I am binding an MVC dropodown and filtering a list from the selected value of dropdown.
However the selected value is not being retained on postback.
I have an index view and the controller initially loads a full list. I then have an index "post" method
that takes the selected ID from dropdown to filter the list.
The dropdown list is wrapped inside a form post tag like this
<% using (Html.BeginForm("Index", "customers", FormMethod.Post, null))
Is this the correct approach? I am sure it is something to do with postback
