Question

I would like to return error html text with “IsError” flag.
How could I implement it?
Here is my trial.
Assuming that I submitted the Ajax.BeginForm and error occured on server side.

Global.asax

void Application_Error(Object sender, EventArgs e)
{
    var exception = Server.GetLastError();
    var number = GetErrorNumber();
    Server.ClearError();
    Response.Redirect("/Error?number=" + number, false);
}

View Error/index

<div>
An error occurred<br>
Error number : @ViewBag.ErrorNumber
</div>

ErrorController I want to return JSON including view html and “IsError = true”!!

ViewBag.ErrorNumber = number;
return View();

Client side JavaScript catches the returned value.
And the returned html text would renders if “IsError” was true.(I wish)

I think you should return json and create the HTML DIV on client side using javascript. I think you can not return HTML in json.
