Save variable value while navigation in MVC

Question

I am having one page ABC.cshtml. In the page I have written code for multiple modal popup with "Back" and "Next" buttons. when I click on buttons it navigates from one modal to another.

I am having "Id" which I need to persist when I navigate from one modal to another but "Id" became null.

I have used Tempdata/Viewdata/Viewbag/Hidden field to persist data but no use. I cant use session to save state here. Is there any other way to do this?

Can someone help me to solve this issue?

Thanks in advance.

You could use cache

Add System.Runtime.Caching

//Add cache named Key1. It will expire in 10 minute
CacheWrapper.Add("Key1", new List<int>(), 10);

//Get the cache
var result = CacheWrapper.Get<List<int>>("Key1");

//Delete the cache
CacheWrapper.Delete("Key1");

Create wrapper class like this

public class CacheWrapper
{
    private static ObjectCache cache = null;

    public static ObjectCache Cache
    {
        get
        {
            if (cache == null)
            {
                cache = MemoryCache.Default;
            }
            return cache;
        }
    }

    public static void Add(string key, object data, double expireInMinute)
    {
        Delete(key);
        Cache.Add(key, data, DateTime.Now.AddMinutes(expireInMinute));
    }

    public static object Get(string key)
    {
        if (!Cache.Contains(key))
            return null;
        return Cache[key];
    }

    public static void Delete(string key)
    {
        if (Cache.Contains(key))
        {
            Cache.Remove(key);
        }
    }
}
