How to get Select2 value from asp.net code behind

I have Dropdownlist that has only one element:

<asp:DropDownList CssClass="select2" ID="ddl" runat="server" />

protected void Page_Load(object sender, EventArgs e)
{
    if (!Page.IsPostBack)
    {
        ddl.Items.Add(new ListItem("text", "value"));
    }
}

Also my ddl gets data from ajax call. When I'm trying to get changed value from code behind it still returns value of first element.

 string value = ddl.SelectedValue; //I got data from ajax call, changed value but it still returns first "value"

But from javascript I can get changed value, so now on every change in my ddl I copy value to hidden field so I can get value from codebehind

$("#ddl").change(function () {
   $('#hidden_for_ddl').val($("#ddl").val());
});

Finally I can get selected value from code, is it easier way to solve my problem?

string value = hidden_for_ddl.Value; //returns "selected value"

string value = Empty.String;
foreach (ListItem item in ddl) {
    if ((item.Selected == true)) {
value = item.Value;
return;
    }
}

This will go through each item and set the string value when it finds one that is selected.
