I'm new one for MVC.

I have a two tables in my database call 'company' and 'Department'
So One company has many Department.

In my project I add my data base to Model as ADO.net Entity Model.
I create primary key and Forging key.
So when I create a new Department I want to show the company list in the drop down list.

I don't know how to do it?

I try like this

```
   @Html.DropDownListFor(model => model.tblCompany.PKComID, Model.tblCompany)

```

but It it not working
How can I do it?
