public class QueryStringConstraint : IRouteConstraint
{
public QueryStringConstraint(string value, bool ignoreCase = true)
{
Value = value;
IgnoreCase = ignoreCase;
}
public string Value { get; private set; }
public bool IgnoreCase { get; private set; }
public virtual bool Match(HttpContextBase httpContext, Route route, string parameterName, RouteValueDictionary values, RouteDirection routeDirection)
{
var currentValue = httpContext.Request.QueryString[parameterName];
return IgnoreCase ? currentValue.ToLowerInvariant() == Value.ToLowerInvariant() : currentValue == Value;
}
}
routes.MapRoute("Create page details", "Product/Create",
new { controller = "Product", action = "CreateDetails" },
new { page = new QueryStringConstraint("details") });
Alternatively if you have different models for those actions, you could do something like this (with standard "{controller}/{action}/{optional id}" route):
public class RequireRequestValueAttribute : ActionMethodSelectorAttribute
{
public RequireRequestValueAttribute(string name, string value = null, bool ignoreCase = true)
{
Name = name;
Value = value;
IgnoreCase = ignoreCase;
}
public string Name { get; private set; }
public string Value { get; private set; }
public bool IgnoreCase { get; private set; }
public override bool IsValidForRequest(ControllerContext controllerContext, MethodInfo methodInfo)
{
var value = controllerContext.HttpContext.Request[Name];
return value != null && (Value == null || (IgnoreCase ? Value.ToLowerInvariant() == value.ToLowerInvariant() : Value == value));
}
}
[RequireRequestValue("Page", "Detail")]
public ActionResult Create(ProductDetailModel model)
{
return View(model);
}
[RequireRequestValue("Page", "Overview")]
public ActionResult Create(ProductOverviewModel model)
{
return View(model);
}

An action name cannot contain a question mark. The question mark is a reserved character in a URL indicating the beginning of the query string.

What if you not create another action? Just call your "Create" action with the query string.
http://localhost/Home/Create?Page=Details
public ActionResult Create()
{
var page = Request.QueryString["Page"];
// do your stuff, or redirect here if you like
// return RedirectToAction("Create" + page);
return View();
}
