Hi I am trying to create a list of products from database and show it on the webpage. I am trying to show 3 items in every row.

<asp:ListView ID="ListView_Products" runat="server"
                        DataKeyNames="id"
                        GroupItemCount="3">
                        <GroupTemplate>
                            <tr id="itemPlaceholderContainer" runat="server">
                                <td id="itemPlaceholder" runat="server"></td>
                            </tr>
                        </GroupTemplate>
                        <ItemTemplate>                               
                                <div class="col-sm-4">
                                    <div class="card">
                                        <asp:Image ID="Image1" class="card-img img-fluid" runat="server" Height="200" Width="400" ImageUrl='<%#Eval("pic1") %>' />

                                        <div class="card-body">
                                            <a href="#" class="btn btn-primary stretched-link">View/Update</a>
                                        </div>
                                    </div>

                                </div>                                
                        </ItemTemplate>
                        <LayoutTemplate>
                            <table runat="server" class="listview-host">
                                <tr runat="server">
                                    <td runat="server">
                                        <table id="groupPlaceholderContainer" runat="server">
                                            <tr id="groupPlaceholder" runat="server"></tr>
                                        </table>
                                    </td>
                                </tr>
                                <tr runat="server">
                                    <td runat="server"></td>
                                </tr>
                            </table>
                        </LayoutTemplate>
                    </asp:ListView>

I am using bootstrap Card for this, but Items are not aligning horizontally, each item is coming n a new row. And If I put my card under tag then it does not show Responsive behaviour anymore.
