How to modify HTTP Response Using Filters in MVC 3 Razor? - asp.net-mvc-3

Question

HtML section in _Layout.cshtml
<div id="header">
<div class="logo"><img src="#Url.Content("~/!(IMAGEPATH)!/logo.png")" alt="" /></div>
<div class="fb_like"><img src="#Url.Content("~/!(IMAGEPATH)!/fb_like_btn.png")" alt="" /></div>
<div class="google_plus"><img src="#Url.Content("~/!(IMAGEPATH)!/google_plus.png")" alt="" /></div>
<div class="header_rt">
<ul>
<li>Call us: 1500 258 789</li>
<li>Live chat</li>
<li>My Account</li>
<li>Sign in</li>
</ul>
<div class="search">
<input type="text" value="Type your keyword..." class="srh_txt" />
<input name="Submit" type="submit" value="Submit" class="srh_btn" />
</div>
</div>
</div>
<div id="main">
#RenderBody()
</div>
Html section in Index.cshtml
#{
ViewBag.Title = "Home Page";
}
<div class="clr"></div>
<div id="banner">
<div id="slider"><img src="#Url.Content("~/!(IMAGEPATH)!/banner.jpg")" alt="" /></div>
<div class="banner_rt">
<div class="adv1"><img src="#Url.Content("~/!(IMAGEPATH)!/adv1.jpg")" alt="" /></div>
<div class="adv2"><img src="#Url.Content("~/!(IMAGEPATH)!/adv2.jpg")" alt="" /></div>
</div>
Using bellow code I able to Replace !(IMAGEPATH)! only in _Layout.cshtml
void Application_PostReleaseRequestState(object sender,EventArgs e)
{
if(string.CompareOrdinal(Response.ContentType,"text/html") == 0)
{
Response.Filter = new ResponseFilter(Response.Filter);
}
}
But above described code not affecting child pages like Index.cshtml. Please tell me any event in ASP.NET MVC3 like old protected override void OnPreInit(EventArgs e) of Classic ASP.NET !!!!
I want to know which event effecting all the child pages before rendering in MVC3 ?

Answer 1

Within Base Controller, write the bellow code
protected override void OnResultExecuting(ResultExecutingContext filterContext)
{
var response = filterContext.HttpContext.Response;
if (string.CompareOrdinal(response.ContentType, "text/html") == 0)
{
response.Filter = new ResponseFilter(response.Filter);
}
base.OnResultExecuting(filterContext);
}
