One of the place I had to pass a value from a view to a partial view but I was not supposed to alter the model. Hence. I went back to the roots and used session to pass the value between the views. Whats important here is that, as it is a session value, you can pass it  from anywhere to anywhere. It will always be accessible. So here’s how to do it:

 

The beauty of session is, you can use it from anywhere:

Part 1: Saving the Value

1. From Controller:

public class Yourontroller : Controller
{
    public ActionResult SetSession(string value)
    {
        Session["YourSessionKey"] = value;

        return View();
    }
}

 

2. From View:

 

Snippet.cshtml
@model contracts.ModelName

@{

Session[“YourSessionKey“] = @Model.Name;

}

Part 2: Accessing the value:

 

You can again access this value in controller or view both.

 

In controller:

public class Yourontroller : Controller
{
    public ActionResult GetSession(string value)
    {
       var SessionValue=Session["YourSessionKey"];

        return View();
    }
}

In View:

Snippet

@model contracts.SomeOtherModel

@{
    int SessionValue = Session["YourSessionKey"];

}

 

There you go! Happy coding!
