后端WebUserControl1.ascx代码
/// <summary>/// Author: Fly/// Date: 2022-03-03/// Dsc: 用户控件/// </summary>public partial class WebUserControl1 : System.Web.UI.UserControl{protected void Page_Load(object sender, EventArgs e){//labYear.Text = DateTime.Now.ToString("yyyy"); }public void SetVul(string str){labYear.Text = str;}}
- 新建WebForm1.aspx调用用户控件
<%@ Page Language="C#" AutoEventWireup="true" CodeBehind="WebForm1.aspx.cs" Inherits="Web.Control.Demo.WebForm1" %><%@ Register Src="~/WebUserControl1.ascx" TagPrefix="uc1" TagName="WebUserControl1" %><!DOCTYPE html><html xmlns="http://www.w3.org/1999/xhtml">
<head runat="server">
<meta http-equiv="Content-Type" content="text/html; charset=utf-8"/><title></title>
</head>
<body><form id="form1" runat="server"><div><uc1:WebUserControl1 runat="server" id="WebUserControl1" /><br /> <asp:Button ID="Button1" runat="server" Text="获取用户控件数据" OnClick="Button1_Click" /></div></form>
</body>
</html>- 在WebForm1.aspx页面后端获取用户控件的ID并赋值和读取控件信息
public partial class WebForm1 : System.Web.UI.Page{protected void Page_Load(object sender, EventArgs e){//WebUserControl1.SetVul("Hello World");//获取用户控件中的服务器控件ID，并赋值Label label = WebUserControl1.FindControl("labYear") as Label;label.Text = "Fly";}protected void Button1_Click(object sender, EventArgs e){//获取用户控件中的服务器控件ID，并读取控件信息Label label = WebUserControl1.FindControl("labYear") as Label;Response.Write(label.Text);}}
