AsP.Net MVC 5 how to call a function in view

Question

I have ASP.Net MVC 5 application I want to call a method from view how can I do it?

my code:

My UsersList function:

    public ActionResult UsersList()
    {

        var User_VM = new UserVM
        {
            MyUsers = context.Users.OrderBy(u => u.Email).Include(u => u.Roles).ToList()
        };

        return View(User_VM);

    }

UsersList View:

@foreach(var user in Model.MyUsers)
{
    <tr>
        <td>@user.Email</td>
        <td>
            @foreach(var r in user.Roles)
            {
                <p>
                    @Html.Action(GetRoleNameById(r.RoleId))
                </p>
            }
        </td>
    </tr>
}

and my function in controller:

   public ActionResult GetRoleNameById(string RoleId)
    {
        var RoleName = context.Roles.Where(r => r.Id == RoleId).FirstOrDefault();
        return Content(RoleName.ToString());
    }

Its a bit unclear why you would want to do this instead of populating the model in the main view in the first place, but its @Html.Action("GetRoleNameById", new { roleId = r.RoleId }) — user3559349

@Html.Action("Controller","Name", new { id = 1 }) This is Default.. Change with your own Controller and Method — Abdulla Sirajudeen

You can call your server method by using the overload of Html.Action() that accepts the action name as the first parameter and the route values as the 2nd parameter

@foreach(var r in user.Roles)
{
    <p>@Html.Action("GetRoleNameById", new { roleId = r.RoleId })</p>
}

You can achieve this purpose in many ways, on of them is you call make a ajax call to controller method. Something like this

$('#btnSave').click(function () {    
    $.ajax({
        url: "/ContollerName/GetRoleNameById" + "?RoleId=1", // change controller name here and pass proper role id.
        type: "GET",
        success: function (data) {
            if (data.status == "Success") {
                alert("Done");
            } else {
                alert("Error occurs on the Database level!");
            }
        },
        error: function () {
            alert("An error has occured!!!");
        }
    });
});

Also you can set content type in calling configuration
