I'm developing an application that manages Courses , I'm a beginner in ASP.NET MVC. In my application I have a screen that the Student makes your Enrollment in a course, I also have a field Number of Jobs and another field Status that says whether the course is Available or Closed , what I am trying to do is: When my Amount of vacancies reach zero the Status of the course should change to Closed . I do not know if javascript
would be the best way to do this. The way I tried it is wrong and it does not work. Can someone help me?!
MyView
@model IEnumerable<MeuProjeto.Models.Curso>
<style>
#Status {
display: block;
text-align: center;
}
.encerrado {
background-color: green;
font-family: 'Times New Roman';
color: white;
}
.disponivel {
background-color: orange;
font-family: 'Times New Roman';
color: white;
}
</style>
