C#

public ViewResult Index()
{
    var categories = from c in db.category_master select c;
    ViewData["Categories"] = new SelectList(categories, "ID", "Name");
    return View(db.akshay_category_master.ToList());

}

HTML

// In view 

@Html.DropDownList("Categories", ViewBag.applicationList as SelectList, "Select", new { onchange = "javascript:sendParam();" })

//Javascript Function 

<script type="text/javascript">
function sendParam() {

window.location = "Category/CategoryDetails/" + jQuery("#Categories").val();

}

C#

// that Method in Controller

public ViewResult CategoryDetails(int id)
{

    var Result = from C in db.category_master
                 where C.id == id
                 select C;
    return View("CategoryDetails", Result.ToList());
  
}
