Here is a high-level example:
@model App.YourModelName
@using(Html.BeginForm())
{
<div>
@Html.DropDownListFor(m => m.Marital_ID, Model.MaritalStatus)
</div>
<input type="button" value="Go" />
}
In your controller's action method, you can read back the selected id like this:
public ActionMethod(YourModelName yourModel)
{
return View(...);
}
Hope this helps!
