int index = GridView2.SelectedIndex;

System.Data.DataTable dt = new System.Data.DataTable();
dt = (System.Data.DataTable)ViewState["SelectedRecords"];

DataRow dr = dt.Rows[index];

dr["F1"] = DropDownTitle.SelectedValue ;// is the column name in the datatable
dr["F2"] = txtName.Text;
dr["F3"] = txtSurname.Text ;
dr["F4"] = txtCellNum.Text;
dr["F5"] = txtRef.Text;
dr["F6"] = txtDob.Text;

ViewState["SelectedRecords"] = dt;

GridView2.DataSource = dt;
GridView2.DataBind();
