This package adds Rails-like flash functionality to your MVC controllers, backed by the excellent Toastr JavaScript notification library. Flash notifications are persisted through redirects and are removed when shown.

Best way to install is via NuGet:

PM> Install-Package RedWillow.MvcToastrFlash

This package has the following NuGet dependencies:

• Microsoft.AspNet.Mvc, version >= 3.0.20105.1
• toastr, version >= 2.1.1

First, follow the steps required to get Toastr up and working: https://www.nuget.org/packages/toastr

At the top of your layouts pages, or views that don't use layouts (that you want Toastr notifications to appear on) add:

@using RedWillow.MvcToastrFlash

And following the @RenderSection("scripts", required: false) near the bottom add (should be right before the closing body tag):

@Html.ToastrNotifications()

Add this using statement:

using RedWillow.MvcToastrFlash;

Then, flash notifications to your heart's content:

public ActionResult Index()
{
    this.Flash(Toastr.SUCCESS, "Welcome!", "Glad you arrived safely.");

    return View();
}

See the Sample project for more usage examples.
