                        <Columns>
                           <asp:boundfield datafield="QNo" headerText="#"/>
                            <asp:boundfield datafield="question" />
                            <asp:boundfield datafield="risk_rating" HeaderText="Level" ItemStyle-HorizontalAlign="center" Visible="false"/>
                            <asp:TemplateField headertext="Answer">
                                <ItemTemplate>
                                    <asp:RadioButtonList runat="server" id="rb1Answer" RepeatDirection="Horizontal" RepeatLayout="Flow">
                                        <asp:listitem Text="Yes" value="Yes" />
                                        <asp:listitem Text="No" value="No" />
                                        <asp:listitem Text="N/A" value="N/A" />
                                    </asp:RadioButtonList><br />
                                    <asp:textbox id="txtComments" runat="server" textmode="multiline" height="40" width="600" OnKeyPress="max_Length(event, this, 200)" />
                                    <asp:radiobuttonlist id="rblOptions" runat="server" RepeatLayout="Flow" />
                                </ItemTemplate>
                            </asp:TemplateField>
                        </Columns>
                    </asp:GridView>

after answering the questions, the options that i selected along with my comments must be displayed in the grid.

but now the question column only getting filled. But data saved properly and retrieved.

code behind...

string sql = " select b.Descritpion category, id Qid,ROW_NUMBER()        OVER (ORDER BY id) AS  QNo,  A.Question,C.risk_rating,C.answer,C.comment " +                      " from  AppraisalQuestions A inner Join Questioncategory B On A.Question_Number =b.Categorycode and a.Form='AU'and   isActive = 1  and " + category +
                      " left outer join appraisalanswers c     on a.id= c.question_id  and audit_id  = @id    order by id";

          bindGridView(sql, gvName, _params);

protected virtual void bindGridView(string sql, GridView gv, List<SqlParameter> pars = null, String db = "SSS", CommandType type = CommandType.Text)
  {
      if (gv.AllowPaging)
      {
          gv.DataSource = DAL.executeDataTable(sql, pars, type, db);
          gv.DataBind();
      }
      else
      {
          gv.DataSource = type == CommandType.Text ? DAL.executeQuery(sql, pars, db) : DAL.executeStoredProcedureQuery(sql, pars, db);
          gv.DataBind();
      }
  }

please correct me...
