Select a default value in dropdownlistfor MVC 4

Question

I'm trying to make a dropdownlistfor with a selected value but it doesn't work :/ And I search on the web but I don't find the solution :/ For the moment, I'm doing this : In C# : ``` ViewBag.ID_VEH = new SelectList(db.VEHI, "ID_VEH", "COD_VEH", 4); // 4 is an example ``` In my cshtml : ``` @Html.DropDownListFor(model => model.ID_VEH, ViewBag.ID_VEH as SelectList) ``` The dropdownlist is well complete but the default value is not selected :/ do you have an idea please ?

Accepted Answer

What I like to do is add a list of the items to display in the dropdownlist to my model, so I don't have to pass that list via a viewbag. Also i like to add a field to my model that contains the SelectedValue, that I fill in the controller

Then you can do

```
@Html.DropDownListFor(model => model.ID_VEH, new SelectList(Model.listVEH, "ID_VEH", "COD_VEH", Model.SelectedVEH_ID), "--Select VEH--")
```
