                    </tr>

                </table>



Here is my code behind

C#
protected void AddElection_Click(object sender, EventArgs e)
   {
       string estart = Request.Form["dt1"];
       string eend = Request.Form["dt2"];
       string pstart = Request.Form["pt1"];
       string pend = Request.Form["pt2"];





       NewElection elec = new NewElection(txtElectionName.Text, Request["estart"].ToString(), Request["eend"].ToString(), Request["pstart"].ToString(), Request["pend"].ToString());
       elections.AddElections(elec);
       Label1.Text = "Thank you for adding an election.";


   }

You should provide name attribute to the control for getting values by using Request.Form[].For example
C#
<input type="text">name="dt1" id="dt1" /> string estart = Request.Form["dt1"];</input>

Hope this helps
