Question

I am trying to access the Route value of id from inside the PartialView. I have a Post, Comments scenario. And I want my Comments partialview to have access to the PostId.

The Url looks like the following:

Posts/Detail/2

Now, how can I access the value 2 inside the Partial View?

UPDATE:

I changed my CommentsController to the following:

 public ActionResult Add(string id,string subject,string name,string body)
{

}

But now when I debug it does not even step into the Add method.

UPDATE 2:

My partial view looks like the following:

<div class="title">Add Comment</div>

@using (Html.BeginForm("Add","Comments",FormMethod.Post))
{
    @Html.Label("Subject") 
    @Html.TextBox("subject")
    <br />
    @Html.Label("Name") 
    @Html.TextBox("name") 
    <br />
    @Html.Label("Body") 
    @Html.TextBox("body") 




    <input type="submit" value="submit" />                            
}

And here is the Controller:

 public ActionResult Add(string id, string subject, string name, string body)

If I remove id from the above controller action then it works.

You could fetch it from RouteData:

In WebForms:

<% 
    var id = ViewContext.RouteData.Values["id"];
%>

In Razor:

@{
    var id = ViewContext.RouteData.Values["id"];
}

After showing your code it seems that in your form you are not passing the id. So modify it like this:

@using (Html.BeginForm("Add", "Comments", new { id = ViewContext.RouteData.Values["id"] }, FormMethod.Post))
{
    ...
}

or use a hidden field if you prefer:

@using (Html.BeginForm("Add", "Comments", FormMethod.Post))
{
    @Html.Hidden("id", ViewContext.RouteData.Values["id"])
    ...
}

Now you should get the id in your Add controller action.
