Question

Is it possible to use [Required] attribute in model, but not in controller.

For example I want to use object in which I will set several parameters, and for the class of this object I want to set attribute [Required].

Is it possible to use logic like ModelState.IsValid or something like it.

Here is an example of code:
EmployeeModel employee = this.ToObject(employeeXml);

Employee model has property Name. This property is required. How to verify it?

You can use TryUpdateModel method which update ModelState according to model validation rules:

public BranchWizardStep GetNextStep(FormCollection formCollection)
{
    TryUpdateModel(_someModel);

    if (ModelState.IsValid) 
    {
        //...
    }
}

EDIT:
But better to use TryValidateModel method which validates model only.
