Implementing Add New Product (Part 3 - Using HTML Helpers for Drop Down Lists)

The product entry screen we created in the previous section works, but isn't very user friendly.  Specifically, it requires that the end user know the raw CategoryID and SupplierID numbers for the Product being entered.  We need to fix this by instead displaying an HTML dropdownlist that displays the human readable names.

Our first step will be to modify our ProductsController to pass to the View two collections - one containing a list of available categories, the other a list of available suppliers.  We'll do this by creating a strongly typed ProductsNewViewData class that encapsulates these, and which we'll then pass to the View (you can learn about this in Part 3):

Figure 19

We'll then update our "New" action method to populate these collections and pass them as the ViewData for the "New" view:

Figure 20

Within our view we can then use these collections to generate HTML <select> dropdowns.

Hi,
I'm a newbie as if you don't hear that all day long.

I have setup a project that is to allow me to post information to a SQL database, and view the updated information. I can view just fine, however I'm stuck on where in my code to add the Create, and New Methods. If you would like to look at my code I can post it or email it.

Thank you,

Casey,
