1,396 Points¿how can I set two models in a single view?
I think this is an interesting question but I don't know how, maybe I have to make a model that returns all my models, does someone has a code example?

I haven't seen this in a class here (but I have not taken them all), but you can find plenty references online, including this chapter in a Microsoft Tutorial.

public class Model1{}
public class Model2{}
public class MyViewModel
{
public Model1 model1;
public Model2 model2;
public MyViewModel (Model1 mo1, Model2 mo2)
{
model1 =mo1;
model2=mo2;
}
}

231,264 PointsIt looks like you've altered the controller's signature by giving it a constructor that requires arguments. Have you also altered the code that instantiates it to accommodate?

1,396 Pointshttps://github.com/PequeCeci/Guava.git here is my project, I made a model for making the slider dynamic but I already had another model so I don't know how to use both models in a ViewModel that contains both models.
