I will bring code first.
Controller:
public ActionResult VideoList(int page)
{
}
[HttpPost]
public ActionResult SaveWindowWidth(string width)
{
return Json(new { success = true });
}
JS:
$(document).ready(function ()
{
var width = $("#Window").width();
$.ajax(
{
type: "POST",
url: '/Video/SaveWindowWidth',
async: "true",
data: { "width": width },
dataType: 'text json',
contentType: 'application/x-www-form-urlencoded; charset=UTF-8',
success: function (data, status)
{
if (data)
{
alert(data.status);
}
},
error: function (data, status)
{
if (data)
{
alert(data.status);
}
}
})
})

Problem that ajax tries to call VideoList method. I see it when read response:
The parameters dictionary contains a null entry for parameter ‘page’ of non-nullable type ‘System.Int32’ for method ‘System.Web.Mvc.ActionResult VideoList(Int32)’
I have heard somewhere that it may be something wrong with routes, so I posted them here as well.
I would appreciate your help

Your video route is not well configured. MVC tries to get the controller and action from each url to figure out required method from appropriate controller. And in your case, it always gets same values VideoController.VideoList():
If you change your route to this, everything will be ok:
