What do you mean by "dialog views"? I don't recognise this as a known technical term. Do you just mean a regular "view"?
If so, then you specify the model you want to use in the view like this (usually as the first line in the cshtml file):
@model BidWheels.Data.Dealers
That will provide you an instance of the Dealers class, but looks like you want a list. So you probably want to create a new view model class with a dealers list:
public class DealersViewModel
{
public List<Dealers> Dealers { get; set; };
}
Then in your view:
@model BidWheels.Data.DealersViewModel
...
@{
foreach(var item in Model.Dealers)
{
<span>@item.DealershipName</span>
}
}
You also need to pass the model instance to the view in your controller:
public ActionResult MyDealers()
{
var model = new DealersViewModel();
model.Dealers = new List<Dealers>();
return View(model);
}
