The common approach is using add, edit, and delete command buttons.

If the the page is not posting at all then you might have validation stopping the post.  Please take a moment to debug your code using dev tools to verify what's happening.

  Yes . Why so . When i commented required field validator then it is posting

<div class="form-group">
                            <asp:Label ID="lblCode" runat="server" CssClass="col-sm-4 control-label" Text="Code"></asp:Label>
                            <div class="col-sm-5">
                                <asp:TextBox ID="txtCode" CssClass="form-control" runat="server"></asp:TextBox>
                                <asp:RequiredFieldValidator ID="rfv1" CssClass="text-danger" runat="server" ErrorMessage="This field is Required !" ControlToValidate="txtCode"></asp:RequiredFieldValidator>
                            </div>
                        </div>
                        <div class="form-group">
                            <asp:Label ID="lblDescription" runat="server" CssClass="col-sm-4 control-label" Text="Description"></asp:Label>
                            <div class="col-sm-8">
                                <asp:TextBox ID="txtDescription"  CssClass="form-control" runat="server"></asp:TextBox>
                                <%--<asp:RequiredFieldValidator ID="rfv2" CssClass="text-danger" runat="server" ErrorMessage="This field is Required !" ControlToValidate="txtDescription"></asp:RequiredFieldValidator>--%>

I believe the problem is self explanatory.  txtDescription is required but a value was not entered.

Maybe you need validation groups?
