需要从ASP传递动态值.NET文本框到报表查看器中

我认为这是基本的，但我是新的报告工具。

我有一个web表单，我有几个输入控件，我需要从数据库获取值，让他们填充到一个报告。我必须能够在Excel或PDF中获得报告，因此，我选择了提供这些功能的报告查看器。请检查我下面的代码，并给我一个代码或想法，如何通过传递输入参数来开发报告，并得到生成的报告。我的ASPX代码是:

<section id="content" class="has-btn-bar-btm-fixed"><!-- content -->
        <form runat="server" class="form-horizontal custom-form row">
          <div class="cost-transfer-block"><!-- cost-transfer-block -->
                <div class="container-fluid">
                    <div class="row">
                        <div class="col-md-8 col-lg-10">
                            <h2>Dump by item</h2>

                                <div class="col-md-6">
                                    <div class="form-group">
                                        <asp:label runat="server" Text="From Site" ID="lblFromSite" class="control-label col-sm-3 col-md-3 col-lg-3" ></asp:label>
                                        <div class="col-sm-9">
                                            <div class="input-group">
                                                <select class="form-control">
                                                   <asp:DropDownList ID="DdlFromsite" runat="server" ></asp:DropDownList>
                                                </select>
                                                <span class="input-group-addon"><a href="javascript:;">&nbsp;</a></span>
                                            </div>
                                        </div>
                                    </div>

                                </div>
                                <div class="col-md-6 cst-brd-left">
                                    <div class="form-group">

                                        <div class="col-sm-9  transferdate">
                                            <div class="input-group  date">
                                                <input type="date" class="form-control" id="" placeholder="Select Date" >
                                                <span class="input-group-addon"><a href="javascript:;"><img src="images/icon-add-on-2-date.png" alt="" /></a></span>
                                            </div>
                                        </div>
                                    </div>
                                    <div class="form-group">

                                                <input type="date" class="form-control" id="" placeholder="Select Date" >
                                                <span class="input-group-addon"><a href="javascript:;"><img src="images/icon-add-on-2-date.png" alt="" /></a></span>
                                            </div>
                                        </div>
                                    </div>
                                </div>

                        </div>
                        <div class="col-md-4 col-lg-2">
                           &nbsp;
                        </div>
                    </div>
                </div>
          </div>
          <!-- /cost-transfer-block -->
          <div class="gray-btn-row clearfix">
                <div class="btns-group">
                    <asp:button runat="server" Text="Enter" ID="btnEnter" class="btn btn-dark-blue"></asp:button>
                </div>
          </div>
        </form>          
    </section>

请给我一个代码或一个想法，使用它我可以通过点击回车键生成一个报告。

Thanks in Advance，
