Question

I have a view with a drop down, which is tied to the view model…

One of the view model’s properties:

public int selectDTypeID { get; set; }

the view has a drop down:

   Html.DropDownListFor(
       model => model.selectDTypeID , 
       new SelectList(
              new List<Object>{ 
                   new { value = 1 , text = "Test1"  },
                   new { value = 2 , text = "Test2" },
                   new { value = 3 , text = "Test3"}
                },
              "value",
              "text"
       )
    )

How can I get the the value of the drop down list on post back without using an extra parameter… I’d just like to be able to do this…

[HttpPost]
public ActionResult ContinueDonation(AddDonationViewModel model)
{
 var id = model.selectDTypeID;

}

Can I do something like this?

If your View is a strongly typed view like this,

@model AddDonationViewModel
@using (Html.BeginForm())
{
   @Html.DropDownListFor(
       model => model.selectDTypeID , 
       new SelectList(
              new List<Object>{ 
                   new { value = 1 , text = "Test1"  },
                   new { value = 2 , text = "Test2" },
                   new { value = 3 , text = "Test3"}
                },
              "value",  "text"))    

    <input type="submit" value="go" />
}

When you click on submit, the selected value will be available in the SelectdTYpeID property in your HttpPost Action method

[HttpPost]
public ActionResult ContinueDonation(AddDonationViewModel model)
{
  var id = model.selectDTypeID;  // You have your selected ID here
}
