ASPX页面中的“打印”按钮

Question

I have quick question. I have a table in ASPX page and I am trying to make my Print functionality work. I would like to Print particular row when a row is selected and print whole table when now row is selected. i am able to make selected row work. but i am not able print whole table when no row is selected. Is it okay to have same print button to do both functionalities or do i need to use different button. thank you

 function PrintPage() { //var printContent = document.getElementById('<= SessionNotes.ClientID %>'); var printContent = document.getElementById('printsessionNote'); var printWindow = window.open("Selected Row", "Print Panel", 'left=50000,top=50000,width=0,height=0'); printWindow.document.write(printContent.innerHTML); printWindow.document.close(); printWindow.focus(); printWindow.print(); return false; } function Divprint(category,date,starttime,endtime,totaltime,staff,note) { $('#lblDateval').html(date); $('#lblCategoryval').html(category); $('#lblstarttimeal').html(starttime); $('#lblEndtimeal').html(endtime); $('#lblTotaltimeal').html(totaltime); $('#lblstaffphysicianal').html(staff); $('#lblnote').html(note); return false; } 

  <asp:HiddenField ID="hdn_FromID" runat="server" Value="" /> <asp:HiddenField ID="hdn_ToId" runat="server" Value="" /> <div id="printsessionNote" runat="server"> <table style="width:100%"> <tr> <td>Date</td> <td>Category</td> <td>Start Time</td> <td>End Time</td> <td>Total Time</td> <td>Staf/Physician</td> </tr> <tr> <td><label id="lblDateval"></label></td> <td><label id="lblCategoryval"></label></td> <td><label id="lblstarttimeal"></label></td> <td><label id="lblEndtimeal"></label></td> <td><label id="lblTotaltimeal"></label></td> <td><label id="lblstaffphysicianal"></label></td> </tr> <tr> <td colspan="6"> Note : <label id="lblnote"></label> </td> </tr> </table> </div> <div> <asp:Button ID="btnprintpatientlist" runat="server" Text="Print" OnClientClick=" javascript:return PrintPage();" BackColor="#FFCB05" Width="100px" Height="30" BorderWidth="0" /> <asp:Button ID="btndownloadpdf" runat="server" Text="Download" BackColor="#FFCB05" Width="100px" Height="30" BorderWidth="0" OnClick="btnExport_Click"/> </div> <p hidden="hidden" class="ses-pls">Please Select the session note(s) to print or select 'Print' to 'Print all'</p> </div> 

Answer 1

Just use a flag to to judge if a row is selected.When a row is selected,print the row's outerHTML.If not,print the table's outerHTML. If you want to do both,remove the first method's 'return false'.
