我使用的是asp.net（C＃）网页表单。我有complaints.aspx页面，它从用户那里获取几个输入，然后在点击SAVE按钮时保存它们。它工作得很好，但现在我遇到了一个问题，我想点击保存按钮打印出提交的记录。它应该从本地打印机打印，但我找不到任何解决方案。
.aspx代码：
<%@ Page Title="" Language="C#" MasterPageFile="~/MasterPage.master" AutoEventWireup="true" CodeFile="frmStaffMembers.aspx.cs" Inherits="frmStaffMembers" %>
<asp:Content ID="Content1" ContentPlaceHolderID="head" Runat="Server">
</asp:Content>
<asp:Content ID="Content2" ContentPlaceHolderID="ContentPlaceHolder1" Runat="Server">
<script type="text/javascript">
$(document).ready(function () {
$("#btnUpdate").hide();
$("#btnDelete").hide();
$("#btnCancel").hide();
$("#lblSelectedID-Span").hide();
$("#txtSelectedID-Span").hide();
var showHide = $("#HiddenFieldShowHideButtons").val();
if (showHide == "True") {
$("#btnUpdate").show();
$("#btnDelete").show();
$("#btnCancel").show();
$("#lblSelectedID-Span").show();
$("#txtSelectedID-Span").show();
$("#buttonSearch").hide();
$("#Save-Span").hide();
$("#HiddenFieldShowHideButtons").val("False");
}
$("#btnUpdate").click(function () {
$("#ConfirmMsg").text("Are you sure to update this record?");
$("#Delete-Span").hide();
$("#lblSelectedID-Span").hide();
$("#txtSelectedID-Span").hide();
$("#Save-Span").show();
$("#buttonSearch").show();
$("#Update-Span").show();
$("#btnUpdate").hide();

$("#btnCancel").hide();
$("#ModalConfirmAction").modal({ show: true })
});
$("#btnDelete").click(function () {
$("#ConfirmMsg").text("Are you sure to delete this record?");
$("#Update-Span").hide();
$("#lblSelectedID-Span").hide();
$("#txtSelectedID-Span").hide();
$("#Delete-Span").show();
$("#Save-Span").show();

});
$("#btnCancel").click(function () {

$("#btnDelete").hide();
$("#btnCancel").hide();

ClearTextBoxes();
});
});
function ClearTextBoxes() {
$("input[type=text]").each(function () {
$(this).val("");
});

我假设你保存后会有某种确认页面？
如果在您的保存事件中如此，您可以添加以下代码，这将自动显示确认页面的打印提示。您不能自己打印客户端，因为它是在最终控制的，但您可以显示打印对话框。
将此服务器端代码添加到Save event：
的末尾ClientScript.RegisterStartupScript(this.GetType(), "FormLoading", "window.print();", true);
确保提供的页面具有您需要的打印数据并且格式正确。您也可以自定义css以应用仅打印样式。
