]

After watching hours of other content, I'm finally glad to stumble upon this one. Thank you very much!

[@DarkMagicDesigner]

Fantastic video! I really appreciate that you made it as simple as possible while giving enough broad context as to how and why these patterns evolved. Very helpful!

[@kalp1200]

I wished I saw this earlier...your explanation is so helpful for a beginner like me. Thank you sir.

[@jainikprajapati1632]

Very good explanation....for beginners

[@JustMeNoElse]

This is the first time i found a comprehensive lesson for MVVM. Thank you so much.

[@gaurangnaik8192]

I knew I would get all the answers to my questions from Shiv sir. Amazing explanation

[@argusreynolds2726]

I feel like a huge light has gone off in my head! Thank you for this video.

[@jaeranxwhitterker1578]

Beautifully made tutorial that is simple enough to introduce a complex subject. Thank you so much.

[@zerosandones7547]

MVVM (Model View View Model) is an GUI architecture pattern - MVVM is the evolution of the 3 layer architecture UI BL (Business Logic) DAL (Data Access Layer) - the 3 layer architecture violates SRP (Single Responsibility Principle) (because some layers are performing extra work which they are not supposed to do) - MVVM solves the "glue code" between UI and business logic layer (the "glue code" between business logic layer and data access layer is solved by repository pattern) - types of glue code: (the "owners" of this "glue code" is the UI code behind, which means some business logic codes are now part of the UI [typically at .xaml.cs file of our UI]) - binding/mapping code e.g.: txtCustomerName = customer.Name; - this code sends data from the ui to the business logic layer or probably takes the data from the business logic layer to the ui - transformation code e.g.: if (person.Gender == "M") { chkGender.IsChecked = true; } else { chkGender.IsChecked = false; } - data formats of the business logic layer and the ui can be different like the code above, the business logic layer's property (Gender) has values M for male and F for female, but when this data is displayed in the UI it is a checkbox (The UI doesn't understand "M" and "F" the UI only understands true or false) - When we use MVVM architecture, we divide the project into three layers: View View Model Model - in MVVM each layer handles its own responsibilities [VIEW] - the view will refer the viewmodel (by "adding a reference") - the view will invoke the viewmodel and the view model will invoke the model - all the calls FROM the view will come TO the viewmodel, and the viewmodel will send those calls(FROM the view) TO the model [VIEWMODEL] - the viewmodel will refer the model (by "adding a reference") - the viewmodel will be "using" the model - has the logic that binds the View and the Model - is a class library - the view model will invoke the model - whatever data you are exposing from a view model it should be of the least denominator type (do not try to use UI specific data type / UI technology specific data type) [MODEL] - the (most typically) real life object that you are trying to create - is responsible for exposing data in a way that is easily consumable by WPF Advantages of MVVM - Contain changes - when we make changes in one place, we don't have to change all across our project - Increased reusability

[@VBATutor]

Really nice video.. I could not find next video that was referred (commands in WPF MVVM). Can you please help me out in finding the video? Thanks

[@fiszunio]

Thank you so much. This tutorial is very helpful for beginners like me.

[@Roan_W]

Just came across this today and wish I had found it a lot sooner! Absolutely amazing job explaining this.

[@jaankie18]

I love watching all QuestPond videos. So useful and explained in very simple language. I highly recommend my friends to watch it for any kind of training. Keep it up. We need you.

[@mahmoudzeort7078]

Excellent video! Talented teacher

[@chrisn4730]

I've heard people say that using 3 tier architecture means contained changes but that is often not the case with UI changes. Whenever you make a UI change you almost always have to make a change to the data access layer too.

[@afghanboy4022]

thank you . it was the best tutorial which presents best way of learning WPF MVVM .i wish you had a such tutorial for bindings and references in WPF.

[@ravindrababu2780]

It's really awesome vedio , explained in an easy way to understand... Gr8... I am not able to find other vedios..

[@jurgenbartalis1933]

Great! What a detailed and understandable explanation of MVVM. Good job!

[@RonyCuzco]

hello! thanks for the tutorial!! I think some things have changed since, because whenever I wanted to set the IsMarried Property in the xaml,i got an error specifying that since the property (in the viewmodel) was readonly, i could not specify a value. So in this: the IsMarried="True" part was giving the error. I fixed it adding a setter to the IsMarried property in the viewmodel.

[@amarnileshjogoo4237]

Hi, Could you please help with how to place the setter. I have added the following setter, but the check box does not get updated at run-time: public bool IsMarried { get { if (obj.Married == "Married") { return true; } else { return false; } } set { obj.Married = Convert.ToString(value); } }

[@anwerazeemch]

this is working fine for the set default values in the xaml but it is not working with actual data binding for the values set outside.

[@boho2005]

[@elamaranelamvazhuthi4744]

Great video. Thank you so much.

[@handover007]

what should be binding property source when the values are set outside this file.

[@r1pfake521]

Nice tutorial, but i have a question about this example with C# WPF it's possible to use converters in the binding, so it would be possible to skip this view model and bind the view to the model directly and then add converters to the binding to transform the int to a color, or the string to a bool etc Would this still be considered MVVM in this case if the View is directly bound to the Model properties with binding converter classes?

[@nitishkumarchandan]

Many Thanks for this video...

[@Farrukhw]

Actual MVVM starts at 18:15. However before that its very informative...
