Is there any way to pass a whole model via html.actionlink in ASP.NET MVC 3?

Question

How do I pass a whole model via html.actionlink or using any other method except form submission? Is there any way or tips for it?

Though it's not advisable in complex cases, you can still do that!

public class QueryViewModel
{
  public string Search { get; set; }
  public string Category { get; set; }
  public int Page { get; set; }
}

// just for testing
@{
   var queryViewModel = new QueryViewModel
   {
      Search = "routing",
      Category = "mvc",
      Page = 23
   };
}

@Html.ActionLink("Looking for something", "SearchAction", "SearchController"
                  queryViewModel, null);

This will generate an action link with href like this,

/SearchController/SearchAction?Search=routing&Category=mvc&Page=23

Here will be your action,

public ViewResult SearchAction(QueryViewModel query)
{
   ...
}
