How to check TempData value in my view after a form post?

asp.net-mvc, if-statement, tempdata, view

Solution

Please try this

var tempval = TempData["var"];

then write your if statement as follow

@if (tempval.ToString() == "abcd") 
{
    <span>Check</span> //Never displayed
}
else
{
    <span>@tempval</span>; // Display "abcd"
}

Problem

I fill my TempData from a `FormCollection` and then I try to check the value of my `TempData` in my view with MVC 4 but my `if` statement isn't working as I expect. Here is my code. Controller : ``` [HttpPost] public ActionResult TestForm(FormCollection data) { TempData["username"] = data["var"].ToString(); //data["var"] == "abcd" return RedirectToAction("Index"); } ``` View: ``` @if (TempData["var"] == "abcd") { <span>Check</span> //Never displayed } else { @TempData["var"]; // Display "abcd" } ``` This looks like really simple and I don't understand why I can't display this `Check`. Can you help me ?
