Make sure you bind the data after adding items to DropDownlist as:ddldriver.DataBind();

ddldriver.Items.Clear();
        for (int i = 0; i < assigneddriver.Count; i++)
        {
          // add items  
        }
// now bind the Data to the Dropdownlist   
ddldriver.DataBind();

Check also if assigneddriver list is not null.
