Answer 1

There are a couple of things wrong here:

1. Your view is typed to Rezultat but you're trying to treat the model as an IEnumerable.
2. You're trying to bind each textbox to x[i] - which would be equivalent to Model.x[i] - when what you really want is to bind it to [i].x (i.e. Model[i].x).

So, to correct this, you need to change a couple of things.

First, change your view to inherit System.Web.Mvc.ViewPage>. Now your view can pass an IEnumerable, which is what your controller action expects.

Second, change this:

To this:

The reason for this is that the first will attempt to bind the value to Model.x[0], which is (or will be, once you've typed your view properly) equivalent to the first element in property x of an instance of IEnumerable. This obviously isn't quite right, as an IEnumerable exposes no property x. What you want is to bind Model[0].x, which is the property x of the Rezultat object at index 0.

Better still, use a helper to generate the name for you:

for(int i=0; i < Model.Count; i++)
{
    @Html.TextBoxFor(m => m[i].x)
}
