Add dropdownlist with datatextfield and datavaluefield property in aspx page

<asp:DropDownList runat="server" ID="ddlCity" DataTextField="CityName" DataValueField="CityID"></asp:DropDownList>

Bind dropdownlist in page load inside !IsPostBack

C#

if (!IsPostBack)
            {
                //Bind Datatable to dropdownlist datasource property (probably in page_load inside !IsPostBack)
                //e.g datatable contain column CityID , CityName
                ddlCity.DataSource = GetCities();
                ddlCity.DataBind();

            }

access ID and name field using below code

C#

//get selected city ID
           string cityName = ddlCity.SelectedItem.Text;
           //get selected city ID
           int cityID = Convert.ToInt32( ddlCity.SelectedItem.Value);

This will serve your purpose if your data comes from datatable

Hi Shanavaz,
When you fill your dropdownlist set its DataTextField and
DataValueField. In DataTextField bind Company Name, in DataValueField bind Company Id and while saving save its DataValueField.
