How to populate dropdown in mvc

I have a dropdown list and i am trying to populate my dorpdown list with the data from the database, for this i am using mvc so how do i write a method in controller and how do i write the jquery for that: This is what i implemented in my view;

@Html.DropDownListFor("")

This is what i can find for jquery:

$(document).ready(function() 
{ 
    $('#id_trial').click(function() {

alert("entered in trial button code");

$.ajax({
    type: "GET",
    source: "/ClassName/MethodName",
    dataType: "json",
    success: function (data) {
        $.each(data.aaData,function(i,data)
        {
         alert(data.value+":"+data.text);
         var div_data="<option value="+data.value+">"+data.text+"</option>";
        alert(div_data);
        $(div_data).appendTo('#ch_user1'); 
        });  
        }
  });
});
});

This is what i think might be a method in a controller:

public virtual JsonResult MethodName()
    {
        IList<Fund> funds = _fundManager.Search();
        var list = from x in funds
        select new { Id = x.Code, Name = x.Name };  
        return Json(list);
    }

I dont know how to link all of them and make it work, ant help will be appreciated.

Just try below. See this example given by Darin Dimitrov. 

@model App.Models.staff

@Html.DropDownListFor(
    x => x.staffName, 
    Enumerable.Empty<SelectListItem>(), 
    "-- Loading Values --",
    new { id = "foo" }) 

 $(function () {
        $.getJSON('/ClassName/MethodName', function (result) {
            var ddl = $('#foo');
            ddl.empty();
            $(result).each(function () {
                $(document.createElement('option'))
                    .attr('value', this.stafdid)
                    .text(this.staffName)
                    .appendTo(ddl);
            });
        });
    });

Try to do something like this:

$.ajax({
type: "GET",
source: "/ClassName/MethodName",
dataType: "json",
success: function (data) {
   var div_data="";
    $(data).each(function(){
     div_data +="<option value="+$(this).value+">"+$(this).text+"</option>";
    });
    $('#ch_user1').html(div_data);
   }
 });

Can refer to following code snip or detail article on following link

Dynamically populate the drop-down using jQuery in ASP.Net MVC3

In your controller:

[HttpGet]
public virtual JsonResult LoadInfo()
{
    var query = _repository.GetInformation(); //Here you return the data. 
    return Json(query, JsonRequestBehavior.AllowGet);
}

Then in your view:

Then you load the drop down using jQuery

function LoadInfo() {

    $.getJSON("@Url.Action(MVC.ControllerName.MethodName())", null,
        function (data) {

             $("#info").empty();

            $.each(data, function () {
                 $("#info").append($("<option />").val(this.Id).text(this.Name));
            });

    });
}

The code you have shown should work with a simple change-

@Html.DropDownList("ch_user1");
