登录控件需点击2次才能登录，如何解决？
asp.net中将登录控件放进母版页，可是在test页面中登录要点击两次登录才能够起到登录功能，请问该怎么修改？？
登录控件代码如下：
protected void Page_Load(object sender, EventArgs e)
{
if (Session["user"] != null)
{
TB_BBSUSERS user = (TB_BBSUSERS)Session["user"];
Label1.Text = "欢迎 " + Session["username"] + " 进入!";
MultiView1.ActiveViewIndex = 1;//用MultiView控件，里面放置2个View
}
else
{
MultiView1.ActiveViewIndex = 0;
}
}
protected void LinkButton2_Click(object sender, EventArgs e)
{
string strCheck = TextBox1.Text.ToString();
if (Regex.IsMatch(strCheck, "^[0-9]+$") == true)//判断账号是否为数字账号，必须的！
{
string id = TextBox1.Text;
string pwd = TextBox2.Text;
TB_BBSUSERS user = new TB_BBSUSERS();//三层结构代码
BBSUSERSDAL bbsdal = new BBSUSERSDAL();//三层结构代码
DataTable dt = new DataTable();
dt=bbsdal.FindTeDingUsers(id);//三层结构代码
if (dt.Rows.Count != 0)
{
user.u_userPsw = dt.Rows[0]["u_userPsw"].ToString();
user.u_userName = dt.Rows[0]["u_userName"].ToString();
user.u_roleId = Convert.ToInt32(dt.Rows[0]["u_roleId"]);
Session["roleid"] = user.u_roleId;//将用户资料放入Session中以便判断
if (user.u_userPsw==pwd)
{
Session["user"] = user;
Session["username"] = user.u_userName;
}
else
{
this.Page.ClientScript.RegisterClientScriptBlock(this.GetType(), "", "alert('账号或者密码错误！请重新登录！');", true);
}
}
else
{
this.Page.ClientScript.RegisterClientScriptBlock(this.GetType(), "", "alert('账号或者密码错误！请重新登录！');", true);
}
}
else
{
this.Page.ClientScript.RegisterClientScriptBlock(this.GetType(), "", "alert('必须输入数字账号！请重新登录！');", true);
}
}
protected void LinkButton1_Click(object sender, EventArgs e)
{
Session.Abandon();
this.Page.ClientScript.RegisterClientScriptBlock(this.GetType(), "", "alert('注销成功！即将返回主页面！');", true);
//Response.Redirect("~/Default.aspx");//注销链接到首页
}
protected void LinkButton3_Click(object sender, EventArgs e)
{
Response.Redirect("~/Perpon.aspx?id={0}");//链接到个人中心
}
[解决办法]
设置断点，单步跟踪
是否页面初始多次
