Question

I’ve got a common layout page for views. This layout page contains a dropdown list, which shows the list of available dates. What I want is to reload this page having changed the data param only. The controller, action and any other params should be somehow taken from the current request context.

If I wanted to do it manually on every view, I’d say it would be equal to

@Html.ActionLink(
     "",                                        
     "I need to have current action name here", 
     new { date = "The Value of the chosen SelectListItem" });

How can I achieve this? Or is there any different approach?

Information about current action is available in RequestContext, you could access it directly:

@Url.Action(ViewContext.RequestContext.RouteData.Values["action"], 
         new { date = "The Value of the chosen SelectListItem" });

In your case I would add the url to option data attribute and then work with it with jQuery:

$('select#yourid').change(function() {
    document.location.href = $(this).find('option:selected').data('url'));
});​
