In a asp.net form, we have an asp:DropDownList component, Upon click on button btnSave, we hope that the selected value is used to save the users choice, but the SelectedValue property is always...

public partial class ThePage : System.Web.UI.Page
{
     protected void Page_Load(object sender, EventArgs e)
     {
           FillDdlOptions();
     }

     private void FillDdlOptions()
     {
           ddlOptions.Items.Clear();
           ddlOptions.Items.Add(new ListItem("Pick one...", string.Empty)); 
           ddlOptions.Items.Add(new ListItem("Option A", "a"));
           ddlOptions.Items.Add(new ListItem("Option B", "b")); 
           ddlOptions.Items.Add(new ListItem("Option C", "c"));
     }

     protected void btnSave_Click(object sender, EventArgs e)
     {
           Response.Write(ddlOptions.SelectedValue);
     }
}
