Question

The website I am working on will contain a drop-down list that shows a number of reason codes.

Is it possible to populate a drop-down list with an array derived from a custom class?

Something like this:

ASPX Page

<asp:DropDownList ID="ddlReasonsWhy" runat="server"></asp:DropDownList>

ASPX Code Behind

protected void Page_Load(object sender, EventArgs e)
{
    //instantiate custom class
    Class1 reasonsList = new Class1();
   //populate reasons list
   this.ddlReasonsWhy.Items.Add(reasonsList.getReasons);

Custom Class

public string[] getReasons()
    {
        string[] Reasons;
        Reasons[0] = "test";
        Reasons[1] = "test2";
        Reasons[2] = "test3";

        return Reasons;
    }

UPDATE1:

Thanks to the answers and this stack link my final solution is similar to Ahmet and silky answers.

Class

 public List<ListItem> getRejectReasons()
    {
        List<ListItem> reasons = new List<ListItem>();
        reasons.Add(new ListItem("Select Value", "0"));
        reasons.Add(new ListItem("Red", "1"));
        reasons.Add(new ListItem("Green", "2"));
        return reasons;

    }

Code Behind

 //instantiate custom class
 Class1 reject = new Class1();
 this.ddlReasonsWhy.DataSource = reject.getRejectReasons();
 this.ddlReasonsWhy.DataBind();

Answer 1

Use ListItem instead of string and Addrange for Add

edit: getReasons is not a variable so use getReasons()

ASPXPAGE

<asp:DropDownList ID="ddlReasonsWhy" runat="server"></asp:DropDownList>

ASPX Code Behind

protected void Page_Load(object sender, EventArgs e)
{
    //instantiate custom class
    Class1 reasonsList = new Class1();
   //populate reasons list
   this.ddlReasonsWhy.Items.AddRange(reasonsList.getReasons());
}

Custom Class

public ListItem[] getReasons()
    {
        ListItem[] Reasons;
        Reasons[0] = "test";
        Reasons[1] = "test2";
        Reasons[2] = "test3";

        return Reasons;
    }
