.ascx 中的linkbutton事件无法响应
我在student.aspx中响应.ascx ，想在student.aspx中响应.ascx 中的（button）lbtnOK_Click事件，可是运行进却没有响应。student.aspx代码如下：
using System;
using System.Data;
using System.Configuration;
using System.Collections;
using System.Web;
using System.Web.Security;
using System.Web.UI;
using System.Web.UI.WebControls;
using System.Web.UI.WebControls.WebParts;
using System.Web.UI.HtmlControls;
using System.Collections.Generic;
public partial class student : System.Web.UI.Page
{
protected void Page_Load(object sender, EventArgs e)
{
PlaceHolder1.Controls.Clear();
PlaceHolder1.Controls.Add(LoadControl("file/" + "student_information" + ".ascx"));
}
protected void LinkButton2_Click(object sender, EventArgs e)
{
PlaceHolder1.Controls.Clear();
PlaceHolder1.Controls.Add(LoadControl("file/" + "stu_repwd" + ".ascx"));
}
protected void LinkButton3_Click(object sender, EventArgs e)
{
PlaceHolder1.Controls.Clear();
PlaceHolder1.Controls.Add(LoadControl("file/" + "stu_course" + ".ascx"));
}
protected void LinkButton4_Click(object sender, EventArgs e)
{
PlaceHolder1.Controls.Clear();
PlaceHolder1.Controls.Add(LoadControl("file/" + "stu_choosecourse" + ".ascx"));
}
protected void LinkButton5_Click(object sender, EventArgs e)
{
}
protected void LinkButton5_Click1(object sender, EventArgs e)
{
PlaceHolder1.Controls.Clear();
PlaceHolder1.Controls.Add(LoadControl("file/" + "stu_grate" + ".ascx"));
}
protected void LinkButton1_Click(object sender, EventArgs e)
{
}
}
.ascx中代码如下：
using System;
using System.Collections;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Web;
using System.Web.Mobile;
using System.Web.SessionState;
using System.Web.UI;
using System.Web.UI.MobileControls;
using System.Web.UI.WebControls;
using System.Web.UI.HtmlControls;
using System.Data.SqlClient;
public partial class file_stu_repwd : System.Web.UI.MobileControls.MobileUserControl
{
datams dm = new datams();
protected void Page_Load(object sender, EventArgs e)
{
}
protected void lbtnOK_Click(object sender, EventArgs e)
{
if (txtOldpwd.Text == "" || txtNewpwd.Text == "" || txtRepwd.Text == "")
{
lblMsg.Text = "<b>数据输入不完整，请重新输入！</b>";
return;
}
if (txtNewpwd.Text != txtRepwd.Text)
{
lblMsg.Text = "<b>两次输入的密码不相同！</b>";
return;
}
SqlConnection con = dm.getconn();
con.Open();
string sqlstr = "update users set User_password='" + txtNewpwd.Text + "' where User_id=@id";
SqlCommand com = dm.getcom(sqlstr);
com.Parameters.Add(new SqlParameter("@id", SqlDbType.VarChar, 50));
com.Parameters["@id"].Value = Session["user_id"].ToString();
try
{
com.ExecuteNonQuery();
lblMsg.Text = "<b>修改成功！</b>";
}
catch (SqlException)
{
lblMsg.Text = "<b>修改失败！</b>";
}
con.Close();
}
protected void lbtnBack_Click(object sender, EventArgs e)
{
Response.Redirect("default.aspx");
}
}
--------------------编程问答-------------------- 委托实现
用户控件中定义
public event EventHandler BtnEvent;
private void Btn_Click(object sender, System.EventArgs e)
{
if (BtnEvent != null)
{
BtnEvent(sender,e);
}
}
override protected void OnInit(EventArgs e)
｛
btn.BtnEvent += new EventHander(this.test);
｝
private void A(object sender ,System.EventArgs e)
{
}
补充：.NET技术 , ASP.NET
