推荐答案

以下代码可以帮助您入门.您可以使用它并进行所需的更改.希望对您有帮助.
在ASPX文件中，将textbox属性设置为AutoPostBack到true.

Following code can help you in starting. You can use it and make the required changes. Hope it helps you.
In the ASPX file, set the textbox property to AutoPostBack to true.

<![CDATA[<%@ Page Title="Home Page" Language="C#" MasterPageFile="~/Site.master" AutoEventWireup="true" 

    CodeBehind="Default.aspx.cs" Inherits="TestingATextBox._Default" Culture="Auto" %>]]> 
 
<asp:content id="HeaderContent" runat="server" contentplaceholderid="HeadContent" xmlns:asp="#unknown"> 
</asp:content> 
<asp:content id="BodyContent" runat="server" contentplaceholderid="MainContent" xmlns:asp="#unknown"> 
    <table> 
        <tr> 
            <td> 
                <asp:textbox runat="server" id="TextBox1" autopostback="true"> 
                </asp:textbox> 
            </td> 
        </tr> 
        <tr> 
            <td> 
                <asp:button runat="server" id="SaveBtn" text="Save" onclick="SaveBtn_Click" /> 
            </td> 
        </tr> 
    </table> 
</asp:content>

在后面的代码中，单击Save按钮，递增该值.

In the codebehind, on Save button click, increment the value.

public partial class _Default : System.Web.UI.Page 
    { 
        static int i = 1; 
        protected void Page_Load(object sender, EventArgs e) 
        { 
            TextBox1.Text = i.ToString(); 
        } 
 
        protected void SaveBtn_Click(object sender, EventArgs e) 
        { 
            i++; 
        } 
    }
