  1.   

     <br />
      <asp:LinkButton ID="LinkButton1" runat="server" onClick="LinkButton1_Click">LinkButton</asp:LinkButton>
      <br />
      <asp:ImageButton ID="ImageButton1" runat="server" Height="26px" Width="27px" onClick="ImageButton1_Click">/>
      

  2.   

    <asp:LinkButton ID="LinkButton1" runat="server" onClick=“LinkButton1_Click”>LinkButton</asp:LinkButton>
      

  3.   


    <asp:Button ID="Button1" runat="server" Text="click me" OnClick="Button1_Click" />
    <br />
    <asp:LinkButton ID="LinkButton1" runat="server" OnClick="LinkButton1_Click" >LinkButton</asp:LinkButton>
    <br />
    <asp:ImageButton ID="ImageButton1" runat="server" OnClick="ImageButton1_Click" Height="26px" Width="27px" />
      

  4.   

    上面都说得比较清楚了你就是在aspx页面,每个控件后上了OnClick,点击事件没有关联起来
      

  5.   

    在双击前台页面的按钮的时候会跑出来一个事件的在后台代码那的，特意写了个例子给你了，给点分*.*  想发帖都没份了<%@ Page Language="C#" AutoEventWireup="true" CodeFile="Default2.aspx.cs" Inherits="web_Default2" %><!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"><html xmlns="http://www.w3.org/1999/xhtml">

    </head>
    <body>
        <form id="form1" runat="server">
        <div>
        
            <asp:Label ID="Label1" runat="server"></asp:Label>
            <asp:Button ID="Button1" runat="server" onclick="Button1_Click" Text="Button" />
            <asp:LinkButton ID="LinkButton1" runat="server" onclick="LinkButton1_Click">LinkButton</asp:LinkButton>
            <asp:ImageButton ID="ImageButton1" runat="server" Height="16px" onclick="ImageButton1_Click" Width="67px" />
        
        </div>
        </form>
    </body>
    </html>这是后台using System.Web;
    using System.Web.Security;
    using System.Web.UI;
    using System.Web.UI.HtmlControls;
    using System.Web.UI.WebControls;
    using System.Web.UI.WebControls.WebParts;
    using System.Xml.Linq;public partial class web_Default2 : System.Web.UI.Page
    {
        protected void Page_Load(object sender, EventArgs e)
        {
               }
        protected void Button1_Click(object sender, EventArgs e)
        {
            Label1.Text = "button";    }
        protected void LinkButton1_Click(object sender, EventArgs e)
        {
            Label1.Text = "链接按钮被触发";    }
        protected void ImageButton1_Click(object sender, ImageClickEventArgs e)
        {
            Label1.Text = "图片按钮被触发";    }
    }
