Question

I’ve got an MVC application with basic view:

myapp.com/category

and a switcher to second one:

myapp.com/category/list

App is used as independent one and as also in other application into iframe where src is: myapp.com/category. I want do not show page header when it is used into iframe, how can I achieve it? I was trying to add querystring, myapp.com/category?show=false, and set this as iframe src, but when I switch to the second view the parameter is not passed.

You could create a helper method to construct URLs that would keep the show parameter in place. For example:

public static string GetModifiedUrl(this UrlHelper helper, string url)
{
    string qstring = helper.RequestContext.HttpContext.Request.QueryString["show"];
    if (!string.IsNullOrEmpty(qstring)) url += "?show=" + qstring;
    return url;
}

Then in the views, for example:

<a href='@Url.GetModifiedUrl(Url.Action("Index", "Home"))'>Home</a>

Another option is to create add a value to the session on the first request, and use that instead. Ie, put some logic in the controller like this:

var qs = Request.QueryString["show"];
if (!string.IsNullOrEmpty(qs)) 
{
    Session["show"] = qs;
}

Then in the views, use @Session["show"] instead of @Request.QueryString["show"] to decide whether you show the header.
