ASP.NET MVC route for serverside imagemap

Question

I've got an <input type='image'> in an ASP.NET MVC view, but I'm not sure how to retrieve the coordinates in the action that runs when the form is submitted. The requested URL looks like

/Map/View/?map.x=156&map.y=196

but I can't just do

public ActionResult View( int map.x, int map.y )
{
  ...
}

because they're obviously not valid names for C# method parameters. Is there any equivalent of the ActionName attribute to map query parameters to method parameters?

You have to use use Model binder and set the prefix property to "map":

First create the Model object:

public class ImageMap()
{
  public int x{get;set;}
  public int y{get;set;}
}

And in your action method:

public ActionResult About([Bind(Prefix="map")]ImageMap map)
{

   // do whatever you want here
    var xCord = map.x;

}
