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

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)
{
   ...
}

You could use javascript to detect a click on the link, serialize the form (or whatever data you want to pass) and append it to your request parameters. This should achieve what you're looking to achieve...

No, you cannot pass entire complex objects with links or forms. You have a couple of possible approaches that you could take:

  • Include each individual property of the object as query string parameters (or input fields if you are using a form) so that the default model binder is able to reconstruct the object back in the controller action
  • Pass only an id as query string parameter (or input field if you are using a form) and have the controller action use this id to retrieve the actual object from some data store
  • Use session
