Question

I have the following UserController methods:

public ActionResult DeleteThread(int RootMessageID)
{
    _repository.DeleteMessageThread(RootMessageID);
    return RedirectToAction("ActionMessageSuccess", new { txt = "Message was sent successfully" });
}
    public ActionResult ActionMessageSuccess(string txt)
    {
        return View(txt);
    }

have cshtml page (in Views\User):

@model System.String
@{
    ViewBag.Title = "SendMessageSuccess";
    Layout = "~/Views/Shared/_LayoutUser.cshtml";
}

<h2>@Model</h2>

but I got:

The view 'Message was sent successfully' or its master was not found or no view engine supports the searched locations. The following locations were searched:
~/Views/User/Message was sent successfully.aspx
~/Views/User/Message was sent successfully.ascx
~/Views/Shared/Message was sent successfully.aspx
~/Views/Shared/Message was sent successfully.ascx
~/Views/User/Message was sent successfully.cshtml
~/Views/User/Message was sent successfully.vbhtml
~/Views/Shared/Message was sent successfully.cshtml
~/Views/Shared/Message was sent successfully.vbhtml

after call DeleteThread. Why?

There is no problem with redirectToAction.

You are calling RedirectToAction("ActionMessageSuccess", new { txt = "Message was sent successfully" });

So it redirected to action ActionMessageSuccess with txt value.

With in ActionMessageSuccess you are returning a view with name txt i.e. “Message was sent successfully“, but system unable to file a view with name “Message was sent successfully”.
