How to fetch data about current user in ASP .NET MVC?

Question

So, I added a new Parameter to my ApplicationUser class, which is called SocialName . I would like to display it when user is logged in, at the top right corner. There, we have this piece of code:

@Html.ActionLink("Hello, " + User.Identity.GetUserName() + "!", "Index", "Manage", routeValues: null, htmlAttributes: new { title = "Manage" })

Now the thing is, I would like to display parameter other than Current user's username. I found passing the model to the Partial View problematic because I need to do it for every single action, otherwise I will have Null Reference . Do you have any ideas how to do this?

Answer 1

You can easily display info about user in partial view by Html.Action() method without passing info to every action. For example:

Your page/layout/...:

<ul class="nav navbar-nav navbar-right">
    @Html.Action("HeaderUserInfo", "Common")
</ul>

CommonController.cs:

public ActionResult HeaderUserInfo()
{
    var user = _workContext.CurrentUser; //get info about user
    var model = new HeaderUserInfoModel
    {
        Username = user.Username,
        UserId = user.Id
    };
    return PartialView(model);
}

and partial view HeaderUserInfo.cshtml:

@model Models.Common.HeaderUserInfoModel

<span><i class="icon fa fa-user"></i> @Model.Username</span>

You can get the user from this code:

ApplicationUser user = System.Web.HttpContext.Current.GetOwinContext().GetUserManager<ApplicationUserManager>().FindById(System.Web.HttpContext.Current.User.Identity.GetUserId());

You can have this in your controller or view then user with all properties will be available for you.
