How do I create the correct route values for this ActionLink?

Question

The Model of SearchResults.aspx is an instance of PersonSearch; when the request for a new page arrive (a GET request), the action method should take i

Answer 1

If you are using Razor (I realize OP asked four years ago before Razor was invented, but people finding this maybe using it).

I was able to get something working by using an inline @helper method.

@helper RunnerLink(PersonSearch model, int page)
{
    var routeParms =new RouteValueDictionary(model.GetType().GetProperties().ToDictionary(p => p.Name, p => p.GetValue(model, null)));
    routeParms.Add("page", page.ToString());
    routeParms.Add("Controller", "Property");
    @Html.ActionLink("Search", "Index", routeParms)
}

Usage would be simple --

@RunnerLink(myPersonSearchInstance, 1)

It isn't the most elegant solution, but it works well if you want to pass an object in as a routeValue, but you need to pass additional items, such as Controller, Area or in OPs case page.

Answer 2

It think it would be better to create another object with the correct values, instead of using (and potentially altering the current routevalues):

<%=Html.ActionLink("Next Page >", "SearchResults", new {
    search = this.Model,
    page = 1 //or whatever
}) %>

Answer 3

You need to override ToString().

Answer 4

You need use RouteLink instead ActionLink. Your code should look something like this

@Html.RouteLink("Next", new {controller = "SearchResults", action = "Index", search=samevalue, page=1 })

I love that he included test cases!
