how to get disabled dropdownListFor Value in controller

I have a dropdownListFor controls which are cascade in nature on edit i do need to disabled the below cascaded dropdown lists until the values get changed from the first one , so below is my code of dropdown list

```

@Html.LabelFor(model => model.Program_Id, "Program_Id", htmlAttributes: new { @class = "control-label col-md-2" })

@Html.DropDownList("Program_Id", null, htmlAttributes: new { @class = "form-control", @id = "ddlPrograms" })

@Html.ValidationMessageFor(model => model.Program_Id, "", new { @class = "text-danger" })

```

I am making them disable using javascript

```

document.getElementById("ddlYear").disabled = true;

document.getElementById("ddlBlocks").disabled = true;

document.getElementById("ddlModules").disabled = true;

```

But on Edit when I submit the forms instead of selected value they send 0 to the controller . how to fix that issue if i am using hidden field then how i would be able to access this hidden field value as i am using entity framework and below is my controller edit post method

```

public async Task Edit([Bind(Include = "Course_Id,Course_Name,Course_Code,Course_Visibility,Course_Start_Date,Course_End_Date,Block_Id,Module_Id,Program_Id,Year,Course_Description,Course_Image,Course_Category_Id,Course_Content_File_Path,Course_announcement,Course_Tags,Status,Course_Short_Name,Date_Created,Date_Modified")] Courses courses)

{

if (ModelState.IsValid)

{

db.Entry(courses).State = EntityState.Modified;

if (db.SaveChanges() > 0)

{

TempData["UpdatedMessage"] = "Updated Successfully";

}

// await db.SaveChangesAsync();

return RedirectToAction("Index");

}

ViewBag.Block_Id = new SelectList(db.Blocks, "Id", "Name", courses.Block_Id);

ViewBag.Course_Category_Id = new SelectList(db.Courses_Category, "Id", "Category_Name", courses.Course_Category_Id);

ViewBag.Module_Id = new SelectList(db.Moduels, "Id", "Name", courses.Module_Id);

ViewBag.Program_Id = new SelectList(db.Programs, "Id", "Program_Title", courses.Program_Id);

ViewBag.Year = new SelectList(db.Years, "Id", "Name", courses.Year);

return View(courses);

}

```

Thanks in advance

class SelectList
{
public string Modules {get;set;}
public int id {get;set;}
public string name {get;set;}
public int Module_Id {get;set;}
}
List ObjList = new List();
var obj1 = new SelectList();
obj1.Moduels = "modeules";
obj1.Id = 1
obj1.Name = "abd";
obj1.Module_Id = 1l
ObjList .add(new SelectList { Text = "Latur", Value = "1" });
{
,
new SelectListItem { Text = "Pune", Value = "2" },
new SelectListItem { Text = "Mumbai", Value = "3" },
new SelectListItem { Text = "Delhi", Value = "4" },
};
//Assigning generic list to ViewBag
ViewBag.Locations = ObjList;
@Html.DropDownList("ObjList", (IEnumerable)ViewBag.Module_Id , new { id = "ddlModules", @class = "form-control" })
