DropDownListFor does not select value if in for loop

Question

In my view

<%= Html.DropDownListFor( x => x.Countries[ i ], Model.CountryList )%>

in my controller

public int[ ] C         


        

Answer 1

A select box sends a single value, so the Countries property should not be an array. Also in your post it is not clear where's the i variable you are using in your lambda expression coming from and this x.CountryList used in the helper won't compile as x is not defined.

Model:

public class MyModel
{
    public int SelectedCountry { get; set; }
    public List CountryList { get; set; }
}

View:

<%= Html.DropDownListFor(x => x.SelectedCountry, Model.CountryList) %>

UPDATE:

According to the comment it seems that there are multiple drop downs. I suspect that the problem might come from the i variable used as index in a for loop.

You might try this instead:

Model:

public class MyModel
{
    public int[] Countries { get; set; }
    public List CountryList { get; set; }
}

View:

<% foreach (var country in Model.Countries) { %>
    <%= Html.DropDownListFor(x => country, Model.CountryList) %>
<% } %>
