Hi Can query string be accessed in HTMLHelper extension methods. We need to render differently depending on the querystring in the request.

Yes, through the current context, which is a property on HTML Helper.

public static string DoThis(this HtmlHelper helper)
{
   string qs = helper.ViewContext.HttpContext.Request.QueryString.Get("val");
   //do something on it
}

Sure:

public static MvcHtmlString Foo(this HtmlHelper htmlHelper)
{
    var value = htmlHelper.ViewContext.HttpContext.Request["paramName"];
    ...
}

You can access the querystring via the HttpContext object. Like so...

string itemVal = System.Web.HttpContext.Current.Request.QueryString["item"];

NOTE: HttpContext.Current should be avoided in ASP.NET Core where possible
