How can I pass HTML code stored in a string variable to a view in MVC 5?
I have an action which is defined like this one:
public ActionResult TempOutput(string model)
{
return View((object)model);
}
I also have its view, which is defined like this:
@model String
@{
ViewBag.Title = "TempOutput";
}
<h2>TempOutput</h2>
@Model
And, at one point in my code, I call the action method and the view with this line of code:
return RedirectToAction("TempOutput", "SEO", new { model = tmpOutput });
The point is that, it works all fine when I have a short string, but in my case tmpOutput is a string variable which holds a long HTML code. The thing is that I want to pass that HTML code inside my view, but I don't want it to be displayed as a normal text, but I want it to be parsed as a HTML code and change the view. Currently, when I run the code, I get an error message saying:
The request filtering module is configured to deny a request where the query string is too long.
How can I solve the problem?
The problem in your case is that redirecttoaction makes a new (302) http request and your 'model' which you are sending will be send with querystring and querystring has a limit then instead try using TempData as:
TempData["mydata"] = tmpOutput ;
and then retrieve TempData value in TempOutput action or directly use it in View as shown.
View :
<div>@Html.Raw(TempData["mydata"])</div>
