//create a method to get Dropdown values 

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());

        }

// 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();

    }

  // 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());
          
        }

Solution 2

try to apply this example.

C#

@Html.DropDownList(
    "PropertyTypePropertyTypeId",
     ViewData["Categories"], // it need to be casted  i think 
    null,
    new { onchange = "document.location.href = '/Controller/MyAction?country=' + this.options[this.selectedIndex].value;" })

you have to create an action in the controller.

SQL

public ActionResult MyAction(string country ) 
            {
                 // return the adequate view depending on the country argument 
                  .....
            }

and good luck.

Thank u 4 ur reply...while executing my project with this coding the error message is showing like this.. The name 'listitems' does not exist in the current context.. Can u help me

you have to use your own list of items. what you have in the ViewData["Categories"] i think.
I just give you an idea.

Is MyAction is a controller page(ie .cs page) or function name??? i have a controller page called PropertyMainController.cs and while running my url is http://localhost:50888/Controller/PropertyMainController.cs?country=1. am getting id but error message is showing like this
The resource cannot be found.

Thank you so much sir... it is working nice.

MyAction is the function name in the controller like i said

also if all things are well done
you have to use this URL

http://localhost:50888/PropertyMainController/MyAction?country=1

without the .cs

i see that you still don't understand the basics of routing in MVC.net

so i advaice you to see this link
