title: About inserting record into dynamically created gridview in asp.net c#
body: <p>I have created gridview dynamically on click event of button.I have 4 fields per row(First name,last name, relation,DOB) with link button for add(lnkadd).I used Itemtemplate, edittemplate, EditItemTemplate, FooterTemplate to design gridview. 
  I used function to add rows to gridview in lnkadd click event as follows:</p>
  
  <pre><code> tabemp = (DataTable)Session["tabempsession"];
  
          if (tabemp.Rows.Count == 1)
          {
  
              if (Convert.ToString(tabemp.Rows[0].ItemArray.GetValue(0)) == "")
              {
                  tabemp.Rows.Clear();
              }
          }
          DataRow drow = tabemp.NewRow();
  
          //create new veriable of(textbox,dropdownlist etc) in ItemTemplate in grid view
  
          TextBox txtFName1 = (TextBox)mygridview.FooterRow.FindControl("txtFName1");         
          TextBox txtLName1 = (TextBox)mygridview.FooterRow.FindControl("txtLName1");
          DropDownList ddlRelation = (DropDownList)mygridview.FooterRow.FindControl("ddlRelation");
          TextBox txtDOB = (TextBox)mygridview.FooterRow.FindControl("txtDOB");
  
          //insert values into rows in tabemp table
          drow[0] = txtFName1.Text;
  
          drow[1] = txtLName1.Text;
          drow[2] = ddlRelation.SelectedItem.Text;
          drow[3] = txtDOB.Text;
  
          tabemp.Rows.Add(drow);
          Session["tabempsession"] = tabemp;
          //int f = tabemp.Rows.Count;
          mygridview.DataSource = (DataTable)Session["tabempsession"];
          mygridview.DataBind();
  </code></pre>
  
  <p>But i am not getting textbox values .ie(txtFName1.Text), its getting as null. Please give me suggestion for getting values of all controls inside gridview.
