Load all data to DropDownList

Question

I have this code below working fine.

Sample output

Computer Department

Technical Department

Product Department

Let say my department is Product Department. I am the the who log-in in the system / project. It is possible to first load my department in the DropDownList?. What I mean in first load is upon loading of the dropdown my department is set to be the first.

Controller

ViewBag.DepartmentId = new SelectList(db.Departments, "DepartmentId", "DepartmentDesc", null).OrderBy(m => m.Text);

HTML

@Html.DropDownList("DepartmentId ", ViewData["DepartmentId "] as SelectList, "", new { @style = "width:130px;" })

Just set the value of property`DepartmentId` in the GET method before you pass the model in the view, and that option will be selected — , Jan 20 '17 at 07:57

Note also that you cannot use the same name for the property your binding to and the SelectList (refer [this answer](http://stackoverflow.com/questions/37161202/will-there-be-any-conflict-if-i-specify-the-viewbag-name-to-be-equal-to-the-mode/37162557#37162557)) - rename the `ViewData` property to say `DepartmentList` — , Jan 20 '17 at 08:03
@StephenMuecke Just want to ask. How did you get the `Model.TipoviDepozita`?. Refer to your first link. and what is `"NotAModelProperty", `? — KiRa, Jan 20 '17 at 08:06
Not sure what you mean (thats is OP's data) - but you need `ViewBag.DepartmentList = new SelectList(db.Departments.Orderby(x => x.DepartmentDesc), "DepartmentId", "DepartmentDesc");` - or better use a view model — , Jan 20 '17 at 08:10

Where you set null in new SelectList, set your selected option.

ViewBag.DepartmentId = new SelectList(db.Departments.OrderBy(m => m.Text), "DepartmentId", "DepartmentDesc", selectedDepartmentId);

Try this code:-

ViewBag.DepartmentId = new SelectList(db.Departments, "DepartmentId", "DepartmentDesc",SelectedDepartmentId).OrderBy(m => m.Text);

And

@Html.DropDownList("DepartmentId ", ViewData["DepartmentId "] as SelectList, "My Department", new { @style = "width:130px;" })
