MVVM Session 03 – Model Validation with IDataErrorInfo

In the third part of my MVVM Series on my YouTube channel I educate how you can use the IDataErrorInfo interface in WPF using MVVM to do validation. This approach applies equally to your models and view models, although in the video I focus primarily on the model.

Watch on YouTube now.

    Hi David,

    Thanks for the great instructional videos.
    Exploring the world of C#-WPF-MVVM (all new to me) and this has helped me a lot.
    Is the code from part 3 still available somewhere ?
