1.获取控件里面的子控件：((TextBox)this.fvBSWeekReport.FindControl("txtSiteName")).Text;

          <asp:TemplateField ItemStyle-HorizontalAlign="Center" HeaderText="站点工程图纸">

                <HeaderStyle Wrap="False" />

                <ItemStyle Wrap="False" />

                <ItemTemplate>

                    <span style='display: <%# Eval("FilePath").ToString()!=""? "inline" :"none" %>;'>

                    <a href='<%# Eval("FilePath") %>' runat="server" id="AFilePath">下载</a>

                   </span>

                   <span  style='display: <%# Eval("FilePath").ToString()==""? "inline" :"none" %>;'>

                            <label>图纸未上传</label>

                  </span>

                </ItemTemplate>

            </asp:TemplateField>
