Assign Attribute to @Html.DropdownList

Question

I want to assign some ID attribute name to my Dropdown list which is using data from the ViewBag as,

ViewBag.Group = new SelectList(group, "GroupId", "Name");

and in the View side I have used Razor syntax for showing the Dropdown as,

@Html.DropDownList("Group", "New", new { id="testID" } )

But I am getting the error on this line. Can I just assign ID of This Razor syntax? I know that the ID is generated with the Name "Playlist" But I am having 2 different dropdowns using same ViewBag. Because of that I have to assign different "ID" attribute value for them. How can it be done?

Answer 1

You should be using something like this

@Html.DropDownList("Group",null,new{@id="testID"});

because the data for the DropDownList comes from the ViewBag to name Group

can I assign some Default value in This Like I have assigned in My question as "New"?? – Clarence

@RahulRJ: yes it is an optionlabel that you can very well set. – Natalyanataniel

But how can I set it Here if I want my default value as "New" in my Dropdown – Clarence

Yes, how can I have the dropdownlist have an initial blank string at the beginning of the list? – Nagging

Just set the option label as empty string or some content, it will be shown if none is selected – Natalyanataniel

Answer 2

Try it:

In controller

  ViewBag.EmployeeId = new SelectList(db.tb_employees, "id", "last_name");

In View

@Html.DropDownList("EmployeeId", (IEnumerable<SelectListItem>)ViewBag.EmployeeId,"Show All", new { @class = "form-control" })
