Hi Everybody.
I have an action method in a controller as below:

public async Task<ActionResult> abc()
        {
            string nexturl = "this is a dynamic value"
            ViewBag.Data = nexturl;

            return View();
        }

Where above Action Method does some data checking then pass a value to the View and return a specific view. Within the view If I scroll down to 60px I'll be redirected to another action method in controller which is as below:

public async Task<ActionResult> abcGetMoreData(string nexturl)
        {
            if (nexturl != null)
            {
                // somme logic
            }
            ViewBag.Data = nexturl;
            return View("abc");
        }

Above action method takes a parameter which is fed by 'abc' view with ajax. then do some checking and sends back a new value for nexturl to the view. If the user scroll the next 60 px he/she will be redirect to the same action method 'abcGetMoreData' and continues until the nextUrl become null.
What I want is to make this thing easy for the user. I want to load all data in once so do user shouldn't scroll down to get more data. How can I achieve this?

I haven't tried anything as far as I am very new to C# and MVC.
