Here's a little method I built that worked on the site I was accessing... hopefully it will help someone :)

    private string GetDDLValueByName(HtmlDocument doc, string Name)
    {
        string Value = "";
        HtmlElementCollection selects = GetElementCollectionFromDocument(webBrowser1.Document, "SELECT");
        if (selects != null)
        {
            foreach (HtmlElement select in selects)
            {
                if (select.Name == Name)
                {
                    HtmlElementCollection children = select.Children;
                    if (children.Count > 0)
                    {
                        foreach (HtmlElement child in children)
                        {
                            if (child.OuterHtml.Contains("selected"))
                                return child.InnerText;
                        }
                    }
                    else
                        return "";
                }
            }
        }
        return Value;
    }

Use following code: Request.Form[ddl.UniqueID]

The code above allows to get value of selected option.

It depends on how you are populating the DropDownList. If you are using a DataSet, you should be doing something similar to this:

DataSet ds = yourProcedureToGetDataSet();
yourDropDownList.DataTextField = ds.Tables[0].Columns["name"].Caption;
yourDropDownList.DataValueField = ds.Tables[0].Columns["id"].Caption;
yourDropDownList.DataSource = ds;
yourDropDownList.DataBind();
yourDropDownList.Items.Insert(0, new ListItem("Select a whatever", "-1"));

Then you can read the selected value:

int i = int.Parse(yourDropDownList.SelectedValue);

Hope this helps.
